How Plant-Based to Lower IGF-1?

DESCRIPTION: Those eating vegan had significantly lower IGF-1 levels and higher IGF binding proteins than those just eating vegetarian, suggesting that the more plant-based one's diet becomes, the lower ones risk of fueling growth hormone dependent cancer growth. To review, I started out introducing Nathan Pritikin (http://nutritionfacts.org/video/engineering-a-cure/) and the elegant series of experiments that became part of his legacy (http://nutritionfacts.org/video/developing-an-ex-vivo-cancer-proliferation-bioassay/). They were able to demonstrate the mechanism by which a plant-based diet and exercise could suppress the growth of breast and prostate cancer cells (http://nutritionfacts.org/video/the-answer-to-the-pritikin-puzzle/) and protect against prostate enlargement (http://nutritionfacts.org/video/prostate-versus-a-plant-based-diet/). More on BPH at http://nutritionfacts.org/video/some-prostates-are-larger-than-others/ and specific foods that may help at http://nutritionfacts.org/video/prostate-versus-plants/. I also asked and answered Is It the Diet, the Exercise, or Both? (http://nutritionfacts.org/video/is-it-the-diet-the-exercise-or-both/). We learned that the cancer promoting growth hormone (IGF-1 http://nutritionfacts.org/video/igf-1-as-one-stop-cancer-shop/) seemed to be The Answer to the Pritikin Puzzle (http://nutritionfacts.org/video/the-answer-to-the-pritikin-puzzle/), but why? What is it about plant-based diets that lower IGF-1 levels and increase our body's ability to neutralize IGF-1? Find out in Monday's video-of-the-day Protein Intake & IGF-1 Production (http://nutritionfacts.org/video/protein-intake-and-igf-1-production/).

Have a question for Dr. Greger about this video? Leave it in the comment section at http://nutritionfacts.org/video/how-plant-based-to-lower-igf-1/ and he'll try to answer it!
