Take a look

Is nitrite poisonous? Will it cause cancer?

There are two main ways to consume nitrite through food: the human body:

The first is the nitrite contained in the food itself;

The second is to add to food as a food additive.

Nitrite naturally exists in many foods, such as overnight vegetables, kimchi that is marinated for a few days, etc.;

Nitrite is also allowed to be added to meat products within the legal dose within the statutory range.

Nitrite itself is not carcinogenic, but nitrite entering the body will combine with the protein disintegration in the stomach to form nitrosamines. Nitrosamine is internationally recognized carcinogen.

But! ——Adizing the toxicity of the dosage is a hooligan. Whether the food containing nitrite will cause damage to health is to see how much the nitrite content is in the food.

Can self -made kimchi (pickled vegetables) still be eaten?

Can be eaten in moderation
