People's understanding that monosodium glutamate is harmful to health stems from the belief that monosodium glutamate causes cancer. The main component of monosodium glutamate is sodium glutamate, which will become sodium pyroglutamate at high temperature, and sodium pyroglutamate has carcinogenic effect. In fact, what happens when you eat too much monosodium glutamate 100℃ and heat it for 0.5 hours? To tell you the truth, I really haven't tried it. Is there any other way to eat monosodium glutamate besides cooking as seasoning? How can you eat too much? Rice noodles including chicken, duck and fish can be eaten at will? What about after death? I can eat whatever I want. The harm of monosodium glutamate is mostly caused by improper cooking. For example, if monosodium glutamate is put too early, it will be decomposed into sodium pyroglutamate at high temperature, which will not only lose its flavor, but also cause cancer. Cooking with some foods that are too acidic and too alkaline will also make the food unpalatable.

Healthy consumption of monosodium glutamate and chicken essence, please put less in life, because it contains more sodium ions, and excessive intake is likely to pose a threat. In addition, try not to add monosodium glutamate or chicken essence to the delicious ingredients. It is worthy of recognition to urge people to start to examine whether their diet structure will bring health hazards to themselves and their families. But it has also created a group of fast-paced "health experts", adding insult to injury to the hearsay that "this is inedible and harmless". I personally worked in a monosodium glutamate factory for several years, and monosodium glutamate is a quite safe condiment, at least more reliable than ordinary chicken essence or some condiments. The United Nations Food and Agriculture Organization has not stipulated the intake of monosodium glutamate.

Monosodium glutamate is decomposed by the human body into glutamic acid, which is catalyzed in brain tissue and becomes an inhibitory neurotransmitter, showing dizziness, headache, drowsiness, muscle spasm and anxiety. Moreover, too many inhibitory neurotransmitters will also inhibit the body's grasp of the dosage of monosodium glutamate. Excessive consumption of monosodium glutamate will increase the intake of sodium and may disturb the balance of neurotransmitters in human body. Excessive intake of monosodium glutamate can lead to drowsiness, fatigue, palpitation and anxiety, affecting the balance of amino acids, especially for children.
