When asked this question, are you also stunned?

Don't talk about eating monosodium glutamate. It seems that you don't see monosodium glutamate very often now. And all that comes to mind is negative news.

MSG can cause hair loss, MSG can kill sperm, and MSG can cause cancer ~

How can such a poison be eaten? Today, Xiao Miao is going to clear the name of MSG today. It is really not what everyone said, but it is actually a "good" person.

First, the three major rumors of crushing monosodium glutamate

When cooking, if you don't put monosodium glutamate, do you always feel a little less "delicious"? Every time Xiao Miao wants to cook, she will be told by her father to eat so much monosodium glutamate and be careful of hair loss. My little hands are shaking.

1 alopecia

First of all, we should make it clear that there are two common reasons for hair loss. One may be caused by genetic factors, for example, your grandfather or father has hair loss; Second, the recent excessive pressure has led to the disorder of secretion in the body, causing hair loss.

The main component of monosodium glutamate is sodium glutamate, which combines with zinc in human blood and will take away a lot of zinc. In the case of zinc deficiency, hair loss may occur. But this does not mean that hair loss must be caused by eating monosodium glutamate. At present, there is no corresponding data and theory to support it.

2. Sperm killing

In addition to hair loss, what's more, it means that if you eat too much monosodium glutamate, the quality of things made by men's younger brothers will drop. In order to verify whether monosodium glutamate has an effect on fertility-related organs, the European Food Safety Agency has conducted a rat experiment. The experimental results showed that even if the mice ingested more than the safe dosage of sodium glutamate, there were no toxic pathological changes to reproductive and developmental organs.

3. Carcinogenesis

Not long ago, there were rumors on the Internet that monosodium glutamate would form sodium pyroglutamate when the temperature exceeded 100℃, which was carcinogenic. It has been suggested that monosodium glutamate should be added before cooking to reduce the risk of cancer.

A small part of monosodium glutamate in monosodium glutamate can indeed be converted into sodium pyroglutamate by high-temperature cooking, but the proportion is very small, and the impact on the human body is almost negligible. The role of adding monosodium glutamate before cooking can only make the umami taste more prominent, not reduce its carcinogenicity.

Second, chicken essence is healthier than monosodium glutamate?

Speaking of "refreshing", in addition to monosodium glutamate, we have to mention the most powerful "home" of monosodium glutamate over the years-chicken essence. Chicken essence seems to have a word "chicken" from its name, which has something to do with animals and feels "tall". But chicken essence also contains glutamic acid, strictly speaking, it should be the PLUS version of monosodium glutamate.

Don't believe it? Turn over the chicken essence at home and look at the ingredient list. In the ingredients, you can see that the beginning is sodium glutamate, and the chicken essence is just more chicken powder than monosodium glutamate. Some cheap chicken essence and even chicken powder are not added, but are prepared by various food additives, which has little to do with chicken. Even if it contains chicken ingredients, it appears at the back of the ingredient list.

Therefore, chicken essence and monosodium glutamate are both used to make dishes taste more delicious when cooking, and there is not much difference between them.

3. What is the safe intake of monosodium glutamate?

Although monosodium glutamate does not cause cancer, like salt, it also contains sodium. Excessive consumption will undoubtedly cause vascular damage and may cause some intravascular diseases. Associate Professor Zhou Yulin of Nanjing Agricultural University said that although there are few cases of brain injury caused by excessive consumption of monosodium glutamate, it may be necessary to guard against excessive inhalation of sodium, which will harm human health.

According to the opinions of dietary residents in China, the daily sodium intake of each person should be less than 6g, and regarding the intake of glutamic acid and other salts, the European Security Agency gives us a formula: 30mg per kilogram of body weight, for example, 50 kg of women, the daily intake limit is1.5g.

Four, who don't eat monosodium glutamate?

MSG has little effect on the body, but for women during lactation and pregnancy, MSG should be eaten as little as possible, and infants of three months should not eat MSG. Because many organs and hair surfaces of children are not mature, it is impossible for them to fully digest these substances, which may cause discomfort if they accumulate in the body for a long time. Therefore, these people do not recommend eating monosodium glutamate.

In recent years, monosodium glutamate has been "hacked" because of rumors, and it has carried a lot of pots for no reason. The invention of monosodium glutamate is to satisfy people's appetite, and to use monosodium glutamate properly, which is still in the range of healthy diet.
