Is MSG really bad for your health?
Glutamate is one of the many amino acids (building blocks of protein) found naturally in the body. Glutamate may be naturally present in some protein-rich foods, such as cheese, milk, meat, fish and several different vegetables. Monosodium glutamate (MSG) levels are high especially in foods such as tomatoes, mushrooms and Parmesan cheese. Thus, it is clear that consuming MSG within the allowed limit is not bad for your health.
Findings of one study concluded that MSG is safe, although some people who consume more than three grams of the substance may experience symptoms such as headache or drowsiness. The ideal serving of MSG should be less than 0.5 grams in food.
The Food and Drug Administration (FDA) classifies MSG as “generally recognized as safe,” just like sugar and baking soda. The FDA also claims that the body metabolizes MSG exactly like it metabolizes natural glutamate.
