Gender Age Smoking Nutrition 101 - Objectives Understanding of basic nutrients Recommended daily allowances Nutrition labels Resources What is a healthy diet? Recommendations for a healthy diet from the 2005 Dietary Guidelines include consuming a variety of nutrient-dense foods and beverages within and among the basic food groups while choosing foods that limit the intake of saturated and trans fat, cholesterol, added sugars, salt, and alcohol. Why do we need a healthy diet? Provide energy Contribute to growth of tissues Regulate body processes Prevent deficiency and degenerative disease Where do we start? Create Balance Balance is created by meeting recommended daily intake requirements within energy needs by adopting a balanced eating pattern as suggested in the USDA’s MyPyramid Food Guidance System. You can utilize www.mypyramid.gov to create your own individualized plan! Balance can only truly be obtained by understanding the nutrients you take into your body. Part I Basic Nutrient Review Essential Nutrients Essential nutrients refer to nutrients that must be obtained from dietary intake – they are not made by the body. The 6 nutrients that are classified as essential to the body are carbohydrates, proteins, fats, vitamins, minerals and water. Macronutrients Carbohydrates, proteins and fats are classified as macronutrients. This is because these three nutrients have caloric value, meaning they provide energy, and the body requires a large quantity of these nutrients on a daily basis. Micronutrients Vitamins and minerals are classified as micronutrients. These nutrients are needed in only small amounts and do not have caloric value. Water Water is in a class by itself. The body requires large amounts on a daily basis. Water does not have caloric value, therefore, it does not provide energy. Carbohydrates Carbohydrates are the body’s primary source of fuel (4 calories per gram) for all physical activity. Carbohydrates can be found in a variety of foods including grains, fruits, vegetables, and the milk/alternative group (soy, rice, nut, and other nondairy products). Good and Bad Carbs??? In recent nutritional history, carbs have been labeled as either good or bad. Good carbs are from less processed sources (fruits, vegetable, whole grains), thus, they are nutrient dense and a good source of energy. Bad carbs are from processed foods (sugars, white flour, etc) and are nutrient poor, meaning their calories are from sugars and other sources that are classified as discretionary. Proteins Proteins are necessary for development, growth, and repair of the body. Protein has a caloric value of 4 calories per gram. However, it is not an efficient source of energy for the body. If the body is relying on protein for energy, the body is breaking down its own muscle and this is not a good thing Proteins Proteins are found in a variety of foods including grains and vegetables, but are mainly concentrated in dairy, meat and beans. Animal sources of protein are complete proteins – they contain all of the essential proteins that cannot be manufactured by the body. Proteins With the exception of soy, plant-based sources of protein are incomplete protein sources – they do not contain all of the body’s essential proteins. Groups of plant-based proteins should be paired together to form complete proteins – grains with nuts, or vegetables with seeds. This is a critical aspect of nutrition for individuals who consume a vegetarian diet. Fats Fats are a concentrated source of energy – 9 calories per gram. Fat is primarily used as fuel for low level activities, once carbohydrate reserves have been exhausted. Fats provide structure at the cellular level, and are critical for proper functioning of nerves. Fats Fats are also necessary for the absorption of fat soluble vitamins (A, D, E, and K). Fats are concentrated in butter, salad dressings, and oils, but is also found in meats, and some fruits and grain products. Vitamins Substance that must be consumed through dietary means or supplementation because the body cannot produce it, or produce it in sufficient quantities to meet its requirements. Substance must be essential to at least one vital process or chemical reaction in the body. Vitamins Found in nearly all foods. Classified as either water soluble (B vitamins and vitamin C) Or fat soluble (vitamins A, D, E, K) Minerals Large group of nutrients that are composed of a variety of elements. Play a role in the structural development of tissues and the regulation of body processes. Major minerals include calcium, sodium, potassium, chloride, phosphorus, magnesium, and sulfur. Minerals Trace minerals include iron, zinc, copper, selenium, iodine, fluoride, molybdenum, and manganese. Mineral classification is based on the amount required by the body. Minerals are found in a variety of foods, but are mainly concentrated in meat, beans, and dairy groups. Water The body is composed of 55-60% water. Water is important for temperature regulation, joint lubrication, and transportation of nutrients to working tissues. Aside from water itself, water can be obtained from juices, milk, coffee, tea, and other beverages as well as watery foods. Part II Recommended Daily Allowances Recommended Daily Allowances In the first part of this presentation you learned about basic nutrients required to fuel a healthy body. Now we will take a look at how much of these nutrients our body requires. Carbohydrates As we mentioned in Part I, carbs are the body’s primary source of fuel. Firefighters are occupational athletes and must have the proper nutritional fuel sources in order to effectively do their job. Complex carbohydrates found in fruits, vegetables, whole grains are critical fuel sources for any athletes performance. Carbohydrates It is recommended the carbohydrate intake of a healthy diet be composed of 45%-60% of daily calories. This amount is the same for both males and females. Keep in mind you want the majority of your carbohydrate intake to be from complex carbohydrates, not refined sugars!!!! Fiber Fiber is a complex carbohydrate that is extremely important to a healthy diet. When eaten regularly, fiber helps to maintain digestive health, aids in satiety during meals, and slows the absorption of sugar into the blood stream. Fiber Fiber is also a critical component for removing cholesterol from the bloodstream. As LDL (low density lipoproteins) are filtered out of the blood and into bile, the bile requires an element with which to bind in order to be removed from the body. This binding element is fiber and without it the LDL will be deposited back into the bloodstream. Fiber The recommended daily allowance for fiber for men is 38 grams. The recommended daily allowance for fiber for women is 28 grams. These numbers decrease slightly for both men and women after the age of 50. Proteins Protein is necessary for cellular function, structure and repair. Protein is used as an energy source less than 5% of the time. The daily requirement of protein in a healthy diet is typically calculated as a measurement of body weight. Protein On average the recommended daily intake of protein should be in the range of 0.8-1.2 grams per kilogram of bodyweight. Intake should not exceed 2.0 grams per kilogram of bodyweight. Daily requirements can be easily met with normal food intake. Protein Excess intake of protein beyond the daily requirement can have negative side effects. These can include strain on kidney function, dehydration, increased risk of cardiovascular disease, and increased excretion of calcium from bones. And like too much of anything else, too much protein will be stored as fat. Fat Although fats have a bad reputation, they too are an important component of a healthy diet. Fat is an important source of energy, a protective mechanism, an insulator and is a necessity in various cellular functions. Fat There is no formal RDA for fat. The Acceptable Macronutrient Distribution Range (AMDR) for fat is 20%-35% of daily caloric intake. The National Cholesterol Education Program (NCEP) recommends less than or equal to 30% of total calories from fat with 10% polyunsaturated, 10% monounsaturated, and 7-10% saturated fat. Vitamins and Minerals Requirements for vitamins and minerals can differ between men and women. A well balanced diet will typically fill the daily requirements. Dietary experts recommend a daily multivitamin to ensure requirements are met. Avoid multivitamins that exceed 100% of any nutrients. Water Proper hydration is necessary for a high level of performance. Your daily requirement will fluctuate due to many factors. Your kidneys are highly sensitive to hydration levels and a decrease will quickly be noted in the color of your urine. Part III The Nutrition Label The Nutrition Label We have covered the basic dietary nutrients and how much we should include in our daily diet. Your head is starting to ache and you are still not quite sure how to apply this information to everyday life. Now we will take a look at a tool that will help you to put all this information into application! The Nutrition Label All packaged foods that we eat come complete with all of the information we need to determine whether or not this food is a good choice for a healthy diet. The next few slides will look at information provided on the nutrition label and see how that applies to our daily requirements. Serving Size Determine the serving size and how many servings there are in the food package – one package doesn’t mean one serving! Compare the serving size to how much you actually eat. You may need to adjust the remainder of your daily intake based on your typical Serving Size Continually ignoring the serving size and not controlling your portions can result in difficulty performing your job! Calories and Calories From Fat Note whether a serving is high in calories and fat. A low calorie food has 40 calories or less per serving. A low fat food has 3 grams of fat or less per serving. Total Fat Try to choose foods that do not exceed 3 grams of total fat per 100 calories. This will keep you within your healthy daily fat intake of 30%. Daily Values Percent daily values are based on a 2000 calorie per day diet. Daily value percentages tell you whether the nutrients in a serving contribute a lot or a little to your total daily diet. 5% or less is considered low. 20% or more is considered high. Nutrients To Limit Look for foods low in total fat, saturated fat, trans fat, cholesterol and sodium. 360-480mg of sodium per serving is considered an acceptable level. Cholesterol should be 60mg per serving or less. Get Enough of These!!! Look for foods high in dietary fiber, vitamin A, vitamin C, calcium and iron. A daily value of 20% or more is high. A daily value of 1019% is good. Fiber amount of 5 grams or more per serving is high. Fiber amount of 2.54.9 grams per serving is good. Part IV Resources MyPyramid.gov The Dietary Guidelines for Americans, 2005, gives science-based advice on food and physical activity choices for health. Website is interactive and allows you to individualize a well-balanced dietary program. This site allows you to establish daily caloric intake amounts which can help you determine individual nutrient amounts as described in this presentation. Department PFT’s The Prince William County Department of Fire and Rescue has over 20 certified Peer Fitness Trainers. These individuals have been trained to advise you on issues of nutrition and fitness. Contact the Health & Safety Office to find a PFT in your battalion. Part V Take Home Points Take Home Points Emphasize a diet of fruits, vegetables, whole grains, and fat-free or low-fat milk and milk products; Includes lean meats, poultry, fish, beans, eggs, and nuts. Make dietary choices low in saturated fats, trans fats, cholesterol, salt (sodium), and added sugars. Your food and physical activity choices each day affect your health—how you feel today, tomorrow, and in the future. Respiratory Protection Program – IDLH Atmospheres Purpose: – This emergency directive is being issued to address the need for all fire and rescue members to be adequately protected from respiratory hazards while operating within an Immediately Dangerous to Life and Health (IDLH) atmosphere. Respiratory Protection Program – IDLH Atmospheres – – – Authority: This emergency directive is being issued in accordance with Fire and Rescue Association Procedure 1.3.4 titled Emergency Directives. Directives may be issued without following the development and review process specified in Procedure 1.3.2, Written Direction Development, whenever it is determined that the urgency of issuing the communication constitutes an emergency. The Fire and Rescue Association may issue emergency directives at any time. The chairman may issue emergency directives under this procedure when he/she deems the circumstances warrant. Concurrence of the Association shall be granted at the next meeting of the Association for the directive to remain in effect past that date. Respiratory Protection Program – IDLH Atmospheres – Directive: In light of new studies that the Fire and Rescue Association has become aware of, it has been determined that the current respiratory protection program does not adequately protect members from Immediately Dangerous to Life and Health (IDLH) atmospheres that are present during all phases of operation at emergency incidents. Respirator Use The Fire and Rescue Association recognizes that the monitoring of atmospheres for fire and rescue personnel, where carcinogens may still be present, is not reasonable during emergency operations. Therefore, all atmospheres identified in Table 1 and any additional atmospheres identified on scene as IDLH shall require the use of SCBA throughout all phases of the operation. Respiratory Protection Program – IDLH Atmospheres Table 1 – IDLH Atmospheres IDLH Atmosphere Emergency Incident (SCBA or SAR Required) Training Scenarios (SCBA or SAR Required) Situation Description Structure Fires, HazMat/Decon, Vehicle Fires, Trash Fires, Dumpster Fires, Confined Space Entry, CO>5 ppm, O2<19.5%, O2>24%, Inside Gas Leaks, Outside Gas leaks, Salvage and Overhaul, Building Collapse, Aircraft Incidents, Rail Incidents, Marine Incidents, Anytime smoke or suspended particulates are present. *Overhauling and fire investigation can have lingering hazards even though the O2 and CO levels are acceptable. Other carcinogens may still be present, and the use of SCBA shall continue throughout the overhauling and investigation process. Confined Space, Live Fire, Vehicle Fires Respiratory Protection Program – IDLH Atmospheres Scope and/or Duration: – This directive shall remain in effect until the Respiratory Protection Program Procedure is updated and approved by the Fire and Rescue Association. Responsibilities: – Health and Safety Battalion Chief Act as the Program Administrator for the Fire and Rescue Association. As such, he/she will be responsible for the update of the Respiratory Protection Program Procedure. Respiratory Protection Program – IDLH Atmospheres Respirator Wearers Wear his/her respirator when and where required and in the manner in which he/she was trained. Report any malfunctions of the respirator to his/her supervisor immediately. Inspect, document, clean, and disinfect respirators as required. Respiratory Protection Program – IDLH Atmospheres Responsibilities (Continued) – Officers Assure that all members comply with the wearing of respiratory protection under this emergency directive.
