People equate the glutatamic acid in it to MSG, which is not technically true. they're chemically different HOWEVER I'm not convinced that there couldn't be some heavy processing with Bragg's that may form MSG, so I need to research this. Also, some people throw a fit over the HCL used to neutralize the soy, but your stomach is chock full of HCL. Finally, I *do* agree that soy should be consumed in moderation, and like any processed food, Bragg's does have preservatives and has to use heat, pressure and chemicals in it's treatment. But ultimately, it's a better protein source than the average soy sauce. However, there may be better alternatives. I'll look into this, and thanks for brining it up.

*The amino acids arginine , methionine and phenylalanine are considered essential for reasons not directly related to lack of synthesis. Arginine is synthesized by mammalian cells but at a rate that is insufficient to meet the growth needs of the body and the majority that is synthesized is cleaved to form urea. Methionine is required in large amounts to produce cysteine if the latter amino acid is not adequately supplied in the diet. Similarly, phenylalanine is needed in large amounts to form tyrosine if the latter is not adequately supplied in the diet.
