Appetite- psychological influences that encourage us to find and eat food, often in the absence of obvious hunger. Satiety- state for no longer a desire to eat (hunger scale: eat at 3-4, stop at 5-6) Nutrition- science that links food to health and disease. Nutrients- chemical substances in food that contribute to health to health. Provide building blocks for growth and maintenance. Essential nutrients- substances obtained from food that are vital for growth and maintenance of a healthy body throughout life. At least one specific biological function of the nutrient must be identified in the body. Omission of the nutrient from the diet must lead to a decline in certain biological functions. Replacing the omitted nutrient in the diet before permanent damage occurs will restore those normal biological functions. Cancer- condition characterized by uncontrolled growth of abnormal cells.
