Many animals recognize their food because they see it.So do humans. When you see an apple or a piece of chocolate, you know thatthese are things you can eat. You can also use other senses when you chooseyour food. You may like it because it smells good or because it tastes good.You may dislike some types of food because they do not look, smell or tastevery nice. Different animals use different senses to find and choose theirfood. A few animals depend on only one of their senses, while most animals usemore than one sense.

Although there are many different types of food, someanimals spend their lives eating only one type. The giant panda eats only oneparticular type of bamboo(竹子) . Other animals eatonly one type of food even when given the choice. A kind of white butterfly(蝴蝶) will stay on the leaves of a cabbage, even thoughthere are plenty of other vegetables in the garden. However, most animals havea more varied(多样化) diet . The bear eats fruits and fish. Thefox eats small animals, birds and fruits. The diet of these animals will bedifferent depending on the season.

Humans have a very varied diet. We often eat foodbecause we like it and not because it is good for us. In countries such asFrance and Britain, people eat foods with too much sugar. This makes themoverweight, which is bad for their health. Eating too much red meat and animalproducts, such as butter, can also be bad for the health. Choosing the rightfood, therefore, has become an area of study in modern life.
