Document Summary
Grilled lean meats (grilled chicken, ilet mignon, pork chop) Vegetarian meals with whole grains and legumes. Once in while, eat half of portion, share. Breaking food into tiny pieces: absorption. Moving the tiny pieces from the inside of your intestine into the blood stream: excretion. Stomach and intestines send nerve signals to hypothalamus of the brain to tell us we"re hungry. Muscle contractions from gut, signalling back to brain that stomach is empty: blood sugar levels drop. Insulin and glucagon levels in the blood change (hormones) Starts in mouth, mixes with saliva which contains the carbohydrate enzyme and moistens food so it can be swallowed. Salivary smalyse breaks u starch molecules into smaller sugar molecules (carbohydrates) Makes a bolus - parts of food you swallow - moist ball of food. Biological catalysts - facilitate chemical reactions in living things. Start out in mouth with break down of starches and fats. Bolus forces epiglottis to cover passageway to lungs.
