Document Summary
When glucose levels are low in the liver, you eat (you stop once they are full) once foods hit your small intestine, cholecystokinin (cck) is produced (a hormone that regulates short-term satiety) Rats w/ ckk injection ate the same amnt of food in a day as regular, but ckk rats ate more total meals. Npy is the on switch for appetite - leptin inhibits npy, therefore decreasing appetite and energy consumption. Through evolution: bitter and sour = toxic/harmful a special aqcuired taste must be learned through experience sweet, salty, savoury = nutritious. Di erences in taste sensitivity number of tasebuds (high sensitivity = more tastebuds) women > men for taste sensitivity pregnant women are especially sensitive. Chemical senses chemical senses of taste and smell depend on receptors that can interact / molecules of food particles taste and smell work together to in uence perception of avour.
