Explain the possible health consequences of diets rich in fats. Energy content (kilojoules) per 100g of protein, carbohydrate, fat Food molecule Energy Content(kj) per 100 grams Fat Proteins Carbohydrates Below calculate the percent difference between the energy content of a 100 grams of fats and the energy conent difference in 100 grams of carbohydrates. Ethnic Groups & Energy Sources. Below identify four different ethnic groups & State their energy sources. Ethnic Group Energy Source 1. 2. 3. 4. Appetite Control: Appetite control is regulated by a combination of feedback loops from the central nervous system, the digestive system and the endocrine system. Show your understanding of the appetite control by making a flow chart of these feedback loops. In your flow chart be sure to include the following hormones, endocrine glands, tissues, sensations: Empty—not eaten for awhile Recently ingested food PYY3-36 Hormone released Pancreas Brain (hypothalamus gland) Inhibitory Neurons (suppresses appetite) Stimulatory Neurons (increases appetite) Ghrelin hormone released Insulin Carbohydrate uptake in liver cells Leptin hormone is released from adipose tissue Feel full (satiated) Feel empty (hungry Tuna Can Cookies Chips
