Document Summary
Hunger - the primarily physiological (internal) drive to find and eat food, mostly regulated by internal cues to eating. Appetite - the primarily psychological (external) influences that encourage us to find and eat food, often in the absence of obvious hunger. Satiety - state in which there is no longer a desire to eat. Nutrients - chemical substances in food that contribute to health, many of which are essential parts of a diet. Nutrients nourish us by providing calories to fulfil energy needs, materials for building body parts, and factors to regulate necessary chemical processes in the body. Essential nutrients - in nutritional terms, a substance that, when left out of a diet, leads to signs of poor health. The body either cannot produce this nutrient, or cannot produce enough of it to meet its needs. If added back to a diet before permanent damage occurs, the affected aspects of health are restored.
