| Food is very important in our everyday life. What do you know about food? What should we eat for dinner, fried chicken in a fast restaurant or chicken cooked in the Chinese way? It seems hard to choose. Maybe you like fast food very much, but it's not good for your body. If you have too much deep-fried food, you're more possible to get cancer. Well, it is not just potato chips that are bad for you. There are other foods that you should worry about, like coke and hot dogs. If you have too much of it, you'll get fat. If you want to be healthy, you have to learn which foods are good for you. Scientists divide foods into five different types: dairy (乳制品)? meat, grains (谷物), fruits and vegetables. No one food has them all. So we should eat less meat, oil and more fruits, vegetables, especially the deep-color vegetables. Vegetables are rich in vitamin A, vitamin C and other nutrients (营养).
