the liver is easily damaged.

There are a lot of aflatoxins in edible oil. If the edible oil is heated repeatedly, this toxin will be more easily absorbed by the human body. If absorbed in large quantities, there will be acute liver poisoning and death, and small intake will lead to chronic liver cell poisoning, which will cause liver cells to slowly die, and may cause liver cancer after severe cases. In this case, this toxin is comparable to arsenic, even more toxic than it.

easy to induce cancer.

These unqualified edible oils also contain benzopyrene and acid value. Benzopyrene is a toxic substance with strong carcinogenicity, which easily leads to the stimulation of human gastrointestinal mucosa. If this happens for a long time, it will easily induce gastric cancer and intestinal cancer. Benzopyrene is emitted by oil fume after high temperature heating, and the human body sucks it into the lungs, which destroys the lung structure and easily induces lung cancer. The acid value is easy to cause a certain chemical substance to exceed the standard. After the human body uses it, it is prone to intestinal discomfort, such as diarrhea and stomachache. The risk of suffering from gastrointestinal diseases is particularly high and it is easy to damage the liver.

it is easy to cause the decline of human immunity.

Since these unqualified edible oils contain so many harmful substances, after being absorbed by the human body, various organs and system barriers will be easily destroyed or the defense function will be reduced. Under such circumstances, there are so many bacteria, viruses, harmful toxins, etc. in the outside world that it is easy to attack the human body and make it sick, that is to say, the immune function of the human body will be greatly reduced and there is no way to contribute to its own protection. In a word, these cooking oils are not qualified, which is harmful to human body and tells us not to eat these unhealthy foods as much as possible.
