Scientists have learned a lot about the kinds of food people need. They said that there are several kinds of food that people should eat every day.
★Wheat, corn or rice ★Green and yellow vegetables
★Meat, fish and eggs ★Fruit like apples, pears and so on
★Milk and butter ★All kinds of nuts
People in different countries and different places of the world eat different kinds of things. Food is cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day. In other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether food is eaten raw or cooked, cool or hot. It doesn’t matter if a person has dinner at four o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
