Junk food is any unhealthy food that is high in fat, sugar and calories, but low in nutrition (营养), such as French fries, hamburgers, chips and colas. Such foods are often tasty, quick and convenient.
When teens come home from school, the first thing they often do is
unwind in front of the TV with a big bag of chips and a can of cola or another sugar-filled drink. They have unknowingly walked into the world of junk food, not realizing the danger. According to the research, teenagers who often have junk food may face health problems, such as becoming overweight and developing metabolic diseases (新陈代谢疾病). So avoiding junk food is a must for them.
The study has also found that compared with adults, teenagers today are more likely to eat junk food. Since lots of parents are busy with work and have no time to cook, teenagers are introduced to fast food at a young age, which makes it difficult for them to realize the importance of eating food for nutrition. Besides, everything is available so easily online, including ordering junk food, which makes it a lot easier for them to live a not so healthy life. Once teenagers get a taste for junk food, they are likely to keep on having it more often than home-made dishes.
▲ It all starts with parents. They should create an environment that helps protect their children’s health and also develop good eating habits. These habits will turn into a healthy lifestyle, which in turn will help them in the long run to be better adults.
