Is MSG bad for the brain? Is MSG harmful to the human body?

There are foods that eat instant noodles and have a lot of MSG for a long time, which will cause your hair to be damaged, and your hair is prone to gray hair

It's really not good to eat too much monosodium glutamate, my family has not used monosodium glutamate for more than a year, including chicken essence, my experience is: as long as the raw materials are fresh, the dishes made are not put in monosodium glutamate, chicken essence are the same fresh, really, don't believe it, you try :) The following is a professional explanation of Xinhuanet.

Many people are accustomed to putting MSG in stir-frying, but according to a recent survey in Taiwan, about 30% of people have drowsiness and anxiety due to excessive intake of MSG.

The main component of monosodium glutamate is monosodium glutamate, which can be broken down during digestion, which is catalyzed by enzymes in brain tissue and can be converted into an inhibitory neurotransmitter. When excessive intake of MSG, this inhibitory neurotransmitter will inhibit various nerve functions in the human body, resulting in a series of symptoms such as dizziness, headache, drowsiness, and muscle spasms; Some people will also be anxious and flustered; Some people with more sensitive constitutions may even feel sore bones and weak muscles. In addition, too much inhibitory neurotransmitter can also inhibit the secretion of thyroid-releasing hormone by the body's hypothalamus, hindering bone development, especially in children.

If you eat too much MSG, you often feel thirsty, because MSG contains sodium, and excessive intake can lead to high blood pressure. People over the age of 60 are particularly sensitive to sodium intake, so the elderly and people with diseases such as high blood pressure, kidney disease, and edema should especially eat less MSG.

When too much monosodium glutamate is consumed, which exceeds the body's metabolic capacity, it will also lead to an increase in the content of glutamate in the blood, limiting the body's utilization of essential minerals such as calcium, magnesium, and copper. In particular, glutamate can combine with zinc in the blood, resulting in zinc glutamate that cannot be used and excreted from the body, resulting in zinc deficiency in the body. Zinc is an important nutrient for the physical and mental development of infants and young children.

Therefore, infants and breastfeeding mothers should fast or reduce MSG. In addition, Japanese researchers believe that long-term excessive consumption of MSG may lead to thinning of the retina, vision loss, and even blindness.

So, how much MSG per meal is appropriate? Researchers recommend that each dish should not exceed milligrams. The severity of MSG will vary depending on the individual's physique. Therefore, everyone should also pay attention to health when enjoying delicious food.

Under normal circumstances, the consumption of monosodium glutamate is not harmful to the human body. However, excessive consumption of MSG can be harmful to the body. Consuming too much monosodium glutamate will lead to an increase in the amount of monosodium glutamate in the human blood, which can be catalyzed by enzymes into an inhibitory neurotransmitter in brain tissue, causing a series of symptoms such as dizziness, headache, drowsiness, and muscle cramps.

Some sensitive people may experience symptoms such as weight loss, bone pain, muscle weakness, etc. This effect is especially pronounced in children, who often feel thirsty and stunt bone development.
