Can nitrite itself cause cancer and why is nitrite prone to cancer

Although nitrite itself is not carcinogenic >, nitrite reacts with protein decomposition products under acidic conditions, which is easy to produce nitrosamine carcinogens, and the pH of the stomach happens to be suitable for the formation of nitrosamines.

In the case of insufficient stomach acid, the multiplication of bacteria in the stomach reduces the originally non-toxic nitrate in food to nitrite, which increases the risk of stomach cancer.

Therefore, nitrite has a certain effect on the human body, and excessive intake may increase the risk of stomach cancer, but "increased risk" does not mean "necessarily carcinogenic".

Yes, it is carcinogenic in itself.

Wish. Thank you.

Nitrite itself is not very harmful, but after it is inhaled into the human body, nitrosamines will be generated through action, nitrosamines are strong carcinogens, so whether it is industrial preservative or food preservative, foreign countries have strict control.

If you have any questions, add q to communicate.

Anti-rust think tank, for you to answer.

This is already common sense, it will!

Yes, for sure, it's carcinogenic.

Nitrite is widely found in food ingredients, almost no meat, and especially more in vegetables, and "the nitrate content in vegetables is ranked from high to low, in order: petioles, leaves, stems, roots, flowers, tubers, bulbs, fruits, and seeds". This is due to the widespread existence of nitrogen in nature, and the nitrogen content in plant fertilizers is also extremely high, plants absorb nitrogen in the natural environment and synthesize amino acids through complex biochemical reactions, in this process, nitrate is essential, and the reductase contained in the plant will convert a part of the rapidly buried nitrate into nitrite.

Therefore, nitrite is not produced by humans during the post-processing and preservation of food, but is a substance that is already present in food.

The claim that "nitrite causes cancer" is not comprehensive. When experts talk about nitrite, they talk more about the toxicity of nitrite. The toxicity of nitrite is mainly due to its ability to oxidize hemoglobin to methemoglobin, which causes hypoxia and leads to cyanosis.

It is generally thought that adults who ingest more than 200 mg of nitrite at a time may have a toxic reaction. In cases where an infant ingests too much nitrate-containing water or food may cause "blue baby disease", it is also thought that nitrate conversion to nitrite is also caused. The reason why nitrite is carcinogenic is that ingested protein will break down amines, and nitrite will combine with these amines to form nitrate amine, which is a carcinogenic substance.
