D)none of the In nutrition, diet is the sum of food consumed by a person or other organism.[1] Dietary habits are the habitual decisions an individual or culture makes when choosing what foods to eat. Each culture and each person holds some food preferences or some food taboos. This may be due to personal tastes or ethical reasons. Individual dietary choices may be more or less healthy. Proper nutrition requires ingestion and absorption of vitamins, minerals, and food energy in the form of carbohydrates, proteins, and fats. Dietary habits and choices play a significant role in the quality of life, health and longevity. It can define cultures and play a role in religion. ALTERNATE EATING PRACTICE Ovo vegetarianism Possible missing/low nutrition components Calcium, vitamin D, essential amino acids, omega-3 fatty acids and vitamin B12 Provides sufficient nutrition to support healthy functioning?? -may require tuning or supplementation such as vitamins to meet ordinary nutritional needs. - by eating a variety of complementary plant sources that, in combination, provide all eight essential amino acids ALTERNATE EATING PRACTICES HS20-NM2 OUTCOME Vegetarianism is the practice of abstaining from the consumption of meat – red meat, poultry, seafood and the flesh of any other animal; it may also include abstention from by-products of animal slaughter. There are a number of vegetarian diets, which exclude or include various foods. Ovo vegetarianism includes eggs but not dairy products. Lacto vegetarianism includes dairy products but not eggs. Ovo-lacto vegetarianism (or lacto-ovo vegetarianism) includes animal/dairy products such as eggs, milk, and honey. Veganism excludes all animal flesh and products, such as milk, honey, and eggs, as well as items refined or manufactured through any such product, such as bone-char refined white sugar or animal-tested baking soda. Raw veganism includes only fresh and uncooked fruit, nuts, seeds, and vegetables. Vegetables can only be cooked up to a certain temperature.[23] Fruitarianism permits only fruit, nuts, seeds, and other plant matter that can be gathered without harming the plant.[24] Sattvic diet (also known as yogic diet), a plant based diet which may also include dairy (not eggs) and honey, but excludes anything from the onion or leek family, red lentils, durian fruit, mushrooms, blue cheeses, fermented foods or sauces, alcoholic drinks and often also excludes coffee, black or green tea, chocolate, nutmeg or any other type of stimulant such as excess sharp spices. Buddhist vegetarianism. Different Buddhist traditions have differing teachings on diet, which may also vary for ordained monks and nuns compared to others. Many interpret the precept 'not to kill' to require abstinence from meat, but not all. In Taiwan, su vegetarianism excludes not only all animal products but also vegetables in the allium family (which have the characteristic aroma of onion and garlic): onion, garlic, scallions, leeks, chives, or shallots. Jain vegetarianism includes dairy but excludes eggs and honey, as well as root vegetables. Macrobiotic diets consist mostly of whole grains and beans. Western vegetarian diets are typically high in carotenoids, but relatively low in omega-3 fatty acids and vitamin B12. Vegans can have particularly low intake of vitamin B and calcium if they do not eat enough items such as collard greens, leafy greens, tempeh and tofu (soy).[citation needed] High levels of dietary fiber, folic acid, vitamins C and E, and magnesium, and low consumption of saturated fat are all considered to be beneficial aspects of a vegetarian diet. Protein intake in vegetarian diets is only slightly lower than in meat diets and can meet daily requirements for any person, including athletes and bodybuilders.[49] Studies at Harvard University as well as other studies conducted in the United States, United Kingdom, Canada, Australia, New Zealand and various European countries, confirmed vegetarian diets provide sufficient protein intake as long as a variety of plant sources are available and consumed.[50] Proteins are composed of amino acids, and a common concern with protein acquired from vegetable sources is an adequate intake of the essential amino acids, which cannot be synthesised by the human body. While dairy and egg products provide complete sources for ovo-lacto vegetarian, several vegetable sources have significant amounts of all eight types of essential amino acids, including lupin beans, soy,[51] hempseed, chia seed,[52] amaranth,[53] buckwheat,[54] pumpkin seeds[55] spirulina,[56] pistachios,[57] and quinoa.[58] However, the essential amino acids can also be obtained by eating a variety of complementary plant sources that, in combination, provide all eight essential amino acids (e.g. brown rice and beans, or hummus and whole wheat pita, though protein combining in the same meal is not necessary[citation needed]). A 1994 study found a varied intake of such sources can be adequate. These diets may require tuning or supplementation such as vitamins to meet ordinary nutritional needs. Scientific endeavors in the area of vegetarianism have shifted from concerns about nutritional adequacy to investigating health benefits and disease prevention.[30] The Academy of Nutrition and Dietetics and Dietitians of Canada have stated that at all stages of life, a properly planned vegetarian diet is "healthful, nutritionally adequate, and provides health benefits in the prevention and treatment of certain diseases".[31] Large-scale studies have shown that mortality from ischaemic heart disease was 30% lower among vegetarian men and 20% lower among vegetarian women than in non-vegetarians.[32][33] Vegetarian diets offer lower levels of saturated fat, cholesterol and animal protein, and higher levels of carbohydrates, fibre, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals.[34][35] Vegetarians tend to have lower body mass index,[36] lower levels of cholesterol, lower blood pressure, and less incidence of heart disease, hypertension, type 2 diabetes, renal disease, metabolic syndrome,[37] dementias such as Alzheimer's disease and other disorders Carbohydrate Loading, commonly referred to as carb-loading or carbo-loading, is a strategy used by endurance athletes, such as marathon runners, to maximize the storage of glycogen (or energy) in the muscles. Carbohydrate loading is also used in healthcare to optimise the condition of patients prior to colorectal surgery.[1] Carbohydrate loading is generally recommended for endurance events lasting longer than 90 minutes.[2] Many endurance athletes prefer foods with low glycemic indices for carbo-loading due to their minimal effect on serum glucose levels. Low glycemic foods commonly include fruits, vegetables, whole wheat pasta, and grains. Many marathoners and triathlon participants have large pasta dinners the night before the race. Since muscles also use amino acids extensively when functioning within aerobic limits, meals should also include adequate protein.[3] Large portions before a race can, however, decrease race-day performance if the digestive system has not had the time to process the food regimen. Most dietary carbohydrates consist of varying proportions of two simple sugars, glucose and fructose. Fructose may be metabolized into liver glycogen, but it is ineffective at raising muscle glycogen levels (which is the objective of carbohydrate loading).[6] Consequently, sources of high-fructose carbohydrates, such as fruit and sweets, are less than optimal for the task. The classic carb-loading meal is pasta, whose caloric content is primarily due to starch, a glucose polymer. High-glucose meals which include bread, rice, and potatoes are all part of the correct regimen. The biggest downside to carbohydrate loading is that Glycogen is stored with additional water. Generally, 2-5 grams of water are stored with each gram of Glycogen, so carbohydrate loading adds extra weight. If the race does not require the extra Glycogen supplies, then the extra weight will degrade performance. Maintaining this calorie intake for a day should not cause a significant gain in body fat, but longer periods may be problematic. Detox diets involve either not consuming or attempting to flush out substances that are considered unhelpful or harmful. Examples include restricting food consumption to foods without colourings or preservatives, taking supplements, or drinking large amounts of water. The latter practise in particular has drawn criticism, as drinking significantly more water than recommended levels can cause hyponatremia(water poisoning) Juice fasting: A form of detox diet, in which nutrition is obtained solely from fruit and vegetable juices. The health implications of such diets are disputed. Low Carb diet: diet based on limiting carbohydrate consumption combined with low fat protein to maintain muscle. Some clinicians[25] regard restricting a diet from all carbohydrates as unhealthy and dangerous, as it results in ketosis. However, it is not necessary to completely eliminate all carbohydrates from the diet in order to achieve a state of ketosis. Other clinicians regard ketosis as a safe biochemical process that occurs during the fat-burning state. Type 1 diabetics and long-term type II diabetics, are liable to enter an unsafe level of ketosis, causing an eventual comatose state that requires emergency medical treatment. Low Glycemic-Index diet: is one that selects foods on the basis of minimal alteration of circulating glucose levels. Glycemic index (GI) and glycemic load (GL) are measures of the effect on blood glucose level after a food containing carbohydrates is consumed. Glucose is one of the body's main sources of energy; it is the fuel used by the brain, muscles, and other organs. Glucose is set at 100, and all foods are indexed against that number. Low GI foods affect blood glucose and insulin levels less and have a slower rate of digestion and absorption. Switching from a high glycemic index diet to a low glycemic index diet is considered to be relatively easy. Switching from white bread and pastas to whole grain, from breakfast cereals to oats, bran or barley, adding more fruits and vegetables when cooking, and reducing potato consumption can all aid in lowering glycemic index. A diet based on foods with low glycemic response has been associated with diabetes management, improved blood lipids (cholesterol), and reduced risk of heart disease. [2][unreliable source?]. Not only will foods with a low glycemic index take longer to digest (therefore prolonging satiety) they will also maintain blood glucose levels at a relatively constant state. Foods with a high glycemic index not only digest quickly, but they also can cause extreme fluctuations in blood glucose. There are some specific factors to consider in foods that can indicate their glycemic index. Low glycemic foods contain fat, protein, fiber, whole grains, raw starches, legumes, vegetables, fruits and dairy products. High glycemic foods contain refined grains, refined sugars, and increased amylopectin/amylose ratio. There are other factors that contribute to a food's glycemic index, such as plant variety, ripeness, food processing, cooking method, and the other foods served with it. Low-calorie diets: the key to reaching and maintaining the desired weight is understanding and carefully monitoring calories consumed and used. Gluten-free diet: A diet which avoids the protein gluten, which is found in barley, rye and wheat. It is a medical treatment for coeliac disease and gluten sensitivity.[ Ketogenic diet: A high-fat, low-carb diet, in which dietary and body fat is converted into energy. Used as a medical treatment for refractory epilepsy.[43] Fasting: Fasting is primarily an act of willing abstinence or reduction from certain or all food, drink, or both, for a period of time. During the overnight fast the body naturally switches into ketosis, and will switch back to glycolysis after a carbohydrate-rich meal. Longer-term ketosis may result from fasting or staying on a low-carbohydrate low-GI diet. Extended fasting has been recommended as therapy for various conditions by health professionals of many cultures, throughout history, from ancient to modern. Fasting is also a part of many religious observances like the Bahá'í Faith. Liquid diet: A diet in which only liquids are consumed. May be administered by clinicians for medical reasons, such as after a gastric bypass[44] or to prevent death through starvation from a hunger strike. Junk food diet: A diet largely made up of food considered to be unhealthy, such as high-fat or processed foods. fast foods are commonly high in fat content, and studies have found associations between fast food intake and increased body mass index (BMI) and weight gain.[2] In particular many fast foods are high in saturated fats which are widely held to be a risk factor in heart disease. Kosher diet: Food permissible under Kashrut, the set of Jewish dietary laws, is said to be Kosher. Some foods and food combinations are non-Kosher, and failure to prepare food in accordance with Kashrut can make otherwise permissible foods non-Kosher Crash diet and fad diet are general terms. They describe diet plans which involve making extreme, rapid changes to food consumption, but are also used as disparaging terms for common eating habits which are considered unhealthy. Both types of diet are often considered to pose health risks. Cabbage soup diet: A low-calorie diet based on heavy consumption of cabbage soup. Considered a fad diet.[24] large Grapefruit diet: A fad diet, intended to facilitate weight loss, in which grapefruit is consumed in quantities at meal times.[25] An eating disorder is a mental disorder that interferes with normal food consumption. It is defined by abnormal eating habits that may involve either insufficient or excessive diet. Anorexia nervosa (AN), characterized by lack of maintenance of a healthy body weight, an obsessive fear of gaining weight or refusal to do so, and an unrealistic perception, or non- recognition of the seriousness, of current low body weight. Anorexia can cause menstruation to stop, and often leads to bone loss, loss of skin integrity, etc. It greatly stresses the heart, increasing the risk of heart attacks and related heart problems. The risk of death is greatly increased in individuals with this disease.[25] The most underlining factor researchers are starting to take notice of is that it may not just be a vanity, social, or media issue, but it could also be related to biological and or genetic components.[26] Bulimia nervosa (BN), characterized by recurrent binge eating followed by compensatory behaviors such as purging (self-induced vomiting, excessive use of laxatives/diuretics, or excessive exercise). Fasting and overexercising may also be used as a method of purging following a binge. Binge eating disorder (BED), characterized by binge eating at least 2-3 times a week Energy Drinks: the general population of healthy adults is not at risk for potential adverse effects from caffeine if they limit their consumption to 400 mg per day. As is the case with other caffeinated beverages, Red Bull drinkers may experience adverse effects as a result of overuse. Moderate caffeine intake (less than 400 mg per day) does not adversely affect cardiovascular health. Combining considerable amounts of caffeine and alcohol may cause negative side effects. When caffeine and alcohol are combined, the consumer does not necessarily feel the effects of the alcohol as the caffeine keeps them awake.[1] This often causes the consumer to drink more than they normally would because of the delayed "drunk" feeling, as caffeine can mask some of the sensory cues individuals might normally rely on to determine their level of intoxication.[2] The Food and Drug Administration (FDA) has looked at peer-reviewed studies and has come to the conclusion that risky behaviors which could lead to life-threatening situations are directly correlated with the consumption of caffeinated alcoholic beverages. In Canada, regulations restrict the manufacture and sale of caffeinated alcoholic drinks unless the caffeine comes from natural sources such as guarana; manufactured caffeine cannot be directly poured into an alcoholic beverage The 100-Mile Diet or locavores(Local Eating movements): Canadians that restricting the diet to include only foods grown within 100 miles of their residence. Finding little in grocery stores, they relied on farmers' markets and visits to local farms. Staples in their diet included fish, beef,chicken, root vegetable, berries,beans,greens, and corn. They lacked cooking oils, rice, and sugar. Honey replaced sugar.

Disease The term disease broadly refers to any condition that impairs normal function, and is therefore associated with dysfunction of normal homeostasis.[5] Commonly, the term disease is used to refer specifically to infectious diseases, which are clinically evident diseases that result from the presence of pathogenic microbial agents, including viruses, bacteria, fungi, protozoa, multicellular organisms such as parasitic worms, and aberrant proteins known as prions. Illness Illness and sickness are generally used as synonyms for disease.[6] However, this term is occasionally used to refer specifically to the patient's personal experience of his or her disease.[7][8] In this model, it is possible for a person to have a disease without being ill (to have an objectively definable, but asymptomatic, medical condition), and to be ill without being diseased (such as when a person perceives a normal experience as a medical condition, or medicalizes a non-disease situation in his or her life) Disorder In medicine, a disorder is a functional abnormality or disturbance. The term disorder is often considered more value-neutral and less stigmatizing than the terms disease or illness, and therefore is a preferred terminology in some circumstances. Medical condition A medical condition is a broad term that includes all diseases, any illness, injury, and disorders. Syndrome A syndrome is the association of several medical signs, symptoms, and or other characteristics that often occur together. Some syndromes, such as Down syndrome, have only one cause; others, such as Parkinsonian syndrome, have multiple possible causes. In other cases, the cause of the syndrome is unknown. Non-communicable diseases is a medical condition or disease which by definition is non-infectious and nontransmissible among people. NCDs may be chronic diseases of long duration and slow progression, or they may result in more rapid death such as some types of sudden stroke. They include autoimmune diseases, heart disease, stroke, many cancers, asthma, diabetes, chronic kidney disease, osteoporosis, Alzheimer's disease, cataracts, and more. Lifestyle diseases A lifestyle disease is any disease that appears to increase in frequency as countries become more industrialized and people live longer, especially if the risk factors include behavioral choices like a sedentary lifestyle or a diet high in unhealthful foods such as refined carbohydrates, trans fats, or alcoholic beverages. Acute disease An acute disease is a short-lived disease, like the common cold. Chronic disease A chronic disease is one that lasts for a long time, usually at least six months. During that time, it may be constantly present, or it may go into remission and periodically relapse. Progressive disease Progressive disease is a disease whose typical natural course is the worsening of the disease until death, serious debility, or organ failure occurs. Slowly progressive diseases are also chronic diseases; many are also degenerative diseases. The opposite of progressive disease is stable disease or static disease: a medical condition that exists, but does not get better or worse Degenerative disease is a disease in which the function or structure of the affected tissues or organs will increasingly deteriorate over time, whether due to normal bodily wear or lifestyle choices such as exercise or eating habits.[1] Degenerative diseases are often contrasted with infectious diseases.They include diseases of the heart, joints and nervous system. Genetic disorder is an illness caused by one or more abnormalities in the genome, especially a condition that is present from birth (congenital). Most genetic disorders are quite rare and affect one person in every several thousands or millions. Genetic disorders may or may not be heritable, i.e., passed down from the parents' genes. In non-heritable genetic disorders, defects may be caused by new mutations or changes to the DNA. In such cases, the defect will only be heritable if it occurs in the sperm or egg or the cells that give rise to them. Congenital disorder, or congenital disease, is a condition existing at birth and often before birth, or that develops during the first month of life (neonatal disease), regardless of causation. Of these diseases, those characterized by structural deformities are termed "congenital anomalies" and involve defects in or damage to a developing fetus. Metabolic disorders problems arise due to accumulation of substances which are toxic or interfere with normal function, or to the effects of reduced ability to synthesize essential compounds. Infectious diseases is a sickness that happens when an organism (a living thing such as a plant or animal) is attacked by a pathogen. Pathogens (such as bacteria, viruses, and other germs) are too small to see. Some infectious diseases are contagious, which means that the sick plant, animal, or person can get other things sick. The pathogen can get from one organism to another through air, food, water, blood, or physical touch. Contagious diseases is a subset category of infectious diseases (or communicable diseases), which are easily transmitted by physical contact (hence the name-origin) with the person suffering the disease, or by their secretions or objects touched by them.[1] The non-contagious category of infectious/communicable diseases usually require a special mode of transmission between hosts. These include need for intermediate vector species (mosquito that cause malaria) or transfer of bodily fluid (such as transfusions, needle-sharing or sexual contact). The boundary between contagious and non-contagious infectious diseases is not perfectly drawn, as illustrated classically by tuberculosis, which is clearly transmissible from person to person, but was not classically considered a contagious disease. In the present day, most sexually transmitted diseases are considered contagious, but only some of them are subject to medical isolation Communicable diseasesillnesses caused by microorganisms and transmitted from an infected person or animal to another person or animal. Airborne diseases is any disease that is caused by pathogens and transmitted through the air. The relevant pathogens may be viruses, bacteria, or fungi, and they may be spread through coughing, sneezing, raising of dust, spraying of liquids, or similar activities likely to generate aerosol particles or droplets. Strictly speaking airborne diseases do not include conditions caused simply by air pollution such as dusts and poisons, though their study and prevention may be related. Food borne illness Food borne illness or food poisoning is any illness resulting from the consumption of food contaminated with pathogenic bacteria, toxins, viruses, prions or parasites. Vector-borne disease In epidemiology, a vector is any agent (person, animal or microorganism) that carries and transmits an infectious pathogen into another living organism. There is often a reservoir species important in epidemiology. Natural reservoir or nidus (the latter from the Latin word for "nest") refers to the long-term host of the pathogen of an infectious disease.[1] It is often the case that hosts do not get the disease carried by the pathogen or it is carried as a subclinical infection and so asymptomatic and nonlethal. Once discovered, natural reservoirs elucidate the complete life cycle of infectious diseases, providing effective prevention and control. eg. Deer mice are the natural reservoir for hantaviruses. They do NOT get the hemorrhagic fevers but can trasmit them to humans.

The story begins with the Health Products and Food Branch (HPFB), which has a little known advisory committee known as the ACNF - Advisory Committee for Nutritional Food. And their mission is to promote the most nutritional diet in the interest of the public good. After a period of study and deliberations, they came up with Recommended Daily Amounts of each type of food to include at least 3 servings of meat per day, preferably Big Macs, Whoppers and Chicken Dinners. They've called this optimal diet FAD which stands for Federally Approved Diet. They have published their FAD diet and other recommendations in a special government report. Before long, your state legislators took note of this official government report and acting in what they felt was the public's best interest, they passed a law which made the FAD diet mandatory. And, just to make sure that all citizens follow this government approved diet, the law mandates that neither you nor your children can attend school (including college) unless you eat the government's FAD diet. So, one day during a class discussion on nutrition your daughter or granddaughter happens to mention that she and her family are.....VEGETARIANS. Well, within a few days her parents receive a very threatening letter from school officials which makes it clear that the little girl will be expelled from school unless her parents start feeding her the FAD diet. School officials also make it clear that if her parents are particularly stubborn in refusing to comply with the government-mandated FAD diet, that Child Protective Services will be called and they will likely take the little girl away from her parents based on "NUTRITIONAL NEGLECT" of a child. Well, being vegetarians, a very bright and independent thinking group of people, the parents said "Hey, wait a minute.... this is Canada, not communist China. Government has no right to tell me what I put into my body or into my child's body." And these inquisitive vegetarians began asking some questions that made school and government officials very very uncomfortable. They asked "Who are the members of this government advisory committee on nutritional foods that have advocated that my child eat Big Macs, Whoppers and Chicken Dinners? And, will you show us the scientific data which supports their conclusions?" "If this is all being done for the public good, then the public should have the right to know who is making these decisions that affect everyone and what does the process entail?" Well, the government bureaucrats did not like this line of questioning one bit. Because, what the vegetarians found out was that the ACNF, the advisory committee on nutritional foods, was composed of representatives from..... McDonalds, Burger King and Kentucky Fried Chicken. And, despite their request to see the actual scientific data that was used to develop this government-mandated FAD diet, the government refused to give this information to the vegetarians because members of the committee said that the data contained proprietary, trade secrets that were protected by patent and could, therefore, not be divulged to the public. It thus became clear to the vegetarians that there was something very rotten about the government's compulsory FAD diet. Can you imagine what this mandatory FAD diet would do for the sales of McDonalds, Burger King and Kentucky Fried Chicken? A government mandate which would require people to eat this FAD diet would constitute a guaranteed market, a veritable goldmine for the purveyors of red and white meat. Now having told that little story, I want to emphasize to you that the story is pure fiction Health Problems(in order of study in HS 20) A disease is a particular abnormal, pathological condition that affects part or all of an organism. It is often construed as amedical condition associated with specific symptoms andsigns.[1] It may be caused by factors originally from an external source, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases. In humans, "disease" is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories 1. Non-transmissable diseases are all other diseases, including most forms of cancer, heart disease, degenerative diseases (Diseases of the heart, joints and nervous system), genetic disorders, autoimmune diseases , injuries, disabilities, endocrine/metabolic disorders, allergies , or high blood pressure. eg. DIABETES(don't forget recombinant DNA to get bacteria to make human insulin!!!) syndromes (eg. SAVANT SYNDROME AND AQUIRED SS) Virulence (the tendency of a pathogen to cause damage to a host's fitness) and 2.Pathogens(usually a microorganism - not viruses and prions that cause kuru and CJD = Creutzfeldt–Jakob disease) = BACTERIAL and food borne illness (Typhoid Mary story of person who prepares food for large groups of people refrigeration, preservation, cooking, sanitary habits), VIRAL including chronic carrier state may occur in the following: Hantavirus Infection Hepatitis A B and C +Smallpox, ANTIBIOTICS SUPERBUGS PARASITIC, FUNGAL, PRION MYTHBUSTERS OUTBREAKS/EPIDEMICS/PANDEMICS *****http://healthmap.org/en/ to follow global/local outbreaks!!!!! [Transmissible diseases: Transmission of pathogens occurs through many different routes, including airborne, droplet dispersal of a sneeze/cough/talking/breathing, vector borne, Zoonoses (=transmissible between man and one or more other species) with an animal reservoir(that does not die of the disease!!!!), water or food borne(Some diseases are caused by drinking water that is contaminated by human or animal feces, which may contain disease-causing microbes. Clean water, hygiene and good sewerage systems prevent the spread of water-borne diseases such as typhoid and cholera.), direct or indirect contact with infected people, on surfaces or materials, through contact with objects contaminated with infected body fluids like contaminated syringes and needles , sexual contact, through blood to blood, through breast milk or other body fluids, or ingesting prions, and through the fecal-oral route. ] also infectious diseases Contagious diseases Communicable diseases: Zoonotic or vector-borne Infectious Diseases (VIDEOS) (A vector‐borne disease is one in which the pathogenic microorganism is transmitted from an infected individual to another individual by an arthropod or other agent like a syringe, sometimes with other animals serving as intermediary hosts. Zoonotic means that these viruses naturally reside in an animal reservoir carrier host or arthropod vector that does not die of the disease. They are totally dependent on their hosts for replication and overall survival. Smallpox and poliomyelitis virus have no animal reservoir. The lack of a non-human reservoir makes these viruses good candidates for eradication efforts. For the most part, rodents and arthropods are the main reservoirs for viruses . The multimammate rat, cotton rat, deer mouse, house mouse, and other field rodents are examples of reservoir hosts. Other zoonoses reservoirs include cattle, sheep, horses, pigs, cats, dogs, chickens, native birds like house sparrows, crows and ravens, Chimpanzee, Gorillas, Bank voles, Copepods, Fish, Foxes, Flies, Geese, Goats, Hamsters, Hyraxes, Lizards, Komodo dragon, Monkeys like the Macaque and Sooty mangabey, Opossums, Rabbits and hares, Raccoons, Sloths, Snails, Turtles, Whales, Wolves, masked civits, raccoon dogs, feret badgers, tortoises, and bats. Examples of natural reservoirs are: Field mice, for hantaviruses and Lassa fever Marmots, black rats, prairie dogs, chipmunks and squirrels for bubonic plague Armadillos and opossums for Chagas disease and several species of New World Leishmania Ticks for babesiosis and Rocky Mountain spotted fever Ground squirrels, porcupines, and chipmunks for Colorado tick fever Snails for schistosomiasis and swimmer's itch Pigs for cestode worm infections Raccoons, skunks, foxes and bats for rabies Shellfish for cholera Fowl (ducks and geese) for avian influenza Bats, the reservoir for Nipah and Hendra virus, rabies and severe acute respiratory syndrome(SARS) Dogs and wild canids for Leishmania infantum, the cause of infantile visceral leishmaniasis Cats, for Bartonella (aka Cat scratch disease) Gerbils for Leishmania major, the causative agent of cutaneous leishmaniasis in the Old World Rock hyrax for Leishmania aethiopica and, probably, certain strains of Leishmania tropica, the causative agents of cutaneous leishmaniasis in the Old World Mosquitoes, for malaria, West Nile virus, Yellow fever and Dengue fever The viruses carried in rodent reservoirs are transmitted when humans have contact with urine, fecal matter, saliva, or other body excretions from infected rodents. The viruses associated with arthropod vectors are spread most often when the vector mosquito, assassin bug, lice, flea, sandfly, blackfly, or tick bites a human, or when a human crushes a tick. Insects are responsible for spreading many diseases. Malaria is spread from person to person by certain species of female mosquito carrying the protozoan Plasmodium falciparum. The parasite enters the human host when an infected mosquito takes a blood meal. Bubonic plague (Black Death) is a bacterial disease of rodents caused by Yersinia pestis. It can be spread to humans and other animals by infected rat fleas. People usually get plague from being bitten by a rodent flea that is carrying the plague bacterium. However, some of these vectors may spread virus to animals, livestock, for example. Humans then become infected when they care for or slaughter the animals. Insects can also transmit pathogens to food; house flies are very good at spreading Salmonella and E.coli O157. They feed on fecal waste and transfer microbes from their feet and other body parts to food. The microbe does not invade or multiply inside the fly. Schistosomiasis, river blindness, and elephantiasis are not zoonotic, even though they may be transmitted by insects or use intermediate hosts vectors, because they depend on the human host for part of their life-cycle.

The World Health Organization (WHO) defines traditional medicine as: "Traditional medicine is the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness." In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside of its traditional culture, traditional medicine is often called complementary and alternative medicine. The WHO also notes, though, that "inappropriate use of traditional medicines or practices can have negative or dangerous effects" and that "further research is needed to ascertain the efficacy and safety" of several of the practices and medicinal plants used by traditional medicine systems. Core disciplines which study traditional medicine include herbalism, ethnomedicine, ethnobotany, and medical anthropology. Traditional medicine may include formalized aspects of folk medicine, i.e. longstanding remedies passed on and practiced by lay people. Practices known as traditional medicines include Ayurveda, Siddha medicine, Unani, ancient Iranian medicine, Irani, Islamic medicine, traditional Vietnamese medicine, traditional Chinese medicine, traditional Korean medicine, acupuncture, Muti, Ifá, traditional African medicine, and many other forms of healing practices. "Western medicine" is a term sometimes used to describe evidence-based medicine, which, for various historical reasons, emerged from "Western" civilisation (i.e. countries originally populated by or settled by Europeans), though it is now practised throughout the world. It involves the use of pharmacologically active agents or physical interventions to treat or suppress symptoms or pathophysiologic processes of diseases or conditions. Additionally the epistemological virtues of particular aspects of clinical trial methodology have been examined, mostly notably the special place that is given to randomisation,[13][14][15] the notion of a blind experiment and the use of a placebo control. Limitations of western medicine include dealing with: fibermyalgia, chronic pain, lower back pain, cancer, who gets an organ transplant, long waiting lists, creating superbugs, less strengthening of natural immunity, and potential awful side effects. Chiropractic is a form of alternative medicine[1] that emphasizes diagnosis, treatment and prevention of mechanical disorders of the musculoskeletal system, especially the spine, under the belief that these disorders affect general health via the nervous system.[2] Many chiropractors reject being characterized as complementary and alternative medicine (CAM).[3] It is a healthcare profession,[4] and although chiropractors have many similarities to primary care providers, they are more similar to a medical specialty like dentistry or podiatry.[5] The main chiropractic treatment technique involves manual therapy, especially manipulation of the spine, other joints, and soft tissues; treatment may also include exercises and health and lifestyle counseling.[6] Traditional chiropractic assumes that a vertebral subluxation or spinal joint dysfunction interferes with the body's function and its innate intelligence.[7] A large number of chiropractors want to separate themselves from the traditional vitalistic concept of innate intelligence.[4] Many studies of treatments used by chiropractors have been conducted, with conflicting results.[8] Systematic reviews of this research have not found evidence that chiropractic manipulation is effective, with the possible exception for the treatment of back pain.[9] A critical evaluation found that collectively, spinal manipulation was ineffective for any condition.[10] A Cochrane review found very low to moderate evidence that spinal manipulation therapy was no more effective than inert interventions, sham SMT or as an adjunct therapy for acute low back pain.[11] Spinal manipulation may be cost-effective for sub-acute or chronic low back pain but the results for acute low back pain were insufficient.[12] The efficacy and cost-effectiveness of maintenance chiropractic care are unknown.[13] The evidence suggests that spinal manipulation therapy is safe[14] but the rate of adverse events is unknown[15] as there is under-reporting.[16] It is frequently associated with mild to moderate adverse effects, with serious or fatal complications in rare cases.[15] There is controversy surrounding the level of risk of stroke from cervical manipulation.[17] It has been suggested that the relationship is causative,[18] but this is disputed by many chiropractors, who believe the association between chiropractic therapy and vertebrobasilar artery stroke is unproven.[19] Chiropractic is well established in the U.S., Canada and Australia.[20] It overlaps with other manualtherapy professions, including massage therapy, osteopathy, and physical therapy.[21] Back and neck pain are the specialties of chiropractic but many chiropractors treat ailments other than musculoskeletal issues.[9] Most who seek chiropractic care do so for low back pain.[22] D.D. Palmer founded chiropractic in the 1890s, and his son B.J. Palmer helped to expand it in the early 20th century.[23] It has two main groups: "straights", now the minority, emphasize vitalism, innate intelligence and spinal adjustments, and consider vertebral subluxations to be the cause of all disease; "mixers", the majority, are more open to mainstream views and conventional medical techniques, such as exercise, massage, and ice therapy.[4] Throughout its history, chiropractic has been controversial.[8][24] For most of its existence it has been at odds with mainstream medicine, sustained by pseudoscientific ideas such as subluxation and innate intelligence[25] that are not based on solid science.[9] Despite the general consensus of public health professionals regarding the benefits of vaccination, among chiropractors there are significant disagreements over the subject,[26] which has led to negative impacts on both public vaccination and mainstream acceptance of chiropractic.[27] The American Medical Association called chiropractic an "unscientific cult" in 1966[28] and boycotted it until losing an antitrust case in 1987.[29] Chiropractic has had a strong political base and sustained demand for services; in recent decades, it has gained more legitimacy and greater acceptance among medical physicians and health plans in the U.S.,[29] and evidence-based medicine has been used to review research studies and generate practice guidelines.[30] The practice remains at a crossroads between science and ideological dogma.[31] Herbalism ("herbology" or "herbal medicine") is use of plants for medicinal purposes, and the study of such use. Plants have been the basis for medical treatments through much of human history, and such traditional medicine is still widely practiced today. Modern medicine recognizes herbalism as a form of alternative medicine, as the practice of herbalism is not strictly based on evidence gathered using the scientific method. Modern medicine, does, however, make use of many plant-derived compounds as the basis for evidence-tested pharmaceutical drugs, and phytotherapy works to apply modern standards of effectiveness testing to herbs and medicines that are derived from natural sources. The scope of herbal medicine is sometimes extended to include fungal and bee products, as well as minerals, shells and certain animal parts. The World Health Organization (WHO) estimates that 80 percent of the population of some Asian and African countries presently use herbal medicine for some aspect of primary health care.[7] Pharmaceuticals are prohibitively expensive for most of the world's population, half of which lives on less than $2 U.S. per day.[8] In comparison, herbal medicines can be grown from seed or gathered from nature for little or no cost. Many of the pharmaceuticals currently available to physicians have a long history of use as herbal remedies, including opium, aspirin, digitalis, and quinine. According to the World Health Organization, approximately 25% of modern drugs used in the United States have been derived from plants.[9] At least 7,000 medical compounds in the modern pharmacopoeia are derived from plants[10] Among the 120 active compounds currently isolated from the higher plants and widely used in modern medicine today, 80 percent show a positive correlation between their modern therapeutic use and the traditional use of the plants from which they are derived. In a 2010 survey of the most common 1000 plant-derived compounds, only 156 had clinical trials published. Preclinical studies (tissue-culture and animal studies) were reported for about one-half of the plant products, while 12% of the plants, although available in the Western market, had "no substantial studies" of their properties. Strong evidence was found that 5 were toxic or allergenic, so that their use ought to be discouraged or forbidden. Nine plants had considerable evidence of therapeutic effect. The U.S. National Center for Complementary and Alternative Medicine of the National Institutes of Health funds clinical trials of the effectiveness of herbal medicines and provides “fact sheets” summarizing the effectiveness and side effects of many plant-derived preparations. Naturopathy, or naturopathic medicine, is a form of alternative medicine based on a belief in vitalism, which posits that a special energy called "vital energy" or "vital force" guides bodily processes such as metabolism, reproduction, growth, and adaptation. Naturopathy favors a holistic approach with non-invasive treatment and generally avoids the use of surgery and drugs. Practitioners of naturopathy often prefer methods of treatment that are not compatible with evidencebased medicine, and in doing so, reject the tenets of biomedicine and modern science. Naturopathic medicine is considered replete with pseudoscientific, ineffective, unethical, and possibly dangerous practices.[1] The term "naturopathy" is derived from Latin and Greek, and literally translates as "nature disease". Modern naturopathy grew out of the Natural Cure movement of Europe. The term was coined in 1895 by John Scheel and popularized by Benedict Lust, the "father of U.S. naturopathy". Beginning in the 1970s, there was a revival of interest in the United States and Canada, in conjunction with the holistic health movement. Today, naturopathy is primarily practiced in the United States and Canada. Naturopathy comprises many different treatment modalities, including nutritional and herbal medicine, lifestyle advice, counseling, flower essence, homeopathy and remedial massage. Much of the ideology and methodological underpinnings of naturopathy are in conflict with the paradigm of evidence-based medicine. Many naturopaths oppose vaccination based in part on the early views that shaped the profession. According to the American Cancer Society, "scientific evidence does not support claims that naturopathic medicine can cure cancer or any other disease, since virtually no studies on naturopathy as a whole have been published." Naturopaths aim to prevent illness through stress reduction and changes to diet and lifestyle, often rejecting the methods of evidence based medicine. Naturopaths do not generally recommend vaccines and antibiotics, based in part on the early views that shaped the profession, and they may provide alternative remedies even in cases where evidence-based medicine has been shown effective. Homeopathy is a system of alternative medicine created in 1796 by Samuel Hahnemann based on his doctrine of like cures like: a substance that causes the symptoms of a disease in healthy people will cure similar symptoms in sick people. Homeopathy is considered a pseudoscience, and its remedies have been found to be no more effective than placebos. Diseases have spiritual, as well as physical causes. Hahnemann believed the underlying causes of disease were phenomena that he termed miasms, and that homeopathic remedies addressed these. Medicines may cure symptoms, but the underlying imputed miasm still remains, and deep-seated ailments can be corrected only by removing the deeper disturbance of the vital force. The remedies are prepared by repeatedly diluting a chosen substance in alcohol or distilled water, Claims: dilution increases potency. The postulated mechanisms of action of homeopathic remedies are both scientifically implausible and not physically possible. Although some clinical trials produce positive results, systematic reviews reveal that this is because of chance, flawed research methods, and reporting bias. Continued homeopathic practice, despite the evidence that it does not work, has been criticized as unethical because it increases the suffering of patients by discouraging the use of real medicine, with the World Health Organisation warning against using homeopathy to try to treat severe diseases such as HIV and malaria. The continued practice, despite a lack of evidence of efficacy, has led to homeopathy being characterized within the scientific and medical communities as nonsense, quackery, or a sham. The British House of Commons Science and Technology Committee has stated: "In our view, the systematic reviews and meta-analyses conclusively demonstrate that homeopathic products perform no better than placebos. Acupuncture is the stimulation of specific acupoints along the skin of the body involving various methods such as penetration by thin needles or the application of heat, pressure, or laser light.[1] Traditional acupuncture involves needle insertion, moxibustion, and cupping therapy.[2] It is a form of complementary and alternative medicine[3] and a key component of traditional Chinese medicine (TCM).[4] According to TCM, stimulating specific acupuncture points corrects imbalances in the flow of qi through channels known as meridians.[5] Acupuncture aims to treat a range of conditions,[4] though is most commonly used for pain relief.[6][7] Acupuncture has been the subject of active scientific research, both in regard to its basis and therapeutic effectiveness, since the late 20th century.[8] Any evidence on the effectiveness of acupuncture is "variable and inconsistent" for all conditions.[9] An overview of high-quality Cochrane reviews suggested that acupuncture may alleviate some but not all kinds of pain,[10] while a systematic review of systematic reviews found little evidence that acupuncture is an effective treatment for reducing pain.[6] Although minimally invasive, the puncturing of the skin with acupuncture needles poses problems when designing trials that adequately control for placebo effects.[8][11] Some of the research results suggest acupuncture can alleviate pain but others consistently suggest that acupuncture's effects are mainly due to placebo.[12] A systematic review of systematic reviews highlighted recent high-quality randomized controlled trials which found that for reducing pain, real acupuncture was no better than sham acupuncture.[6] It remains unclear whether acupuncture reduces pain independent of a psychological impact of the needling ritual.[13] Acupuncture is generally safe when done using clean technique and single use needles.[2][14] When properly delivered, it has a low rate of mostly minor adverse effects.[1][2] Between 2000 and 2009, at least ninety-five cases of serious adverse events, including five deaths, were reported to have resulted from acupuncture.[6] Many of the serious events were reported from developed countries and many were due to malpractice.[6] Since serious adverse events continue to be reported, it is recommended that acupuncturists be trained sufficiently to reduce the risk.[6] A metaanalysis found that acupuncture for chronic low back pain was cost-effective as a complement to standard care, but not as a substitute for standard care except in cases where comorbid depression presented,[15] while a systematic review found insufficient evidence for the cost-effectiveness of acupuncture in the treatment of chronic low back pain.[16] Scientific investigation has not found any histological or physiological evidence for traditional Chinese concepts such as qi, meridians, and acupuncture points,[n 1][20][21] and some contemporary practitioners use acupuncture without following the traditional Chinese approach[22][23] and have abandoned the concepts of qi and meridians as pseudoscientific.[24][25] TCM is largely pseudoscience, with no valid mechanism of action for the majority of its treatments.[26] Acupuncture is currently used widely throughout China and many other countries, including the United States. MassageTherapy is the manipulation of superficial and deeper layers of muscle and connective tissue using various techniques, to enhance function, aid in the healing process, decrease muscle reflex activity, inhibit motor-neuron excitability,[1] promote relaxation and well-being. Massage involves working and acting on the body with pressure – structured, unstructured, stationary, or moving – tension, motion, or vibration, done manually or with mechanical aids. Target tissues may include muscles, tendons, ligaments, fascia, skin, joints, or other connective tissue, as well as lymphatic vessels, or organs of the gastrointestinal system. Massage can be applied with the hands, fingers, elbows, knees, forearm, or feet. The main professionals that provide therapeutic massage are massage therapists, athletic trainers, physical therapists and practitioners of many traditional Chinese and other eastern medicines. Massage practitioners work in a variety of medical settings and may travel to private residences or businesses. Contraindications to massage include deep vein thrombosis, bleeding disorders or taking blood thinners such as Warfarin, damaged blood vessels, weakened bones from cancer, osteoporosis, or fractures, bruising, and fever. Anyone suffering from these conditions should not use massage therapy. Aromatherapy is a form of alternative medicine that uses volatile plant materials, known as essential oils, and other aromatic compounds for the purpose of altering a person's mind, mood, cognitive function or health. Other stated uses include pain and anxiety reduction, enhancement of energy and short-term memory, relaxation, hair loss prevention, and reduction of eczema-induced itching.[11][12] Two basic mechanisms are offered to explain the purported effects. One is the influence of aroma on the brain, especially the limbic system through the olfactory system.[13] The other is the direct pharmacological effects of the essential oils.[14] While precise knowledge of the synergy between the body and aromatic oils is often claimed by aromatherapists, the efficacy of aromatherapy remains unproven. However, some preliminary clinical studies of aromatherapy in combination with other techniques show positive effects. Aromatherapy does not cure conditions, but it is suggested that it helps the body to find a natural way to cure itself and improve immune response. Some essential oils such as tea tree[1] have demonstrated anti-microbial effects, but there is still a lack of clinical evidence demonstrating efficacy against bacterial, fungal, or viral infections. Evidence for the efficacy of aromatherapy in treating medical conditions remains poor, with a particular lack of studies employing rigorous methodology,[2] but some evidence exists that essential oils may have therapeutic potential. Reflexology, or zone therapy, is an alternative medicine involving the physical act of applying pressure to the feet, hands, or ears with specific thumb, finger, and hand techniques without the use of oil or lotion. It is based on what reflexologists claim to be a system of zones and reflex areas that they say reflect an image of the body on the feet and hands, with the premise that such work affects a physical change to the body. The Reflexology Association of Canada defines reflexology as: "A natural healing art based on the principle that there are reflexes in the feet, hands and ears and their referral areas within zone related areas, which correspond to every part, gland and organ of the body. Through application of pressure on these reflexes without the use of tools, crèmes or lotions, the feet being the primary area of application, reflexology relieves tension, improves circulation and helps promote the natural function of the related areas of the body."[7] Reflexologists posit that the blockage of an energy field, invisible life force, or Qi, can prevent healing.[3] Another tenet of reflexology is the belief that practitioners can relieve stress and pain in other parts of the body through the manipulation of the feet. One claimed explanation is that the pressure received in the feet may send signals that 'balance' the nervous system or release chemicals such as endorphins that reduce stress and pain.[8] These hypotheses are rejected by the general medical community, who cite a lack of scientific evidence and the well-tested germ theory of disease.[4] Reflexology's claim to manipulate energy (Qi) has been highly controversial, as there is no scientific evidence for the existence of life energy (Qi), 'energy balance', 'crystalline structures,' or 'pathways' in the body A 2009 systematic review of randomised controlled trials concludes that "The best evidence available to date does not demonstrate convincingly that reflexology is an effective treatment for any medical condition."[2] There is no consensus among reflexologists on how reflexology is supposed to work; a unifying theme is the idea that areas on the foot correspond to areas of the body, and that by manipulating these one can improve health through one's qi.[3] Reflexologists divide the body into ten equal vertical zones, five on the right and five on the left.[4] Concerns have been raised by medical professionals that treating potentially serious illnesses with reflexology, which has no proven efficacy, could delay the seeking of appropriate medical treatment. Iridology (also known as iridodiagnosis[1] or iridiagnosis[2]) is an alternative medicine technique whose proponents claim that patterns, colors, and other characteristics of the iris can be examined to determine information about a patient's systemic health. Practitioners match their observations to iris charts, which divide the iris into zones that correspond to specific parts of the human body. Iridologists see the eyes as "windows" into the body's state of health. Iridologists believe they can use the charts to distinguish between healthy systems and organs in the body and those that are overactive, inflamed, or distressed. Iridologists believe this information demonstrates a patient's susceptibility towards certain illnesses, reflects past medical problems, or predicts later health problems. As opposed to evidence-based medicine, Iridology is not supported by quality research studies[3] and is widely considered pseudoscience.[4] Iris texture is a phenotypical feature which develops during gestation and remains without significant change after birth.[citation needed] The stability of iris structures is the foundation of the biometric technology which uses iris recognition for identification purposes.[5][6] In 1979, Bernard Jensen, a leading American iridologist and two other iridology proponents failed to establish the basis of their practice when they examined photographs of the eyes of 143 patients in an attempt to determine which ones had kidney impairments. Of the patients, forty-eight had been diagnosed with kidney disease, and the rest had normal kidney function. Based on their analysis of the patient's irises, the three iridologists could not detect which patients had kidney disease and which did not. T'ai chi or tai chi in English usage, is an internal Chinese martial art practised for both its defense training and its health benefits. It is also typically practised for a variety of other personal reasons: its hard and soft martial art technique, demonstration competitions, and longevity. T'ai chi's health training and meditation techniques concentrate on relieving the physical effects of stress on the body and mind. T'ai chi has been reported as being useful in treating a number of ailments, and is supported by a number of associations, including the National Parkinson Foundation and Diabetes Australia. However, medical evidence of effectiveness was lacking and in recent years research has been undertaken to address this.[2] A comprehensive overview of all the existing systematic reviews of t'ai chi ch'uan's health effects, found that as of 2011, "the evidence is conclusively or tentatively positive for fall prevention, general healthcare in older people, improving balance and enhancing psychological health"; the overview's authors thus recommended t'ai chi ch'uan to older people for its various physical and psychological benefits. There was no conclusive evidence of benefit for any of the other conditions researched, including Parkinson's disease, diabetes, cancer and arthritis. Yoga as exercise or alternative medicine is a modern phenomenon which has been influenced by the ancient Indian practice of hatha yoga. It involves holding stretches as a kind of low-impact physical exercise, and is often used for therapeutic purposes.[1][2][3] Yoga in this sense often occurs in a class and may involve meditation, imagery, breath work and music.[4][5] Both the meditative and the exercise components of hatha yoga have been researched for both specific and non-specific health benefits. Hatha yoga has been studied as an intervention for many conditions, including back pain, stress, and depression. In general, it can help improve quality of life, but does not treat disease.[6] A survey released in December 2008 by the US National Center for Complementary and Alternative Medicine[7] found that hatha yoga was the sixth most commonly used alternative therapy in the United States during 2007, with 6.1 percent of the population participating. Yoga is a core component of the Mindfulness-based stress reduction (MBSR) program. Drawing from recent research on the mental and physical benefits of practicing yoga, positive psychologists have begun to look deeper into the possibilities of utilizing yoga to improve life for people even in the absence of disease. A dietary supplement is intended to provide nutrients that may otherwise not be consumed in sufficient quantities. Supplements as generally understood include vitamins, minerals, fiber, fatty acids, or amino acids, among other substances. U.S. authorities define dietary supplements as foods, while elsewhere they may be classified as drugs or other products. There are more than 50,000 dietary supplements available. More than half of the U.S. adult population (53% - 55%) consume dietary supplements with most common ones being multivitamins.[1][2] These products are not intended to prevent or treat any disease and in some circumstances are dangerous, according to the U.S. National Institutes of Health. For those who fail to consume a balanced diet, the agency says that certain supplements "may have value."[3] Most supplements should be avoided, and usually people should not eat micronutrients except people with clearly shown deficiency because many are a waste of money. Some vitamins are fat soluble so they are not absorbed unless eaten with lipids. Most excess vitamins are eliminated by the body, making expensive urine. People should first consult a doctor before taking supplements. An exception is vitamin D, which is recommended in Nordic countries[6] due to weak sunlight. Placebo-controlled studies are a way of testing a medical therapy in which, in addition to a group of subjects that receives the treatment to be evaluated, a separate control group receives a sham "placebo" treatment which is specifically designed to have no real effect. Placebos are most commonly used in blinded trials, where subjects do not know whether they are receiving real or placebo treatment. Often, there is also a further "natural history" group that does not receive any treatment at all. The purpose of the placebo group is to account for the placebo effect, that is, effects from treatment that do not depend on the treatment itself. Such factors include knowing one is receiving a treatment, attention from health care professionals, and the expectations of a treatment's effectiveness by those running the research study. Without a placebo group to compare against, it is not possible to know whether the treatment itself had any effect. Patients frequently show improvement even when given a sham or "fake" treatment. Such intentionally inert placebo treatments can take many forms, such as a pill containing only sugar, a surgery where nothing efficacious is actually done (just an incision and sometimes some minor touching or handling of the underlying structures), or a medical device (such as an ultrasound machine) that is not actually turned on. Also, due to the body's natural healing ability and statistical effects such as regression to the mean, many patients will get better even when given no treatment at all. Thus, the relevant question when assessing a treatment is not "does the treatment work?" but "does the treatment work better than a placebo treatment, or no treatment at all?" As one early clinical trial researcher wrote, "the first object of a therapeutic trial is to discover whether the patients who receive the treatment under investigation are cured more rapidly, more completely or more frequently, than they would have been without it."[1]p.195 More broadly, the aim of a clinical trial is to determine what treatments, delivered in what circumstances, to which patients, in what conditions, are the most effective.[2][3] Therefore, the use of placebos is a standard control component of most clinical trials, which attempt to make some sort of quantitative assessment of the efficacy of medicinal drugs or treatments. Such a test or clinical trial is called a placebo-controlled study, and its control is of the negative type. A study whose control is a previously tested treatment, rather than no treatment, is called a positivecontrol study, because its control is of the positive type. Government regulatory agencies approve new drugs only after tests establish not only that patients respond to them, but also that their effect is greater than that of a placebo (by way of affecting more patients, by affecting responders more strongly, or both). As a result, "placebo-controlled studies often are designed in such a way that disadvantages the placebo condition" Home birthing in developed countries is attended or an unattended childbirth in a non-clinical setting, typically using natural childbirth methods, that takes place in a residence rather than in a hospital or a birth centre, and usually attended by a midwife or lay attendant with experience in managing home births. Home birth was, until the advent of modern medicine, the de facto method of delivery. Since the beginning of the 20th century, home birth rates have drastically fallen in most developed countries, generally to less than 1% of all births. Infant and mother mortality rates have also dropped drastically over the same time period. Women with access to high-quality medical care may choose home birth because they prefer the intimacy of a home and family-centered experience or desire to avoid a medically-centered experience typical of a hospital. Professionals attending home births can be obstetricians, certified or uncertified midwives, and doulas. In developing countries, where women may not be able to afford medical care or it may not be accessible to them, a home birth may be the only option available, and the woman may or may not be assisted by a professional attendant of any kind. Multiple studies have been performed concerning the safety of home births for both the child and the mother; as standard practices, licensing requirements, and access to emergency hospital care differs between regions it can be difficult to compare studies across national borders. A 2014 US survey of medical studies found that perinatal mortality rates were triple that of hospital births, and a US nation-wide study over 13 million births on a 3-year span (2007-2010) found that births at home were roughly 10 times as likely to be stillborn (14 times in first-born babies) and almost four times as likely to have neonatal seizures or serious neurological dysfunction when compared to babies born in hospitals, while a 2007 UK survey found that perinatal mortality rates were only slightly higher in that country than planned hospital births for low-risk pregnancies. Both baby's and mother's higher mortalities are associated with the inability to timely assist mothers with emergency procedures in case of complications during labour. Blood transfusion is generally the process of receiving blood products into one's circulation intravenously. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors, and platelets. Units of packed red blood cells are typically only recommended when either a patient's hemoglobin level falls below 10 g/dL or hematocrit falls below 30%; recently, this 'trigger' level has been decreased to 7-8 g/dL, as a more restrictive strategy has been shown to have better patient outcomes.[1] This is in part due to the increasing evidence that there are cases where patients have worse outcomes when transfused.[2] One may consider transfusion for people with symptoms of cardiovascular disease such as chest pain or shortness of breath.[1] Globally around 85 million units of red blood cells are transfused in a given year Objections to blood transfusions may arise for personal, medical, or religious reasons. For example, Jehovah's Witnesses object to blood transfusion primarily on religious grounds—they believe that blood is sacred, as the Bible says "abstain from blood" (Acts 15:28,29). They have also highlighted complications associated with transfusion. Organ donation is the donation of biological tissue or an organ of the human body, from a living or dead person to a living recipient in need of a transplantation. Transplantable organs and tissues are removed in a surgical procedure following a determination, based on the donor's medical and social history, of which are suitable for transplantation. While views of organ donation are positive there is a large gap between the numbers of registered donors compared to those awaiting organ donations on a global level. Certain groups, like the Roma (gypsies), oppose organ donation on religious grounds, but most of the world's religions support donation as a charitable act of great benefit to the community.[40] Issues surrounding patient autonomy, living wills, and guardianship make it nearly impossible for involuntary organ donation to occur. The primary issues surrounding the morality of organ donation are semantical in nature. The debate over the definitions of life, death, human, and body is ongoing. For example, whether or not a braindead patient ought to be kept artificially animate in order to preserve organs for procurement is an ongoing problem in clinical bioethics. In addition, some have argued that organ donation constitutes an act of self-harm, even when an organ is donated willingly. Further, the use of cloning to produce organs with an identical genotype to the recipient has issues all its own. Cloning is still a controversial topic, especially considering the possibility for an entire person to be brought into being with the express purpose of being destroyed for organ procurement. While the benefit of such a cloned organ would be a zero-percent chance of transplant rejection, the ethical issues involved with creating and killing a clone may outweigh these benefits. However, it may be possible in the future to use cloned stem-cells to grow a new organ without creating a new human being. A relatively new field of transplantation has reinvigorated the debate. Xenotransplantation, or the transfer of animal (usually pig) organs into human bodies, promises to eliminate many of the ethical issues, while creating many of its own.[citation needed] While xenotransplantation promises to increase the supply of organs considerably, the threat of organ transplant rejection and the risk of xenozoonosis(animal diseases becoming human diseases), coupled with general anathema to the idea, decreases the functionality of the technique. Some animal rights groups oppose the sacrifice of an animal for organ donation and have launched campaigns to ban them. the moral status of "black market organ donation" relies upon the ends, rather than the means.[citation needed] In so far as those who donate organs are often impoverished[citation needed] and those who can afford black market organs are typically well-off,[citation needed] it would appear that there is an imbalance in the trade. In many cases, those in need of organs are put on waiting lists for legal organs for indeterminate lengths of time — many die while still on a waiting list. Organ donation is fast becoming an important bioethical issue from a social perspective as well. While most first-world nations have a legal system of oversight for organ transplantation, the fact remains that demand far outstrips supply. Consequently, there has arisen a black market trend often referred to as transplant tourism.[citation needed] The issues are weighty and controversial. On the one hand are those who contend that those who can afford to buy organs are exploiting those who are desperate enough to sell their organs. Many suggest this results in a growing inequality of status between the rich and the poor. On the other hand are those who contend that the desperate should be allowed to sell their organs and that preventing them from doing so is merely contributing to their status as impoverished. An autopsy — also known as a post-mortem examination, necropsy (particularly as to nonhuman bodies), autopsia cadaverum, or obduction — is a highly specialized surgical procedure that consists of a thorough examination of a corpse to determine the cause and manner of death and to evaluate any disease or injury that may be present. It is usually performed by a specialized medical doctor called a pathologist. Some religions including Judaism and Islam usually discourage the performing of autopsies on their adherents. They outright object, because bodily intrusion violates beliefs about the sanctity of keeping the human body complete. Organizations such as Zaka in Israel and Misaskim in the USA generally guide families how to ensure that an unnecessary autopsy is not made. Refusal of medical assistance is the term for when a patient refuses any or all parts of medical treatment. Informed refusal is linked to the informed consent process, as a patient has a right to consent, but also may choose to refuse.[3] The individual needs to be in possession of the relevant facts as well as of his reasoning faculties, such as not being intellectually disabled or mentally ill and without an impairment of judgment at the time of refusing. Such impairments might include illness, intoxication, drunkenness, using drugs, insufficient sleep, and other health problems.[2] In cases where an individual is considered unable to give informed refusal, another person (guardian) may be authorized to give consent on their behalf. The pregnant patient represents a specific dilemma in the field of informed refusal as her action may result in harm or death to the fetus. Ethicists disagree on how to handle this situation. Christian Science is a set of beliefs and practices including that sickness is an illusion that can be corrected by prayer alone, believing that reality is purely spiritual and the material world an illusion. This includes the view that disease is a mental rather than physical disorder, that there is no death, and that the sick should be treated, not by medicine, but by a form of prayer that seeks to correct the beliefs responsible for the illusion of ill health.[10] The church does not require that Christian Scientists avoid all medicine – adherents use dentists, optometrists, obstetricians, physicians for broken bones, and vaccination when required by law – but maintains that Christian Science prayer is most effective when not combined with medical care.[11] The avoidance of medical treatment was blamed for the deaths of several adherents and their children; parents and others were prosecuted for manslaughter or neglect and in a few cases convicted. Euthanasia refers to the practice of intentionally ending a life in order to relieve pain and suffering. In some countries there is a divisive public controversy over the moral, ethical, and legal issues of euthanasia. Those who are against euthanasia may argue for the sanctity of life, while proponents of euthanasia rights emphasize alleviating suffering, bodily integrity, self-determination, and personal autonomy.[6] Jurisdictions where euthanasia or assisted suicide is legal include the Netherlands, Belgium, Luxembourg, Switzerland, Estonia, Albania, the US states of Washington, Oregon and Montana,[7] and, starting in 2015, the Canadian Province of Quebec. The difficulty of justifying euthanasia when faced with the notion of the subject's "right to life". Euthanasia may be classified according to whether a person gives informed consent into three types: voluntary, non-voluntary and involuntary.[24][25] There is a debate within the medical and bioethics literature about whether or not the non-voluntary (and by extension, involuntary) killing of patients can be regarded as euthanasia, irrespective of intent or the patient's circumstances. However, others see consent as essential: Euthanasia has to be voluntary, and that "involuntary euthanasia is, as such, a great wrong". When the patient brings about his or her own death with the assistance of a physician, the term assisted suicide is often used instead. Assisted suicide is legal in Switzerland and the U.S. states of Oregon, Washington and Montana. The "right to die" is often understood to mean that a person with a terminal illness should be allowed to commit suicide or assisted suicide or to decline life-prolonging treatment, where a disease would otherwise prolong their suffering to an identical result. The question of who, if anyone, should be empowered to make these decisions is often central to debate.The right to die is sometimes associated with the idea that one's body and one's life are one's own, to dispose of as one sees fit. However, a legitimate state interest in preventing irrational suicides is sometimes argued. A debate exists within bioethics over whether the right to die is universal, only applies under certain circumstances—such as terminal illness, or if it exists at all. Hinduism accepts the right to die for those who are tormented by terminal diseases or those who have no desire, ambition or no responsibilities remaining; and allows death through the non-violent practice of fasting to the point of starvation (Prayopavesa).[2] Jainism has a similar practice named Santhara. Other religious views on suicide vary in their tolerance, and include denial of the right as well as condemnation of the act. In the Catholic faith, suicide is considered a grave sin. Japanese health insurance will even pay out to families of suicides because it is a traditionally honorable way to die. Withholding or withdrawing life-sustaining treatments with patient consent (voluntary) is almost unanimously considered, at least in the United States, to be legal.[58] The use of pain medication in order to relieve suffering, even if it hastens death, has been held as legal in several court decisions.[56] Some governments around the world have legalized voluntary euthanasia but generally it remains as a criminal homicide. In the Netherlands and Belgium, where euthanasia has been legalized, it still remains homicide although it is not prosecuted and not punishable if the perpetrator (the doctor) meets certain legal exceptions. On Monday, Eva went to the emergency room following a fall from her bike. Fortunately, her only broken bone was a fi nger. But she suffered scrapes and cuts, including some deep cuts on her legs. After spending several hours in the emergency room having her wounds cleaned, stitched, and bandaged, Eva returned home. Tuesday morning, one of the deeper cuts on Eva’s legs was red and felt warm. She had a few pills of an antibiotic left over from her bout with strep throat that previous winter. Thinking it might help to prevent infection, she took them according to the prescription instructions. Throughout Tuesday, the cut on Eva’s leg became increasingly red, swollen, and painful. Eva felt awful and returned to the hospital on Tuesday night. Her cut had become infected. The doctors cleaned and restitched her leg and prescribed a daily dose of Antibiotic A, a stronger version of the same antibiotic Eva had taken at home just that morning. By Thursday, Eva’s infection had spread to the point where it was too painful to walk. In addition, Eva felt ill. She returned to the hospital and this time was admitted. The doctors immediately administered a different kind of antibiotic, Antibiotic C, directly into Eva’s bloodstream through an intravenous tube. Friday, Eva felt better, and her leg became less painful and swollen. But on Saturday, it was clear that Eva had taken a turn for the worse. The infection on her leg continued to spread, and she had become feverish. The medical staff involved with Eva’s case held a meeting to plan the next steps in Eva’s treatment. GOING FURTHER: Identify the Genes Carrying Antibiotic Resistance WELL NUMBER SAMPLE 1 2 3 4 5 6 DNA size marker Monday, immediately after arriving at the hospital Monday evening, just before leaving the hospital Tuesday night after returning to the hospital Thursday evening, after being admitted to the hospital Saturday morning In bacteria, the genes for antibiotic resistance are often carried on plasmids (small circles of DNA) rather than in the main bacterial chromosomal DNA. Plasmid DNA can be prepared and viewed using gel electrophoresis. Dr. Hincapie wanted to determine which gene was responsible for the antibiotic resistance he observed in the bacteria causing Eva’s infection. First, he isolated plasmid DNA from each of Eva’s original samples. Then, he separated the plasmid DNA samples using gel electrophoresis. Here’s a photograph of his gel. Dr. Hincapie recognized that the two larger pieces of DNA— 2100 base pairs and 1800 base pairs—were from plasmids found in bacteria that cause infections. The brightness of a piece of DNA on a gel reveals two things: larger pieces of DNA are brighter than smaller pieces and larger amounts of DNA appear brighter than smaller amounts. Knowing this, which bands on this gel do you think contain a gene for resistance to: Antibiotic A: Antibiotic B: Antibiotic C: Antibiotic D: 1 2 WELL NUMBER 3 4 5 6 IMMUNE SYSTEM Matching Write the best match letter on your answer sheet. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.

ELISA and Western blot tests for AIDS Angiography is a test used to detect blockages of the arteries or veins. A cerebral angiogram can detect the degree of narrowing or obstruction of an artery or blood vessel in the brain, head, or neck. It is used to diagnose stroke and to determine the location and size of a brain tumor, aneurysm, or vascular malformation. This test is usually performed in a hospital outpatient setting and takes up to 3 hours, followed by a 6- to 8-hour resting period. The patient, wearing a hospital or imaging gown, lies on a table that is wheeled into the imaging area. While the patient is awake, a physician anesthetizes a small area of the leg near the groin and then inserts a catheter into a major artery located there. The catheter is threaded through the body and into an artery in the neck. Once the catheter is in place, the needle is removed and a guide wire is inserted. A small capsule containing a radiopaque dye (one that is highlighted on x-rays) is passed over the guide wire to the site of release. The dye is released and travels through the bloodstream into the head and neck. A series of x-rays is taken and any obstruction is noted. Patients may feel a warm to hot sensation or slight discomfort as the dye is released.

brain at work, a long list of inventions and innovations have changed medicine. Use these to make your Timeline of Milestones of Medical Tech. 1668 Microscope Dr. Antony Van Leeuwenhoek, a Dutch draper and scientist, and one of the pioneers of microscopy who in the late 17th century became the first man to make and use a real microscope. 1798 Vaccination Edward Jenner invents the world's first vaccine against the deadly disease, smallpox Dec. 31, 1815 Stethoscope René Laënnec, a French physician, invented the stethoscope, a trumpet-shaped wooden tube, to examine a woman whose heart he could not hear by pressing his ear to her chest. Dec. 31, 1841 Anesthesia Dr. Crawford W. Long performed the first operation using diethyl ether as an anesthetic. He pressed an ether-soaked towel against the patient's face to put him to sleep, then removed one of two tumors from his neck. He billed the patient $2, itemizing the cost of the ether as well as the operation. 1862 Pasteurization The process is named after Louis Pasteur. He was the first person to learn how to do it successfully. The first pasteurization was done by Louis Pasteur and Claude Bernard on April 20, 1862. It is a process of heating food, which is usually a liquid, to a specific temperature for a predefined length of time and then immediately cooling it after it is removed from the heat. This process slows spoilage caused by microbial growth in the food. 1865 Antiseptic Joseph Lister was instrumental in developing practical applications of the germ theory of disease with respect to sanitation in medical settings and aseptic surgical techniques—partly through the use of carbolic acid (phenol) as an antiseptic. 1873 Compound Microscope Resolution Ernst Abbe worked out the solution to the blurry compound microscope problem in the 1870's. He determined the physical laws that govern the collection of light by an objective and maximised this collection by using water and oil immersion lenses. (viewing of pathogens) Dec. 31, 1874 Brain Waves Using a galvanometer, the British scientist Richard Caton noted electrical impulses from the brains of animals, laying down the principles that would lead to the development of the electroencephalogram, or EEG. 1895 X-Ray Wilhelm Conrad Röntgen, a German physicist, discovered the X-ray, an invention so remarkable that many did not believe the first reports of its use. The New York Times referred to it mockingly as Dr. Röntgen's "alleged discovery of how to photograph the invisible." 1903 Electrocardiogram Dr. Willem Einthoven of the Netherlands invented the first practical electrocardiogram. The original weighed 600 pounds, had a water cooling system for its gigantic electromagnets and needed five operators. In 1924 he received the Nobel Prize in Physiology or Medicine for his invention. 1910 Laparoscopy Dr. Hans Christian Jacobaeus, a Swedish internist, performed the first laparoscopy on a human. He punctured the abdominal walls of 17 patients, using cocaine as a local anesthetic, and removed fluid from their abdomens. After removing the fluid, he examined the cavities with a cytoscope. 1924 Electroencephalogram Dr. Hans Berger of Germany recorded the first human electroencephalogram, or EEG. His assertion that the brain's electrical impulses could be recorded was generally met with derision, and five years passed before Dr. Berger published his technique for recording the electrical activity of the human brain from the surface of the head. 1931 Electron Microscope The invention of the electron microscope by Max Knoll and Ernst Ruska at the Berlin Technische Hochschule in 1931 finally overcame the barrier to higher resolution that had been imposed by the limitations of visible light. The electron microscope allowed us to view viruses, pathogens of many human diseases 1936 Pacemaker Dr. Albert S. Hyman demonstrated a heart pacemaker. The device was about 10 inches long and weighed less than a pound; it supplied the heart with a current with adjustable voltage. The device, Dr. Hyman said, had been used in seven cases, although the results were good in only two of them. 1943 Dialysis Willem J. Kolff, a Dutch physician, built the first dialysis machine, working with tin cans and parts from washing machines during the Nazi occupation of the Netherlands. Although his first few attempts were failures, Dr. Kolff did finally develop a useful machine in the 1950s while working with colleagues at the Cleveland Clinic. 1947 Cardiac Defibrillation A Cleveland cardiovascular surgeon, Claude Beck, successfully defibrillated the heart of a 14-year-old boy during cardiac surgery, bringing an apparently dead person back to life. Although the principle of defibrillation had been known for decades, this was probably its first successful clinical application. 1952 Mechanical Heart Henry Opitek, 41, was operated on using an artificial heart, the Dodrill GMR heart machine, manufactured by General Motors and generally considered the first mechanical heart. The surgeon, Dr. Forest Dewey Dodrill, successfully repaired the patient's mitral valve, and Mr. Opitek lived until 1981. 1952 Magnetic Resonance The Nobel Prize in Physics was awarded to Felix Bloch and Edward Mills Purcell for their work in developing nuclear magnetic resonance, the principle behind M.R.I. machines. 1953 Heart-Lung Bypass Dr. John Heysham Gibbon used his new invention, the heart-lung bypass machine, for the first time in open-heart surgery, supporting a patient's heart and lung functions for about half the time of the surgery. It was the culmination of his decades of work in developing the machine. 1954 Kidney Transplant In the first successful kidney transplant, after at least nine failures, a team of surgeons at Peter Bent Brigham Hospital in Boston transplanted a kidney from a 24-year-old man to his twin brother. The recipient lived 11 years more, and in 1990 the lead surgeon, Dr. Joseph E. Murray, won the Nobel Prize in Medicine or Physiology. 1958 Pacemaker Dr. Seymour Furman, a cardiologist at Montefiore Hospital in the Bronx, succeeded in extending a patient's life by more than two months using a cardiac pacemaker, a large machine to which the patient was attached by a 50-foot extension cord. By the next year, portable versions of the machine were in use. Fetal Ultrasound Dr. Edward Hon of Yale reported using a Doppler monitor on a woman's abdomen to detect fetal heartbeat. Ultrasound's principles had been known for more than a century (a Swedish physicist, Christian Andreas Doppler, gave his name to the phenomenon in 1842), but this was its first use in prenatal care. 1961 Minimally Invasive Surgery Dr. Thomas J. Fogarty came up with the idea for the balloon embolectomy catheter for removing blood clots, and used it on a patient six weeks later. It was the first minimally invasive surgery technique. 1963 Artificial Heart Paul Winchell, the ventriloquist and inventor, patented the first artificial heart, developed in collaboration with Dr. Henry J. Heimlich, later famous for the Heimlich maneuver. Liver Transplant The first human liver transplant was performed by Dr. Thomas E. Starzl. The patient, a 3-year-old child, rapidly bled to death. 1965 Portable Defibrillator Dr. Frank Pantridge installed the first portable defibrillator in an ambulance in Belfast, Northern Ireland. It weighed 150 pounds and was powered by car batteries. Commercial Ultrasound Walter Erich Krause of the Siemens Corporation filed a patent for the first practical commercial ultrasound machine. According to the patent, his machine could be "used for practical ultra-sonic-optical examination to achieve a lifelike reproduction of the body part under examination." 1967 Heart Transplant Dr. Christiaan Barnard, performed the first human heart transplant. The patient, a 53-year-old man, died 18 days later. 1971 CT Scanner The first commercial CT scanner, developed by Dr. Godfrey Hounsfield, was used on a patient in London. Dr. Hounsfield shared the 1979 Nobel Prize in Physiology or Medicine for his invention. 1973 Insulin Pump An inventor and entrepreneur, Dean L. Kamen, patented the first insulin pump. He became perhaps even better known for a later invention, the Segway transporter. 1978 M.R.I. Dr. Raymond V. Damadian announced that he had patented a technique using nuclear magnetic resonance to distinguish between normal and cancerous tissue. In 2003, two other researchers won a Nobel Prize for further discoveries. 1989 Synthetic Blood The first synthetic blood, Fluosol-DA, was approved for human use. It was withdrawn from the market in 1994. The search for a blood substitute goes on, and there is none in use in clinical practice. 1992 DNA Sequencing Dr. Leroy E. Hood patents his invention of the automated DNA sequencing technique. The patent is owned by the California Institute of Technology. Imaging Thought A paper in the journal Magnetic Resonance Medicine by a group of researchers at the Medical College of Wisconsin announced the first use of functional magnetic resonance imaging to detect brain blood flow in conjunction with a human mental activity. 2000 Human Genome The first draft of the human genome was announced. Three years later, it was declared complete three years later. 2004 Adaptive Artificial Knee The Rheo knee, a plastic prosthetic joint that adapts to a user's walking style and changes in terrain, was produced by the Ossur Corporation. 2006 Artificial Liver Dr. Colin McGucklin and Dr. Nico Forraz of Newcastle University developed a liver grown from stem cells. The size of a small coin, it was not an organ that could be implanted in a human. Nervous systems COMPLETlON l. The part of the brain that controls balance is the 2.

Preventing Food Contamination and Food Bourne Illness Wash hands the right way—for 20 seconds with soap and running water. Be sure to scrub the backs of your hands, between your fingers, and under your nails. Wash surfaces and utensils after each use. Rinsing utensils, countertops, and cutting boards with water won’t do enough to stop bacteria from spreading. Clean utensils and small cutting boards with hot, soapy water. Clean surfaces and cutting boards with a bleach solution. Wash fruits and veggies—but not meat, poultry, or eggs. Even if you plan to peel fruits and veggies, it’s important to wash them first because bacteria can spread from the outside to the inside as you cut or peel them. Don't cross-contaminate: Use separate cutting boards, plates, and utensils for raw (uncooked) produce and for raw (uncooked) meat, poultry, seafood, and eggs. Cook to the right temperature: While many people think they can tell when food is “done” simply by checking its color and texture, Use a food thermometer. Make sure food reaches its safe minimum cooking temperature. For example, internal temperatures should be 145°F for whole meats (allowing the meat to rest for 3 minutes before carving or eating), 160°F for ground meats, and 165°F for all poultry. Eggs should be cooked until the yolk is firm. Microwave food thoroughly (to 165 ˚F). During meal times, while food is being served and eaten, keep it hot (at 140 ˚F or above). After meals are over, refrigerate leftover food quickly. Refrigerate the foods that tend to spoil more quickly (like fruits and vegetables, milk, eggs, and meats) within two hours. Warm foods will chill faster if they are divided into several clean, shallow containers. Thaw or marinate foods in the refrigerator, never on the counter or in the kitchen sink. Know when to throw food out.

Has anyone actually seen this happen or is it an urban legend? Are we talking about a Yugo here or a 1956 Caddy? Let me know soon, Unca Cecil--I'm trying to walk more these days, and if I get run over I need to know whether to call mom or a tow truck. — Eric Rapp, Los Angeles Always smart to be prepared, Eric. I haven't gotten to the bottom of this yet, but my interim judgment is: (1) This sure sounds like an urban legend. (2) But maybe it's not. I just got off the phone with a woman who lifted, if not an entire car, at least a nontrivial fraction of the weight of one off her trapped son. The woman's name is Angela Cavallo, and she still lives in Lawrenceville, Georgia, where the incident happened on April 9, 1982. (An Associated Press account didn't appear till April 14, but Angela remembers the date because it was Good Friday.) Her then-teenage son Tony had a 1964 Chevy Impala jacked up in the driveway--he'd removed a rear tire and was working on the suspension. A neighbor kid came to the kitchen door to tell Angela there'd been an accident. She rushed out to find Tony pinned under the car--something had been stuck and in trying to loosen it he'd rocked the car off the jack. Now he was caught in one of the rear wheel wells; all she could see of him was from the waist down. Ancient Chevies being big ol' cars with a lot of room around the wheels, Tony wasn't immediately crushed. But he was out cold. Hollering to the neighbor kid to get help, Angela grabbed the side of the car with both hands and pulled up with all her strength. The AP account said she raised the car four inches; she doubts it was that much but believes it was enough to take the pressure off. She recalls nothing about the rescue, but the AP said two neighbors reinserted the jack and dragged the boy out. (Tony recovered OK.) Angela, then in her late 50s, guesses she kept the car propped up for five minutes. She describes herself as 5-foot-8, large-framed and strong, but figures she couldn't have picked the car up under normal circumstances, attributing her feat to adrenaline. (Thanks to journalist Mariana Minaya for providing the AP story.) Some may quibble that lifting a car a couple inches is hardly the same as picking it up. A doctor friend says an adrenaline rush (norepinephrine rush, whatever) wouldn't last five minutes and suggests what we're seeing here wasn't so much superhuman strength as endurance in the face of otherwise overwhelming pain. Maybe; my point is, car-lifting stories have a basis in fact. I've got a line on a couple similar tales but no details yet. In the meantime, a few other tidbits: Laurence Gonzales, in Deep Survival: Who Lives, Who Dies, and Why(2003), writes, "On Mother's Day 1999, Saint John Eberle and his partner, Marc Beverly, were climbing in New Mexico's Sandia Mountain Wilderness when a rock weighing more than 500 pounds fell on Eberle, pinning him. Beverly watched as Eberle lifted the rock off of himself." Gonzales tells me he got this story from an annual summary entitled Accidents in North American Mountaineering. I'm trying to reach the men for more details. From Ikai and Steinhaus, "Some Factors Modifying the Expression of Human Strength," Journal of Applied Physiology, 1961, we learn the following: "The maximal pull of forearm flexors was increased and, in some instances, decreased in predictable fashion by a loud noise, by the subject's own outcry, by certain pharmacologic agents (alcohol, adrenaline, and amphetamine), and by hypnosis. Significant average changes ranging from +26.5% to 31% were observed." The authors suggest that the normal human inability to exert oneself to one's physiological maximum is the result of "acquired inhibitions that in turn are subject to disinhibition by pure Pavlovian procedures, by anesthetization of inhibitory mechanisms, or by pharmacologically induced symptoms serving as stimuli for disinhibition." In other words, you're always capable of great feats; it just takes a crisis for you to actually perform them. In a 1990 interview the late comic book artist Jack Kirby said he created the Incredible Hulk after seeing a mom lift a car off a kid. However, Kirby's former assistant Mark Evanier doubts the story, saying Kirby never mentioned it privately. Let it not be said the Straight Dope suppresses negative results. — Cecil Adams
