If you go to a fast food restaurant or a snack bar, you will probably see a lot of teenagers. Today, many teenagers are overweight, and some of this is because of their bad eating habits. Most teenagers love food with a lot of fat, oil, salt, and sugar. People often call this type of food “junk food”.
But bad eating habits go beyond fast food. Many teenagers find it difficult to eat healthily. Some don’t have breakfast before they go to school. During the day, some don’t have a proper meal for lunch. In a recent survey at one school, scientists found that over two-thirds of the students didn’t follow a healthy diet. Nearly half of the students didn’t like vegetables, and many of them didn’t like to eat fruits. They preferred to eat food with a lot of salt, sugar, or fat.
