单项选择题

(一) Today our knowledge of food and what it does for our bodies are far more advanced than that of the old times. Now we know about vitamins and how each kind of vitamin helps in the growth of a particular, the food that we eat will take care of our body and so there is no need to take any kinds of vitamins unless our doctor tells us that our bodies are short of something which can be supplied by them. Generally speaking, everything we eat does some good to our body. But if we eat too much of one kind of food and pay too little attention to others, we may have too much of one kind and not enough of others. Then we may be in trouble. We are often told that we must eat some meat at each meal in order to get the necessary proteins. That is only partly true, for proteins are not found only in meat. We can also get them from some vegetables. The best advice about what to eat is that we should eat all kinds of food but never too much of any.
