Scientists say there are seven kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2) citrus(柑橘类)fruits and tomatoes; (3) potatoes and other fruits and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made of milk, like cheese and ice-cream; (6) bread or cereal(谷类), rice is also in this kind of foods; (7) butter, or something like butter, with fat(脂肪)。
People in different countries in the world eat different kinds of things. They also eat different kinds in a day. In some place people eat once or twice a day; in other countries, people eat three or four times a day. Scientists say that these differences are not important. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is that every day a person must eat something from each of the seven kinds of food. The most important thing is that we must find some ways to help the hungry people and make the people have right kinds of food, make them strong and healthy
