　　You've just finished a heavy meal and are full up. Suddenly, your host announces proudly that he will be serving his "house specialty" dessert, bananas flambe and that he has spent thebetter part of the afternoon preparing it. Even though you are foil and don't even like bananas,you accept a serving of his dessert and eat it all.

　　Clearly, biological factors do not fully explain our eating behavior. Social factors, based on societal rules and on what we have learned about appropriate eating behavior, also play an important role. Take, for example, the simple fact that people customarily eat breakfast, lunch and dinner at approximately the same times every day. Because we tend to eat on schedule every day, we feel hungry as the usual hour approaches.

　　Similarly, we put roughly the same amount of food on our plate every day, even though the amount of exercise we may have had, and consequently our need for energy supply, varies from day to day. We also tend to prefer particular food over others. Rats and dogs may be a delicacy in certain Asian cultures, but few people in Western cultures find them appealing despite theirpotentially high nutritional value. In sum, cultural influences and our individual habits play important roles in determining when, what, and how much we eat.

　　Other social factors relate to our eating behavior as well. Some of us head toward the refrigerator after a difficult day, seeking comfort in a scoop of Heath Bar Crunch ice cream. Perhaps when we were children, our parents gave us food when we were upset. Eventually, we may have learned to associate food with comfort. Similarly, we may learn that eating, which focuses our attention on immediate pleasures, provides an escape from unpleasant thoughts. Consequently,we may eat when we feel upset and anxious.

21. What causes you to accept the host's dessert offer at the end of the meal?
