High-fresh monosodium glutamate is not only a good assistant for seasoning, but also can decompose glutamic acid in the process of digestion, and glutamic acid is converted into inhibitory neurotransmitters 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.
We should know that glutamic acid is a normal metabolic substance in human body, and it plays an important role in human metabolism, such as synthesizing protein needed by human body, participating in the metabolism of protein and carbohydrate in brain, and promoting the oxidation process. It is an active component in brain tissue metabolism and an amino acid that can be used by brain cells.
