What are the hazards of rapeseed oil?

Ordinary rapeseed oil contains erucic acid, and animal experiments show that erucic acid is harmful to the heart. In addition, isothiocyanate, the decomposition product of glucosinolates, will interfere with the synthesis of thyroxine and lead to goiter. Nitrile can also cause liver and kidney enlargement in animals, and in severe cases, it can cause liver hemorrhage and liver necrosis.

Although it is used as edible oil, it is generally used in a small amount, and the harm caused is not necessarily great. But they are "harmful ingredients" after all, so from the health point of view, ordinary rapeseed oil is obviously not as good as other vegetable oils.

Extended data:

Many people think that "crude oil without modern industrial means" is more "healthy" and "safe". That was not the case. Earth pressed oil contains free fatty acids, pigments and volatile components, which makes the oil smoke at a relatively low temperature. Soot is not only the source of PM2.5, but also contains harmful substances such as acrolein.

Acrolein has a strong stimulating effect on eyes and respiratory tract, and it was even used as a chemical weapon during World War I. When rapeseed is "compacted", high temperature treatment will produce carcinogen benzopyrene. In addition, smoking can also produce other harmful substances.
