The statement that eating MSG can make people lose their hair is not true and should not be taken lightly. The main component of MSG is monosodium glutamate, which does not have the side effect of causing hair loss, and normal intake is not harmful to the body. Although MSG does not cause hair loss, it contains more sodium, and excessive intake can cause certain effects on other aspects of the body. Monosodium glutamate can be transformed into glutamine and tyrosine in the human body through decomposition, both of which are important components of human protein. Hair contains a large amount of protein, which is needed to support the growth of hair. If the protein synthesis is insufficient, it may lead to split ends, breakage or even fall off, affecting regeneration. Therefore there is no conflict between monosodium glutamate and hair growth, and hair loss will not occur as a result of eating MSG. If hair loss occurs, you need to consider that it may be affected by other problems, such as high oil secretion, poor head cleaning, etc., and requires targeted treatment. Although MSG does not cause hair loss, MSG contains a large amount of sodium, and excessive intake can affect other systems in the body. Sodium can increase sympathetic activity, affect the auto-regulatory mechanism of small arteries, and compromise kidney metabolism, thus increasing the risk of developing hypertension. In addition, there is a possibility that it may affect the absorption of calcium, leading to osteoporosis. Therefore, it is not advisable to consume MSG in excess and to control the intake of other seasonings so as to control the daily sodium intake to avoid exceeding the limit.
