Many people think that eating too much MSG will cause allergies such as thirst, headache, and palpitations, which means the so-called "Chinese restaurant syndrome" and "MSG allergies". But is eating too much MSG really harmful to health?
Chinese talk show actor Uncle Roger called "MSG the king of cuisine", and once joked that "MSG is said to be unhealthy because Western dishes are difficult to compete with Chinese restaurants that use MSG, so they have to come up with this worst." Therefore, many dishes emphasize "MSG without MSG."
In fact, the U.S. Food and Drug Administration (FDA) announced as early as the 20th century that consumption of normal amounts of MSG is not harmful to the human body, and there is no evidence that MSG consumption is related to any chronic disease. Chen Yiting, a nutritionist at Zhenxing Hospital, said that whether it is actually or research, there is no direct evidence at present that MSG can cause thirst, headache, palpitations and other symptoms.
MSG provides four kinds of sour, sweet, bitter and sausage, but also has the fifth "fresh flavor". Chen Weiting said that MSG is an amino acid, and its academic name is syringe, which is a salted form of amino acid and is not synthesized by chemicals. In the past, MSG could be extracted from chicken, pork, etc., and now it is mostly fermented from sugarcane, beet, cassava and other powders, and extracted from natural foods. After adding water to MSG, it will decompose into wandering saccharic acid and ionic ions, which can feel the delicious smell through the smell receptors in the mouth.
Unappropriate after meals. Other sauces lead toWhy do some people have "Chinese Restaurant Syndrome" physically unsuitable after eating Chinese food? Chen Weiting pointed out that since the cooking does not only use a single flavoring, not only MSG, but also add salt, sauce, etc., if the overall calcification content is taken too much, it may cause symptoms such as malnutrition, vomiting, and headache, which may have short-term effects on the nervous system, so it cannot be blamed for MSG.
Chen Yiting said that he had had an animal experiment and used high doses of MSG to mice through injection, and the neural system and stomach system were indeed affected. However, generally, it is absorbed by the stomach tract and the amount of edible is not high. The top is mostly caused by symptoms such as thirst and head, which affects short time and is not toxic and will not affect the organs. If the content of ginger is too high due to ingredient odors such as sauce, people can drink more water or sugar-free tea to excrete the ginger out of the body.
European Recommendation: The safe use of MSGEuropean Recommendation: The safe use of MSG, the daily intake of MSG should not exceed 30 mg. Chen Weiting pointed out that the MSG consumption in this way is equivalent to 60 kg of adults does not exceed 1.8 grams. In fact, the MSG content is only one-third of the salt. However, when cooking, many people often use salt and MSG, which will cause excessive calcification content to take up too much. People with mental and kidney problems should pay special attention.
Chen Weiting reminds that people with chronic kidney disease, kidney washing, heart failure, hypertension, hydration and other groups should pay special attention to the calves. It is recommended that if the dish uses MSG, it should reduce the amount of salt. It can also be cooked with ingredients such as mushrooms, rice, fish, kohlrabi, etc., or seafood with shells, such as clams, pineapples, etc., which can bring out the natural flavor of the food.
