Industrial salt contains a large amount of sodium nitrite. Nitrite has a destructive effect. After it enters the body, it can turn the oxygen-carrying low iron hemoglobin in the body into methemoglobin. When methemoglobin encounters oxygen, it is firmly combined and difficult to separate. In this way, the whole body tissues of the human body will be deprived of oxygen, especially the brain, which has the most serious impact on the human body. Therefore, industrial salt is not edible.

After eating industrial salt containing a large amount of sodium nitrite, symptoms and signs include headache, dizziness, fatigue, chest tightness, shortness of breath, palpitations, nausea, vomiting, abdominal pain, diarrhea, lips, nails, and skin and mucous membranes all over the body. Cyanosis, etc., even convulsions, coma, and in severe cases can be life-threatening.
