re: sports/nutrition bars, and other foods.
You would be best "served" to defer from bars and other supplements/food stuffs with soy products in them. Particularly true for men as soy is a false hormone (pseudo-estrogen). Just put in Soy Poison in your preferred search engine...
Unless you are a menopausal woman desiring hormone replacement therapy, Whey is way better.
Once you start reading ingredients, you'll be disgusted with how prevalent soy is, and the more it is manipulated/processed, the worse for you.
Happy Hunting (in the store aisles too!)
