There's pros and cons to everything. Take frozen meat for instance...known to harbor parasites and more importantly, it denatures and destroys the enzymes. Also totally ruins the meat texture via ice crystals. But...it's better to have it than none. If people steered clear of soy (including oils) and msg, I think they'd be in pretty good shape... but they probably don't know modified food starch has msg in it as well as others.
