The hygienic problems of fried food bear the brunt, especially in China, where the hygienic standards are not standardized. There are two aspects to the hygiene problem of fried food: First, the raw materials they use for frying are unsanitary, and many fried raw materials are going bad or have gone bad, so do something to decorate the facade. Second, the oil used is unsanitary, and many unscrupulous vendors often fry food in ditches. Even if some vendors use qualified cooking oil, in order to save costs, they often heat the oil at high temperature repeatedly, which makes the oil fried black, which undoubtedly increases the content of carcinogens and harmful substances. In addition, because fried food is cooked at high temperature in a very short time, it is often fried brown (mushy) outside and not cooked inside, which not only can not effectively kill pathogenic microorganisms in food, but also easily cause diseases such as intestinal parasites.

2, leading to obesity

Fried food, whether it is foreign fast food or our old traditional fried dough sticks and oil cakes in China, are all high-fat foods. Smell incense in your nose, eat incense in your mouth, and put it in your stomach. High fat is not conducive to digestion, not only affects your stomach, but also leads to obesity. In this slim society, I would rather starve to death than live fat. Obesity will also bring more health problems. Instead of spending money to lose weight every day, it is better to control your diet. What? Are you losing weight now? I *, that you dare to eat fried, die?

3, produce toxic and harmful substances

Repeated high-temperature heating of oil will produce toxic and harmful substances. Because after repeated high-temperature heating of oil, the polymers produced by high-temperature heating of unsaturated fatty acids-dimers and trimers-are very toxic. Most fried and baked foods, especially French fries, contain a high concentration of acrylamide, commonly known as propyl poison, which is a carcinogen. Of course, it is not the wishes of heroes to die young. So what? If you don't eat, it's over.

4. The nutrients are severely damaged.

Food is fried at high temperature, and various nutrients in it are seriously destroyed. High temperature makes protein fried and deteriorated, reducing its nutritional value. High temperature will also destroy fat-soluble vitamins in food, such as vitamin A, carotene and vitamin E, and hinder the absorption and utilization of them by human body. In other words, can fried food be healthy if it should not be and should not be?

5, aluminum content seriously exceeds the standard.

Many people often eat fried dough sticks and cakes for breakfast. However, due to the addition of alum, the aluminum content seriously exceeded the standard. Excessive intake of aluminum will be harmful to human body. Aluminum is an amphoteric element, which means that aluminum can react with acids and bases. The compounds formed after the reaction are easily absorbed by the intestine and can enter the brain, which may affect children's intellectual development and may lead to Alzheimer's disease. In addition, after the dough is treated with alum, the alkalinity is very high, which makes the vitamin B 1 lose.

6. Induced diseases

Fried food contains a lot of fat and is not easy to digest. Eating fried food often can cause indigestion, chest tightness, even nausea, vomiting, diarrhea, loss of appetite and so on. People who often eat fried food are prone to get angry and constipation due to lack of vitamins and water.
