Renee's right - they didn't factor in any possible differences between organic vs. non-organic, GM vs. non-GM, what else the men were consuming (refined oils, flours, and sugars, not to mention Avoids). My grandmother never ate a bite of soy in all her 90+ years, but she developed Alzheimer's. She also lived off of decaf coffee and Sugar Smacks. If your diet is lousy all around, it's not accurate to blame soy when you get sick.
