Description of the problem:

There are many salty things cooked in the breakfast shop in my school. I often eat it. I feel chest pain and throat discomfort. Could it be industrial salt?

Analysis:

After eating industrial salt, you will feel dizzy, vomiting, diarrhea and general weakness, but you should not. These symptoms may be psychological effects.

Experts say that industrial salt is mainly used in alkali making, boiler softening water, dyes, soaps, washing powder, feed processing and other fields, but it is harmful when it flows into the edible field. Because it contains nitrite and other ingredients, people will suffer from chronic poisoning after eating it. Generally speaking, as long as people ingest .2 to .5 grams of nitrite, it will cause poisoning; Ingestion of 3 grams of nitrite can cause death. At the same time, industrial salt does not contain iodine, and serious iodine deficiency in human body will lead to diseases. The relevant person in charge of the Provincial Salt Bureau said that scientific research shows that if people are short of iodine, they will suffer from 1% to 2% intellectual loss, and in severe cases, their children will be skinny or demented.
