What Kinds of Food Do People Need? Scientists have learned a great deal about the kinds of food people need. They say that there are several kinds of food that people should eat every day. What are these categories of food? They are 1) green vegetables of all kinds, such as string beans, peas, lettuces, and cabbages; 2) other vegetables, including beets, onions, carrots, tomatoes and so on; 3) fruits, such as apples, peaches and bananas; 4) meat of all kinds, fish, and eggs; 5) milk and food made from milk, such as buffer, cheese and ice cream; and 6) bread or cereal. Rice is also in this class of food. People in different countries and different areas of the world eat different kinds of things. They also cook their food in different ways and have theirdinner at different times. Scientists say that none of these differences are really important. It doesn?t matter whether food is eaten raw or cooked, canned or frozen. It doesn?t matter if a person eats dinner at four o?clock in the afternoon or at eleven o?clock at night. The important thing, they say, is that every day a person should eat something from each of these kinds of food. There are two problems, then, in feeding the every-increasing number of people on Earth. The first is to find some way to feed the world population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.人们需要什么样的食物？科学家们已经学会了大量的食物种类的人需要。他们说，有几个种类的食物，人们应该吃的每一天。这些食物的种类是什么？他们是1）绿色蔬菜的各种，如字符串豆类，豌豆，莴苣，卷心菜；2）其他蔬菜，包括甜菜，洋葱，胡萝卜，西红柿，等；3）水果，如苹果，桃子和香蕉；4）肉的各种，鱼，蛋；5）牛奶和牛奶的食品，如缓冲，奶酪和冰淇淋；6）面包或谷类食品。大米也在这一类的食品。不同国家和地区的人吃不同的东西。他们还煮食物以不同的方式在不同的时间theirdinner。科学家们说，这些差异是非常重要的。这并?不管食物是生吃或熟吃，罐头装的或冰冻的。如果一个人在四?时钟在下午或在十一点?时钟在晚上吃晚饭也?要紧。他们说，重要的是，每一天，每个人都应该吃点东西。有2个问题，然后，在喂养的每一个越来越多的人在地球上。首先是要找到一些方法来养活世界人口，这样就没有人饿了。其次是要确保人们在世界各地都有合适的食物，使他们变得强壮和健康。Americans??Favorite?Food?—the?Hamburger?Americans?consume?some?38?billion?hamburgers?a?year.?And?they?account?for?nearly?60?percen
