Eating fried food often is easy to cause cancer, because fried food is easy to produce nitrite after high temperature treatment, and fried food is not easy to digest and greasy, which is easy to cause stomach problems. Fried food is high in calories, oil and oxidant, which can easily lead to obesity if eaten frequently. It is a dangerous food, which can lead to hyperlipidemia and coronary heart disease. No matter the nutrition of vitamins A and E in oil is destroyed at high temperature, the nutritional value of oil is greatly reduced, and a large number of carcinogens are produced only during frying. Studies have shown that the incidence of some cancers in people who eat fried foods frequently is much higher than that in people who don't eat fried foods or seldom eat fried foods.

First of all, fried food is not easy to digest, and it is easy to get stomach trouble if you eat too much. The child's gastrointestinal function has not been fully developed, and high-temperature food entering the stomach will damage the gastric mucosa and get gastritis. Oil will produce a substance called "acrylic acid" at high temperature, which is difficult to digest. Children who eat too much fried food will feel chest tightness, even nausea, vomiting or indigestion. Individual children will not be able to eat for several consecutive meals after eating fried food.

Secondly, the appearance of food is often covered with starch before frying. At high temperature, vitamin B 1 in flour is completely destroyed, so vitamin B 1 deficiency will occur after eating fried food for a long time.

Third, oil that is used repeatedly at high temperature will produce a carcinogen. Many families are used to storing fried food oil and using it repeatedly, which is very harmful to their health.

Fourth, it is easy to lead to childhood obesity. According to the regulations, the heat energy provided by fat in a day's diet should account for 25% ~ 30% of the total heat energy in the whole day. However, children who often eat fried food, the daily calories provided by fat obviously exceed the above indicators, so it is easy to become obese.
