What is the harm of excessive consumption of monosodium glutamate?
1. The main component of monosodium glutamate is sodium glutamate, which can be decomposed in the process of 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. \x0d\ Second, when monosodium glutamate is ingested too much, too many inhibitory neurotransmitters will also inhibit the secretion of thyrotropin 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. \x0d\ Thirdly, 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. \x0d\ 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.
