Really? You never work with base at all or any lowfat no fat milk products? Cottage cheese, yogurt, etc in lowfat versions often have milk solids with MSG. Nothing in the entire kitchen with carrageenan, guar gum, and/or locust bean gum? Better check those seasoning blends, Ranch dressing packets, extracts and other flavorings. No hydrolized products at all? Get any fruits or veggies that are waxed?
No tomatos? No fish sauce? No soy Sauce? No ultra pasteurized cream?
Hey I'm not suggesting that you start dumping accent on every thing but I'd place a fair wager your using a bit more MSG and glutamate than you might think.
If MSG is sooooo bad then why are there so darn many Asians that live a long healthy life?
More importantly if you feel so strongly about it why are you knowingly using it at all?
