Monopotassium glutimate

  • 6

A few days ago, while shopping, I picked up some cans of "MSG-free" cream of mushroom soup that a confrere wanted for a casserole. When I got home, I read the ingredient list and found that it contained monopotassium glutimate.
MSG is an "excitotoxin" that can cause neurological damage if it crosses the brain blood barrier. Does anyone know if monopotassium glutimate causes similar damage?

  1. it's an MSG alternative, but it's still a flavor enhancer derived from glutamic acid. if you're at all sensitive to MSG, you might be better off avoiding it. HOWEVER, i haven't seen any dedicated research about it, i'm just thinking the conservative approach is best until you have more information.

    1. any derivative of glutamate is an excitotoxin and it's getting harder and harder to avoid this stuff in commercially prepared foods. even in fine dining, this fixation with 'umami' is all about the mouth detecting glutamic acid. you're right in avoiding this POISON.

      1. Try reading this to put your mind at rest: http://www.guardian.co.uk/lifeandstyl... but if you are concerned about Glutamates then you need to lay off a lot of natural foods that contain them - cheese and tomatoes for example.

          Thanks, Phil. That's very enlightening. I must say, though, that I don't like the taste of monosodium glutamate. It tastes metallic to me. The naturally-occurring glutamates don't seem to set me off.

        2. Wow, that's totally sneaky. Thanks for the heads up!
