Is it harmful to fry too many times?
Fried food contains a lot of trans fatty acids, leavening agents and pigments.

Harm of trans fatty acids to health

After trans fatty acids enter the human body, they are metabolized and transformed in the body, which can interfere with the normal metabolism of essential fatty acids, such as EFA, and have adverse effects on human health: increasing the risk of cardiovascular diseases; Leading to an increased risk of diabetes; Lead to the lack of essential fatty acids; Inhibit the growth and development of babies.

The harm of leavening agent to health

The leavening agent is a substance added in food processing, which can make the product initiate and form a dense and porous structure, thus making the product fluffy, soft or crisp. In recent years, the phenomenon of aluminum content exceeding the standard in flour food has appeared continuously, which is mainly due to the excessive use of aluminum leavening agent baking powder in food processing. Excessive intake of aluminum for a long time leads to the enrichment of aluminum in the body, which affects the interaction between calcified tissue, phosphorus and vitamin D, causing damage and deformation of the skeletal system, such as rickets and osteoporosis.

Effects of excessive pigments and fixing agents on health.

Long-term excessive intake of pigments and fixing agents can lead to enrichment in the body, which can cause a series of health problems such as acute poisoning and chronic poisoning.

health problem

The hygienic problems of fried food bear the brunt, especially in China, where the hygienic standards are not standardized. There are two health problems in fried foods: First, the raw materials used for frying are unsanitary, and many fried raw materials are going to deteriorate or have deteriorated, so get some oil 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.

Toxic and carcinogenic

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.

Hurt the liver

Fried food contains a lot of oil and fatty acids. Long-term consumption will increase cholesterol levels. If you don't pay attention to it, it will damage the liver and then suffer from fatty liver. If fatty liver is not treated in time, it may be complicated with chronic diseases such as diabetes, and may also aggravate the original lesions in the body. In severe cases, it will lead to abnormal metabolic function, so you should try to eat less or not to eat fried food.

Excessive aluminum content

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

Harmful to human body, aluminum is an amphoteric element, that is to say, aluminum can react with acid and alkali, and the compounds formed after the reaction can be easily absorbed by the intestine and enter the brain, which will 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.

Low nutrition

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.

Lead 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. It smells good and tastes good.

Can be put into the 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.
