Potato chips have low nutritional value and contain a lot of fat and energy. Eating more will destroy appetite and easily lead to obesity. They are also the enemy of skin bodybuilding.
Eating too many potato chips is more harmful.
Danger: It causes blood pressure to rise, so that the normal flow of kidney blood cannot be maintained, leading to diabetes. The reason for this harm: potato chips have a high salt content. Eating potato chips won't stop until the taste is satisfied or the whole bag is eaten. At this time, you will unconsciously ingest a lot of salt, which will lead to an increase in blood pressure. Therefore, the normal blood flow of the kidneys cannot be maintained, leading to diabetes.
Potato chips are familiar fried snacks. The faint salty taste is accompanied by the unique earthy smell of potatoes, and the crispy taste of chewing in the mouth makes many people fondle it. Thus, couchpotatoes family was born in America. They lay on the sofa watching TV and chewing potato chips, which became a popular lifestyle in the 1960s. In Japan, there is a special "potatochipsbar", which mainly serves beer and potato chips to remind guests of their innocent and carefree childhood.
However, on the morning of June 1 65438+1October1last year, a surprising news was suddenly broadcast on Japanese TV morning news: potato chips contain acrylamide, which is extremely carcinogenic!
An unexpected discovery that the whole world did not expect.
The news comes from the research results of the Japanese Ministry of Health, Labor and Welfare (equivalent to the Ministry of Health, Labor and Welfare), which shows that high concentration of acrylamide which is considered to be carcinogenic is detected from potato chips. The Swedish government announced the opportunity to carry out this research six months ago. After a long-term follow-up survey in Sweden, it was found that if grains containing a lot of carbohydrates were cooked in cooking treatments such as barbecue and frying, acrylamide with carcinogenic effect would be formed.
This announcement immediately exploded all over the world, and the World Health Organization (WHO) convened an emergency meeting of experts to discuss the countermeasures and agreements: Britain, France, the United States and other countries, which take fried potato food as their daily snacks, took action one after another, conducted experiments and tests, and all reached positive conclusions (see the article "Healthy Black Kids Can't Be Ignored" in 2002); Japan was a little slow, but the test results also caused a strong shock. For a time, the whole world was filled with fear, and more consumers were shaken by this kind of snack food that men, women and children loved.
In the five-level classification of the risk degree of carcinogens by the International Agency for Research on Cancer (IARC), acrylamide is classified as the second level, which is quite carcinogenic. But so far it has nothing to do with food. Therefore, people's surprise and shock can be imagined when this substance is suddenly detected from the most familiar food. The food minister of Japan's National Institute of Medicine and Food Hygiene made no secret of his surprise: "It's amazing. Among the things that people have never thought about, there are chemicals that they have never thought of, and researchers all over the world have never imagined. "
Hereditary toxicity
In the five-level classification of the International Agency for Research on Cancer (IARC), 1 is the most dangerous, which belongs to the confirmed carcinogen, followed by 2A and 2B, which have high carcinogenic potential, and Grade 3 and 4 are basically harmless to human body. Among them, coal tar, asbestos, chewing tobacco and cadmium are at 1 level; Grade 2A includes acrylamide, creosote used as wood preservative, automobile exhaust, benzopyrene (contained in fried fish skin) and so on. Grade 2B includes chloroform, coffee, etc. Acrylamide in potato chips and automobile exhaust are both toxic substances that are equally harmful to human body, so it can also be said that eating potato chips is equivalent to eating automobile exhaust.
Through experiments on mice, scientists found that mice were continuously fed acrylamide at the ratio of 1 kg body weight of 2 mg, and as a result, mice developed lung cancer or breast cancer one after another. Convert this ratio into human body, assuming that the weight is 60 kg, which is equivalent to the daily intake of 120 mg acrylamide. The potato chips with the most acrylamide content were found in the test, which contained about 3.5 mg in 1 kg. In other words, eating 34 kilograms of potato chips every day will reach this carcinogenic critical point. Most of the potato chips sold in the market are about 0/00g per bag, which means that if you eat 340 bags of potato chips every day, you will get cancer in nine cases out of ten. In fact, no one will eat like this.
So, does this mean there is no danger? Although there are still differences in the judgment of researchers, there is one opinion that accounts for the majority, that is, no one dares to make the assertion of 100%. They warned: firstly, people and animals cannot be directly compared, and secondly, acrylamide has the genotoxicity of directly damaging DNA, and even a small amount of genotoxic substances cannot rule out the possibility of carcinogenesis. Therefore, "children now eat potato chips since childhood, and if they accumulate over time, the consequences will be very worrying." Potato chips contain too much aluminum, and eating too much aluminum for a long time will lead to dementia.
Aluminum is not a trace element needed by human body, but a food pollutant harmful to health. If you eat puffed food with high aluminum content for a long time, it will cause nervous system diseases, such as memory loss, visual and motor coordination failure, and even dementia in severe cases. In addition, excessive intake of aluminum will inhibit bone formation and cause osteomalacia. However, experts also reminded that occasionally ingesting a small amount of aluminum-containing food is not a big problem for the human body.
