Is MSG safe?

"MSG will become stupid when eating too much," "Each MSG is old and fast, and it is not good for the body." ... The rumors about MSG have almost never stopped. With the increasing emphasis on nutrition and dietary health, people are increasingly concerned about MSG. What is MSG? Will it affect human health?

As early as 1907, when Japanese people were eating seaweed soup, they discovered that as long as the soup was evaporated, they would get an umami-tasting substance. Adding it to food could obviously make people feel the umami. This is glutamic acid. sodium. Later, people fermented starch, sugar beet and other raw materials to obtain sodium glutamate, which is often referred to as MSG. The process of producing MSG does not add any chemical raw materials. The monosodium glutamate currently sold on the market is a highly purified fermentation product. According to our national standards, its sodium glutamate content is at least 80%.

Is MSG safe? There are many such discussions and studies at home and abroad. Reviews of authoritative departments such as the FDA, the American Medical Association, the UN Food and Agriculture Organization and the WHO Joint Expert Group on Food Additives show that the use of MSG in food is “without restrictions” and there is no need to worry about its safety.

At the same time, some sounds about the health hazards of MSG have also appeared frequently. Wu Fengying, deputy director of the Institute of Nutrition and Food Safety at the Chinese Center for Disease Control and Prevention, said that during the survey, they found that there is a certain relationship between MSG consumption and overweight among Chinese adult residents. The proportion of people who consume more than one gram of monosodium glutamate per day is 37% of those who are overweight and obese, and 28% less than 1 gram. A total of 2.2 grams of MSG was ingested daily, and the risk of overweight increased significantly. Researchers at North Carolina State University conducted a 5.5-year follow-up survey of the eating habits of 10,000 adults in China. The results showed that people who consumed more than 5 grams compared with those who consumed less than 0.5 grams of MSG per day had a 30% higher chance of being overweight or obese after 5.5 years. Japanese researchers also found that too much MSG may cause people to suffer visual impairment; and since MSG contains sodium, excessive intake may also lead to high blood pressure.

As a seasoning for increasing freshness, it is not a problem for adults to properly intake MSG. Professor Ma Liping, vice chairman of the Guangxi Nutrition Society, said that children and elderly people with chronic diseases such as high blood pressure should not eat monosodium glutamate. Ma Liping also reminded that many people think that chicken is healthier than MSG. In fact, the main ingredient of chicken is still MSG and salt. It is not very relevant to chicken. It is best not to be misled.
