What harm does sodium metabisulfite do to the human body

Sodium metabisulfite is a kind of food additive, which can cause harm to human respiratory tract and digestive tract. Specifically, the harm of sodium metabisulfite can be divided into the following points:

First, digestive tract damage: when sodium metabisulfite is dissolved in water, it will produce sulfite, and if it is taken by mistake, it will cause corrosive damage to the intestine. In addition, the misuse of sodium metabisulfite can also lead to liver and kidney function impairment, severe cases may even occur acute poisoning, threatening life safety.

Second, respiratory tract damage: sodium metabisulfite decomposition in the air will produce sulfur dioxide, which is a pungent odor of gas. Inhaling sulphur dioxide can damage the mucous membranes of the human respiratory tract, causing respiratory problems such as irritating cough or asthma.

To sum up, sodium metabisulfite as a food additive, although it has certain applications in the food processing industry, it is absolutely not edible. Ingestion can harm the respiratory tract and digestive tract of the human body, causing respiratory problems, corrosive damage, and liver and kidney function impairment. Therefore, we should pay special attention to avoid ingesting sodium pyrosulfite in daily life.
