A woman in Changsha (meaning grandma) picked up a bucket of nitrite on the roadside, thinking it was ordinary salt, so she took it home and cooked it. As a result, her three grandchildren were poisoned, developed cyanosis and other symptoms of hypoxia, and were rushed to the hospital for emergency treatment, out of danger. Compressive acidosis is very dangerous, and its toxic principle is that nitrite will combine with iron in red blood cells and become high-valent iron. So red blood cells lose their ability to carry oxygen, so the human body will lack oxygen. Through this incident, we can sum up three points to prevent nitrite poisoning, which are explained in detail below:

1, don't eat the food you picked up casually: because you can't be sure whether the food discarded on the roadside is safe, it may have expired, may have deteriorated or even been poisoned. So don't pick up something to eat just because you are greedy, just like the grandmother in the case died. Her grandchildren almost died because of greed. Especially the elderly, like this old woman, have no culture. The chemical formula of nitrite has been written on the package, and it is still used as salt. This is the loss of illiteracy. So, don't eat the food you picked up just because you are greedy and cheap.

2, eat less kimchi: because kimchi contains a lot of nitrite, so kimchi must be eaten less, because kimchi is a fermented food, bacteria will convert nitrate into nitrite during fermentation, so eating too much kimchi will lead to nitrite poisoning, so eat less kimchi.

3. It is best to blanch green leafy vegetables first: Because the leaves of green leafy vegetables are rich in a lot of nitrite, and nitrite is very soluble in water, the best way to remove nitrite from green leafy vegetables is blanching. After blanching, green leafy vegetables can be eaten more safely and safely. The above explains in detail how to prevent nitrite poisoning from three angles. As long as we pay attention to the above points, we can completely prevent nitrite poisoning.
