What happens when you eat too much monosodium glutamate?
The main component of monosodium glutamate is sodium glutamate, which can be decomposed into glutamic acid during digestion, and the latter is converted into an inhibitory neurotransmitter by enzyme catalysis in brain tissue. When monosodium glutamate is ingested too much, this inhibitory neurotransmitter will inhibit various nerve functions in the human body, resulting in a series of symptoms such as dizziness, headache, drowsiness, muscle spasm, anxiety and confusion. Some people with sensitive constitution may even feel sore bones and weak muscles. Moreover, excessive inhibitory neurotransmitters can also inhibit the secretion of thyroid stimulating hormone in human hypothalamus, hinder bone development, and have a significant impact on children.
Because monosodium glutamate contains sodium, excessive intake often leads to thirst and high blood pressure. 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.
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. Zinc deficiency can lead to mental retardation, night blindness, sexual late maturity and adult dwarfism, so babies should be carefully fed.
Excessive intake of monosodium glutamate is a vision killer, which will lead to the decline of protein and make the axis length out of control. Moreover, monosodium glutamate can also reduce taurine in human body, affect retinal development, and even some people will have temporary blurred vision after eating monosodium glutamate.
After excessive consumption of monosodium glutamate, the content of glutamic acid in human blood will increase, which will hinder the absorption of calcium and magnesium, thus causing short-term symptoms such as headache, heartbeat and nausea, and also having adverse effects on reproductive system.
Eating too much monosodium glutamate will make people dependent on it, and then eating food without monosodium glutamate will feel tasteless, which will also hinder the absorption of other nutrients.
Brief introduction of monosodium glutamate
Monosodium glutamate is a condiment, and its main component is sodium glutamate. The main function of monosodium glutamate is to increase the flavor of food. It is most used in Chinese food and can also be used in soups and sauces.
Monosodium glutamate refers to the crystallization of sodium glutamate fermented and purified from grain. From 1965, glutamic acid was produced from sugar or starch in China, and then glutamic acid was extracted by isoelectric point crystallization precipitation, ion exchange or zinc salt refining, and then sodium glutamate crystal was made by decoloration, iron removal, evaporation and crystallization.

Harm of monosodium glutamate
Monosodium glutamate is one of the most widely used flavoring agents in China. Do you know the harm of monosodium glutamate? Let me show you the harm of monosodium glutamate to human body.
The chemical composition is sodium glutamate. Monosodium glutamate is a kind of food freshener, originally extracted from seaweed, and now it is an industrial synthetic product. It has no direct nutritional value to human body, but it can increase the umami taste of food, arouse people's appetite and help improve the digestibility of food.
Some westerners have symptoms such as headache, redness, sweating, facial oppression or swelling, numbness in or around the mouth, burning sensation in the stomach and chest pain within 2 hours after eating foods rich in monosodium glutamate. This phenomenon mostly happens after Chinese food, so some westerners call it "China restaurant syndrome", but the relationship between this phenomenon and the consumption of monosodium glutamate has not been confirmed so far. Emergency treatment after poisoning: no special treatment is needed after taking excessive monosodium glutamate by mistake. People with "China restaurant syndrome" can also take vitamin B6 orally, 50mg a day.
MSG can be eaten safely, but don't overdo it. Generally, the daily consumption per person does not exceed 20 grams.
