We all have ideas about what kinds of foods are good to eat. We also have ideas about what kinds of foods are bad to eat. As a result, people from one culture often think the foods that people from another culture eat are nauseating(令人作呕的).When the famous boxer Muhammad Ali visited Africa, for example, one member of his group became quite sick when he saw someone pick up a butterfly and eat it. Many people would find it disgusting to eat rats, but there are forty-two different cultures whose people regard rats as appropriate food.

 Food likes and dislikes do not always seem related to nutrition. For example, broccoli is first on a list of the most nutritious common vegetables, but it is twenty-first on a list of vegetables that Americans like most to eat. Tomatoes are sixteenth on the list of most nutritious vegetables, but they are first on the list of vegetables that Americans like most to eat.

But dislike is not the only reason why some cultures will not eat a certain food. In some cultures, certain foods are taboo. Some foods are taboo in certain religions, but there are also other food taboos that are not connected to a religion. We do not usually think about why certain things are taboo in our culture. We may not even know why they are taboo. Anthropologists(人类学家) try to discover the hidden reasons for taboos.

Anthropologists believe that most food likes and dislikes are a result of the ways of life of different people. Some people live in areas where there are both large animals and many insects. It is difficult for these people to kill large animals, and it requires a lot of energy. It is easier for them to use insects for food because it is not difficult to catch insects and it does not require a lot of energy. Nomadic(游牧的) people who move around will not want to keep pigs for food. People will not eat pets such as dogs. Americans eat a lot of beef because there is plenty of land for raising cattle and the meat can be shipped cheaply for long distances by railroads.
