Monosodium Glutamate (MSG)
MSG, also known as monosodium glutamate, is a typical food additive used to enhance and intensify the flavor of savory dishes. It can be present in many processed foods, including canned soups, frozen dinners, and salty snacks. Additionally, it is frequently added to foods at fast food restaurants.
Since a 1969 study on mice revealed that excessive quantities of MSG caused negative neurological effects and impaired growth and development. The blood-brain barrier prevents this additive from entering the brain, therefore it is likely to have little to no impact on the health of the human brain. However, some people do have a sensitivity to MSG and may show signs like headaches, sweating, and numbness after consuming a lot of it. It is advised to avoid MSG in your diet if you feel any negative side effects after taking it. Otherwise, MSG can be safely consumed in moderation without the risk of negative side effects if you can tolerate it.
