The main component of monosodium glutamate is sodium glutamate. In addition to being a good seasoning additive, monosodium glutamate can also decompose glutamic acid during digestion, which 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 and muscle spasm. Some people will be anxious and flustered; Some people with sensitive physique may even feel sore bones and muscles. In addition, excessive inhibitory neurotransmitters can also inhibit the secretion of thyroid stimulating hormone in human hypothalamus, thus hindering the development of bones, especially for children. N kinds of people who shouldn't eat MSG eat too much MSG and often feel thirsty. This is because monosodium glutamate contains sodium, and excessive intake will lead to 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. Therefore, infants and nursing mothers should fast or eat less monosodium glutamate. In addition, Japanese researchers believe that long-term excessive consumption of monosodium glutamate may lead to thinning of retina, decreased vision and even blindness. & gt& gt& gt How much MSG should the wet nurse eat less? So, how much monosodium glutamate should be consumed per meal? The researchers suggest that each dish should not exceed 0.5 mg. The severity of the side effects of monosodium glutamate will vary according to one's physique. Therefore, everyone should pay attention to health while enjoying delicious food. Why do people lose their hair? Everyone has it, but some people lose more and some people lose less. And some people will fall off one by one and eventually go bald. What's going on here? Hair has its own life. When it reaches a certain length, it will die of old age and fall off naturally. This is a normal phenomenon. Hair loss in this situation is common to everyone. Abnormal hair loss is because the growth of hair is affected. Hair growth needs nutrition, and nutrition is transported by blood. If a person is ill for a long time, weak, insufficient blood gas and malnourished, his hair will temporarily fall off because of lack of nutrition and poor growth. Such people lose their hair easily and a lot. This may be the reason why some people lose their hair after a serious illness. People use their brains too much, or they are often absorbed and bored, or something happens, which greatly stimulates their brains and sometimes affects the supply and growth of hair nutrition.

Some people encounter things that are too exciting, their brains are strongly stimulated, and their spirits are very abnormal. Sometimes a large piece of hair on their heads falls out overnight.

If you want to know if your hair has lost a lot, there is a very simple "hair pulling experiment"; People can gently pull their hair six to eight times, and then see if more than three hairs are pulled down at a time. If there is, it means that hair follicles are fragile, so pay more attention. Hair loss must be diagnosed as pathological or physiological factors.

If men lose their hair, it is mainly because the hairline and sideburns on the forehead move up, and the hair on the front top is sparse, yellow and soft, which eventually makes the forehead bald or fuzzy; Women lose hair on their heads, and their hair becomes sparse, but it will not fall off completely. Traditional Chinese medicine believes that there are two reasons for this disease: first, blood heat is dry, blood heat is stronger, yin blood is injured, and blood tigers generate wind, which hurts yin blood more. Yin blood can't reach the top to nourish the hair roots, and the hair roots dry or fall off; Second, the spleen and stomach are damp and hot, and spleen deficiency is weak.
