1, acrylamide
Acrylamide is mainly formed in the cooking process of plant foods with high carbohydrate and low protein (1above 20℃). Starch-rich foods such as potatoes will produce excessive acrylamide when cooked and fried at high temperature. Acrylamide has moderate toxicity, subacute poisoning can occur when exposed to a large amount, and chronic poisoning can occur when exposed to low concentration for a long time, which has mutagenic effect and can cause gene mutation and chromosome abnormality in mammalian somatic cells and germ cells. However, there is not enough epidemiological evidence to show that there is a significant correlation between the intake of acrylamide in food and the occurrence of some human tumors. The International Agency for Research on Cancer evaluated its carcinogenicity and classified acrylamide as a class 2 carcinogen, which may cause cancer to human beings.
2. Reduce memory
French fries sold in fast food restaurants are very harmful to human health. According to the latest research, some ingredients contained in French fries may seriously affect the memory of the brain. A study abroad also found that if you don't develop good eating habits in adolescence, the probability of developing Alzheimer's disease in old age will be much higher than others. Therefore, in our daily life, we should develop good eating habits.
The reason why fried foods affect our brain's memory is because these foods contain a lot of trans fatty acids, which can resist a kind of cholesterol that can promote human memory.
3. Obesity
It can be said that all kinds of food in fast food restaurants are the reasons for the increase of obesity rate of modern people, whether it is French fries, fried chicken legs or coke, they are closely related to the obesity problem of modern people. This is because this kind of food contains a lot of trans fatty acids, and this kind of fat is very difficult to be digested by human body. In this case, the correct fat in these foods will accumulate in the abdomen, which will lead to obesity, which is also the reason why there is fat on the abdomen.
Therefore, experts especially remind people who like to eat snacks such as French fries in daily life to be vigilant. Trans fatty acids in fried foods can lead to obvious fat accumulation. In order to lose weight, such foods must be eliminated.
4, coronary heart disease
Some experts also pointed out that the occurrence of various cardiovascular and cerebrovascular diseases is also closely related to foods such as French fries. It can be said that French fries are the chief culprit in inducing coronary heart disease. According to a recent study, trans fatty acids in various fried foods can reduce cholesterol content, and if these foods are eaten for a long time, they can effectively prevent heart disease and other cardiovascular diseases. In this case, the incidence of heart disease and other vascular diseases will increase, which will seriously affect human health.
Moreover, excessive consumption of such foods in daily life may also lead to the formation of knife thrombosis. This is because trans fatty acids can increase the viscosity and cohesion of human blood, especially for some people with fragile blood vessel walls.
5. The fetus is unhealthy
In particular, some pregnant women and lactating women should pay more attention to eating less fried foods such as French fries in their daily lives. If such women eat too much food containing trans fatty acids, it will seriously affect the health and growth of fetuses and newborns. Studies have found that fetuses or babies can passively ingest trans fatty acids through placenta or milk, thus affecting growth and development.
These are the hazards of French fries and other foods to human body. For our health, we should try to stay away from these foods. In addition, if male friends eat too much of this kind of food, it may affect their normal sexual function.
Second, how to eat French fries healthily
1, don't fry the French fries for too long.
Sugar and amino acids in French fries will undergo chemical changes during frying, resulting in acrylamide, which is a potential carcinogen. With the extension of frying time, dehydration and dark color of French fries, the acrylamide content will also increase obviously.
Although the amount of acrylamide consumed by consumers at present is not enough to affect their health, the time of French fries should be controlled. When making French fries, lemon color and golden color are appropriate to avoid being fried into yellow brown.
2, French fries should not be eaten more
French fries are rich in starch, and the surface is crisp after frying, but the oil adsorption is more, so they are typical high-energy foods. The fat content of large packaged French fries in fast food restaurants is about 25g, which is almost the upper limit of recommended daily intake of vegetable oil for adults in the Dietary Guidelines for China Residents. Consumers should pay attention to dietary balance, properly control energy intake and maintain a balanced diet.
3. Pay attention to the hygiene of frying oil and raw materials.
At present, there are semi-finished French fries on the market, and consumers should buy them from regular channels. It is difficult to keep the taste of French fries after storage, so it is recommended to make one finished product at a time. If the residual oil of French fries is more and the color is darker, it is recommended to discard them directly. If the remaining oil has no obvious discoloration and viscosity, it can be used to make cold dishes, but don't pour it back into the oil pan.
