DESCRIPTION: To maintain the low IGF-1 levels associated with a plant-based diet, one should probably eat no more than 3-5 servings of soy foods a day.

See Protein Intake and IGF-1 Production (http://nutritionfacts.org/video/prote..., Higher Quality May Mean Higher Risk (http://nutritionfacts.org/video/highe..., Animalistic Plant Proteins (http://nutritionfacts.org/video/anima..., and Too Much Soy May Neutralize Benefits (http://nutritionfacts.org/video/too-m.... For the role soy plays in extending breast cancer survival, see my latest video on the subject Breast Cancer Survival and Soy (http://nutritionfacts.org/video/breas.... I've got two dozen other videos on soy (http://nutritionfacts.org/topics/soy/) and hundreds of others on more than a thousand topics (http://nutritionfacts.org/topics/).
