What are the disadvantages of eating fast food often?

We know that seven nutrients for human survival are indispensable in our life. However, in modern fast food, what is most lacking is vitamins and minerals that are extremely important to the human body. The lack of vitamins and minerals reduces the metabolic activity of many enzymes in the body, reduces immunity, has poor disease resistance and is prone to illness. For example, the average person's daily intake of vitamin C should be 1000 mg, and the demand of adolescent boys is higher, and vitamin C mainly exists in fresh fruits and vegetables, so eating fast food often leads to a serious shortage of vitamin C and eventually leads to illness.

Experts suggest that teenagers should eat no less than 500 grams of fresh fruits and vegetables every day. Therefore, young friends, for their own health and future, try to eat less fast food.
