What are the disadvantages of eating fried dough sticks?

The taboo of fried dough sticks is 1. It is not advisable to eat fried dough sticks often. As we all know, deep-fried dough sticks are high-temperature fried foods. When the oil temperature reaches 190℃ and the oil is used repeatedly, the aging color of the oil will become darker, the viscosity will increase and the smell will increase. Various nutrients contained in oils and fats, such as essential fatty acids and vitamins, are basically or completely destroyed by oxidation, and unsaturated fatty acids polymerize to form dimers and vitamins. Animal experiments show that after feeding rats with high-temperature heating oil for several months, stomach damage and papilloma, as well as liver cancer and lung adenoma appear. Therefore, it is considered that high-temperature oil may cause cancer and people should attach great importance to it. Many scholars believe that various polymers, especially dimers, produced by repeated high-temperature heating of unsaturated fatty acids are very toxic. A large number of animal experiments show that these polymers can affect the normal development of animals, reduce reproductive function, make liver function abnormal and hepatomegaly. In addition, the addition of alkali and alum in the dough of fritters has a certain destructive effect on the nutritional components of flour. Therefore, in order to prevent the aging of oil, it is necessary to change new oil frequently when frying fried dough sticks, so as to minimize or reduce the generation of harmful substances. In addition, fried dough sticks contain aluminum, which is a low toxic and unnecessary trace element and an important factor causing various brain diseases. It is an inhibitor of many enzymes, and its toxicity can affect protein synthesis and neural mediators. Aluminum can inhibit the activity of enzymes in the brain, thus worsening the mental state. Therefore, long-term excessive intake of aluminum can lead to Alzheimer's disease. Therefore, fried dough sticks should not be eaten as breakfast often, just to adjust the taste, and it doesn't hurt to eat them once in a while. 2, convalescent patients and the elderly should not eat all kinds of nutrients contained in the strips, fried dough sticks are indispensable substances to maintain life, regulate physiological functions and carry out metabolism. For convalescent patients, it can also repair and restore damaged tissues and organs and increase the body's resistance. "synopsis of the golden chamber" wrote: "the flavor contained is suitable for illness and harmful to the body. If it is suitable, it will be suitable for the body and the victim will get sick. " It shows that diet is closely related to health and the occurrence and recovery of diseases. Fried dough sticks belong to high-temperature fried food, with high melting point and long retention time in the stomach, which is not easy to digest and affects sleep. Most nutrients in fried dough sticks are destroyed, and high-temperature oil also contains certain toxic substances, which will affect the recovery and health of the body. Old people should not eat greasy and indigestible food because of the decline of physiological function, stomach function and poor intestinal absorption ability. The normal food intake of the elderly is reduced, and their metabolism is disordered, which easily leads to some vitamin deficiencies, such as VB 1, VB2, etc. The high-temperature fried dough sticks just destroy these two vitamins the most. Coupled with the harmful substances contained in oil pollution, it is easy to make the incidence of senile diseases such as coronary heart disease and arteriosclerosis remain high, which affects the health of the elderly and is not conducive to enhancing their physical fitness and prolonging their lives. 3. Pregnant women and children should not eat. Pregnant women and children are in the stage of increasing nutrition and strengthening physique, and all kinds of nutrients are needed. It is very important for pregnant women to choose a proper diet and avoid irritating and indigestible foods, while fried dough sticks are indigestible foods and do not meet the dietary requirements of pregnant women. The essential fatty acids, fat-soluble vitamins A, D and E contained in oil after high temperature are destroyed by oxidation, which reduces the nutritional value of oil. Edible oil strips are difficult to supplement various nutrients and can also cause anorexia, so pregnant women should not eat fried dough sticks. Children should not eat high-temperature fried food. In addition to the above shortcomings, fatty acids in high-temperature oil combine with calcium in the intestine to form soap calcium, which is excluded from the intestine, affecting children's absorption of calcium, easily causing children's partial eclipse and affecting their normal development. To sum up, fried dough sticks are a traditional food, but if they are eaten frequently, they are harmful to human health.
