Humans eat because of the sensation of hunger, and they eat certain foods, partially due to learned responses and partially due to the anatomy and physiology of their digestive system. Moreover, the digestive tract has certain controls which affect digestion and absorption. Also, some foods influence digestion and absorption. Like any system, however, there are functional problems which can occur.
