"Hold the MSG," may become a statement of the past if food scientist Steve Witherly is to be believed.Witherly says MSG—aka monosodium glutamate, a sodium salt of glutamic acid, which is a non-essential amino acid—is actually good for you.

That stuff is really powerful. For example, I had a whole-wheat pizza—and my kids hate whole wheat—so I put a little supersalt in the tomato sauce, and they sucked that whole thing down. Broccoli is tremendous if you add butter, garlic, and supersalt," Witherly told Business Insider.In short, Witherly says the oft-maligned MSG is perfectly safe."We had research at UC Davis, when I was there, where we drank tumblers of it at about 25 grams, and nothing happened."Read more on Munchies.
