What harm does sodium glutamate have? Please elaborate! thank you

It is harmful to the environment and pollutes the water source.

2. Health hazards of sodium glutamate

Inhalation, ingestion or absorption through the skin are generally harmless to the body, and excessive heating will form sodium pyroglutamate, which may have a certain impact on human health.

Eating monosodium glutamate will not cause any harm to health within the normal range, but excessive consumption will cause some people to have headaches, redness, sweating, facial oppression or swelling, numbness in or around the mouth, burning sensation in the stomach, chest pain and other symptoms. After poisoning, you can take 50 mg of vitamin B6 orally every day to relieve symptoms.

Sodium glutamate will form sodium pyroglutamate at 120℃. It is generally believed that sodium pyroglutamate is not only tasteless, but also toxic and carcinogenic. However, scientists have found through experimental research that sodium pyroglutamate can improve people's memory and is not a carcinogen.

Extended data:

In China, monosodium glutamate is an essential condiment for everyone to cook, but it is rarely used in western countries. Because many studies show that long-term consumption of monosodium glutamate will have a certain impact on people's health, especially on children. There are many hazards of monosodium glutamate to human body, mainly from the following points.

1. The main component of monosodium glutamate is sodium glutamate, which can be decomposed during digestion. The latter can be converted into inhibitory neurotransmitters by enzyme catalysis in brain tissue. If you take too much, it will interfere with the natural laws of the nervous system. Therefore, some people with sensitive physique will have a series of symptoms such as dizziness, headache, lethargy, muscle spasm and even shock after eating too much monosodium glutamate, and some people will also have anxiety and confusion.

Second, when monosodium glutamate is consumed too much, too many inhibitory neurotransmitters will also inhibit the secretion of thyroid stimulating hormone in human hypothalamus, thus hindering the development of bones, especially for children. In animal experiments, it was found that young mice and chickens were most seriously injured by sodium glutamate, which would destroy the cranial and optic nerves.

Third, when the consumption of monosodium glutamate exceeds the metabolic capacity of the body, it will also lead to an increase in the content of glutamic acid in the blood, limiting the use of essential minerals such as calcium, magnesium and copper. In particular, glutamic acid can combine with zinc in blood, and the unusable zinc glutamate is excreted, resulting in zinc deficiency in human body. Zinc is an important nutrient for infants' physical and intellectual development. Therefore, infants and nursing mothers should fast or eat less monosodium glutamate.

Fourth, if you eat too much monosodium glutamate, you will often get thirsty. This is because monosodium glutamate contains sodium. Because monosodium glutamate is not salty, it is easy to eat too much and not notice it. People over the age of 60 are particularly sensitive to sodium intake, so the elderly and people suffering from diseases such as hypertension, kidney disease and edema should especially eat less monosodium glutamate.

Although monosodium glutamate is an essential condiment in our life, we still need to know that the content of monosodium glutamate in each dish should not be too much, especially when cooking for the baby, to prevent these hazards from hurting the baby.
