How much amount of monosodium glutamate is safe to eat?

The acceptable daily intake (ADI) of monosodium glutamate (MSG) is generally considered to be about 0.5 to 1.0 grams per kilogram of body weight, according to the Joint FAO/WHO Expert Committee on Food Additives. For the average adult, this translates to a safe intake of several grams per day. Most studies suggest that moderate consumption of MSG is safe for most people, but some individuals may experience sensitivity or adverse reactions. It's always best to consume it in moderation.
