Whey is used as an emulsifier in processed meats[1]. Personally the biggest issue I've noticed with these "bad ingredient" trends is that, 1.) Most issues seem to come from overuse (e.g. drinking too much soda), and 2.) They're easy scapegoats for many issues which have arose in the last ~20 or so years. There's certainly an argument to be made for the recent occurrence of some of these issues being due to increased scrutiny or increased intake of said product. Anecdotally, I know my father is allergic to wheat and corn. My younger brother is (potentially -- last I heard he's testing it) allergic as well. I've had no negative side effects, but I do eat much less processed food and grains than they both do/did. But, again, that's very anecdotal and in no way is it a representation of a larger population. [1] http://www.usdec.org/files/pdfs/6meat.pdf http://www.usdec.org/files/pdfs/6meat.pdf
