Eating is usually a group activity. Different racial, national, and religious groups develop their own food preferences. These preferences are passed on to the children. When the children grow up, they usually feel most comfortable with the kinds of food they had in their own homes. Food choices have little to do with hunger. You may eat what your friends eat. You may use food to identify yourself as a member of a group. Some people order the most expensive dishes on a menu, just to show that they can afford them. Expensive food, like an expensive car, can help to make some people feel important. Low-cost menu choices may be just as nourishing. Your feelings and your appetite work together. You may overeat when you are worried or lonely. People sometimes eat when they feel insecure or think that no one likes them,or they may turn to food to calm themselves. Emotions may also cause under-eating. People who feel down may eat very little Many people worry so much about being overweight that they don’t eat enough.
