My girlfriend got some information from FigureAthlete.com about nutrition that I had a question about. In an article or forum (she didn't say which one) she was told not to eat any deli meat that is packaged in grocery stores because it's processed. What is the logic behind this?
Does that mean that the processing is adding extra or taking away things that aren't necessarily on the ingredients? I understand hot dogs are processed and bad for you, but what about turkey breast?
