The safety of the pot has always been the focus of public attention: is the non stick coating toxic? Can stainless steel pot cause manganese poisoning? Does aluminum in an aluminum pot increase the risk of Alzheimer’s disease? Let’s answer the question together – < / P > < p > the commonly used material for non stick pot coating is fluorine-containing polymer, the most typical is polytetrafluoroethylene, also known as Teflon. This material is stable in the environment below 260 ℃. < / P > < p > the temperature that our cooking utensils can reach is about 200 ℃. Even if it is fried, it will not exceed 250 ℃. As long as it is not empty fired, it is difficult to reach 260 ℃. Therefore, in daily cooking, there is no need to worry about the release of harmful substances from coating decomposition. < / P > < p > the non stick pot coating itself is very thin. What happens if it is scraped off in use? Coating materials, which are acid, alkali, oil and high temperature resistant, will not be digested, absorbed and enriched by us, but directly discharged from the body through feces. So there is no need to worry. < / P > < p > there is a rumor that “foreigners do not use stainless steel, because manganese in it will lead to memory decline. Frequent use of manganese will cause damage to bones, teeth and digestive function, and even induce Parkinson’s disease.”. In fact, there is no direct relationship between manganese content and migration in stainless steel. Generally speaking, the manganese in stainless steel will not precipitate easily and dissolve into food. At present, there is no case of manganese excess and manganese poisoning caused by the use of stainless steel products. If aluminum enters the human body, it is not easy to be excreted. Over time, it will accumulate in the human body, thus affecting the health of bones and nervous system. However, it is wrong to say that aluminum can cause Alzheimer’s disease. < / P > < p > in 2008, the European Food Safety Agency (EFSA) conducted a risk assessment on aluminum in the diet. Based on the existing evidence, it was not believed that aluminum intake from food would cause Alzheimer’s disease Two evaluations were conducted in 2011, and the results showed that the current study could not conclude that aluminum can cause Alzheimer’s disease. < / P > < p > to sum up, the most commonly used pots in our daily cooking will not cause harm to human health in normal use. Of course, there is a key point, please buy in regular supermarkets in line with the national standards of the pot.
