Vocabulary Words Nutrients – substances in food that your body needs to function properly to grow, to repair itself, and to supply you with energy. Hunger – natural drive that protects you from starvation. Appetite – a desire, rather than a need, to eat. Nutrition – the process by which the body takes in and uses food.

Why Do You Eat? Foods are body’s source of nutrients. Nutrients in food affect how you look, feel, act, grow, and function (all sides of the health triangle). Eating habits stem from both a physical need for food and a psychological desire for food. Learning to recognize the difference can help you make more healthful food choices.

Your Body’s Need for Food Most basic reason for eating is physical. Food, air, and water are life’s basic needs. Your body tells you through hunger when it needs food. When the stomach is empty, its walls contract, stimulating nerve endings. These nerve endings signal your brain that you need food. Once you consume food, the stomach walls are stretched and the nerve endings are no longer stimulated.

Your Mind’s Desire for Food Making room for dessert, eating in response to the aroma of a certain food(s), and eating to be sociable are all in response to appetite. Appetite is shaped/learned through: Your environment Your emotions

Environment Culture – picnic, county fairs, movies, baseball games, holidays? Ethnic background and religion influence food choices in many homes. Family & Friends – As a child, you learn eating habits from family that influence you throughout life. As you age, friends begin to influence your food choices (try new foods). Advertising –While many ads are responsible, others are misleading. (low fat/high in calories). $Millions spent annually on power persuasion techniques (status, sex appeal, weight loss, appearance). To make informed food choices, YOU need to know about food and health. What have you bought lately that was advertisement driven? Time & Money –cost and convenience affect food shopping decisions.

Managing Your Eating Habits Avoid being influenced by others in making your food choices. Make choices with your health in mind – not just you appetite. Pay attention to quantity. Pay attention to portion sizes. When you feel full put down the fork and spoon! It takes about 20 minutes for your stomach to completely signal your body that it is satisfied. Make something other than food the focus of everyday social interactions. Instead of always getting together with friends over food, try meeting at a park, community facility, or someone's home.
