Is MSG dangerous to eat?
Largely no — the evidence mostly does not support this claim.
Monosodium glutamate (MSG) is dangerous to eat.
What the evidence shows
Regulators classify MSG as generally safe at normal dietary levels. Controlled studies have not reliably reproduced the symptoms once attributed to it, and reviews have not established that ordinary amounts cause harm in the general population. A small number of people report short-lived sensitivity to large doses, but the broad claim that MSG is dangerous is not supported.
