Free form glutamate (glutamic acid anions) commonly found in everyday foods (such as: mushrooms, seaweed, tomatoes, nuts, beans, meat), is a product of metabolism in the body naturally. Glutamate stimulation of taste buds on the tongue umami receptor, makes us feel delicious. Many foods high in umami glutamate-rich foods.

MSG is safe with respect to the question, in fact, developed countries and international organizations already conclusion:
The US Food and Drug Administration (FDA) 1958 will glutamate as 'generally recognized as safe' (GRAS) ingredients. It is possible to give the United States the safest category of food ingredients, as well as the same category pepper, sugar, vinegar and baking powder.
