The so-called junk food, one kind refers to the food without other nutrients except calories, and the other kind refers to the food that provides more than the human body needs, resulting in redundant ingredients. In China, the consumers of junk food are very large: teenagers are the main consumers of foreign junk food such as hamburgers, potato chips and fried chicken, while middle-aged and elderly people are the main consumers of traditional junk food such as fried dough sticks and pickles. Experts pointed out that fried and grilled foods contain a lot of carcinogens, pickled and puffed foods contain a lot of harmful chemical components such as nitrite, and some foods are added with excessive artificial additives.
Junk food has done great harm to human health, but many people don't realize that its temptation is irresistible to many people. Junk food tastes good and can stimulate people's taste. In contrast, healthy food is rich in nutrition, but rarely delicious.
