What are junk foods?

There are a lot of junk foods in our lives nowadays, and there are many kinds.

The most important harm of eating junk food is that it affects the body's normal absorption of nutrients and causes malnutrition. This is because most junk foods have very low nutritional value, and the content of vitamins and minerals is pitifully small. Moreover, they will occupy the human stomach and affect the body's intake of other foods. After a long time, it will lead to malnutrition in the human body and will also affect human health.

2. Cause obesity

It will also cause obesity, because although junk food has low nutritional content, it is high-calorie food. After people eat it, a large amount of calories will accumulate in the body. After a long time, it will cause fat to accumulate in the body, which can easily lead to a significant increase in weight, and in severe cases, it will cause obesity.

3. Increased incidence of chronic diseases

People who often eat these junk foods in daily life will also cause a high incidence of some chronic diseases, because these junk foods contain a lot of sugar or refined starch. People's blood sugar index will rise rapidly after eating them, which will cause a high incidence of diabetes. In addition, people who often eat fried junk foods will also cause abnormal blood lipids, easily develop coronary heart disease and arteriosclerosis, and in severe cases, it will also cause a decline in human heart function.
