DESCRIPTION: The reason animal proteins trigger the release of the cancer-promoting growth hormong IGF-1 more than plant proteins may be because the relative ratios of amino acids in animal proteins more closely resembles our own. I introduced the tinker toy analogy in yesterday's video-of-the-day Protein Intake & IGF-1 Production (http://nutritionfacts.org/video/protein-intake-and-igf-1-production/). I hope it makes sense! For those who haven't been following along, see IGF-1 as One-Stop Cancer Shop (http://nutritionfacts.org/video/igf-1-as-one-stop-cancer-shop/) for the reason we're so concerned about IGF-1 levels. See my videos The Answer to the Pritikin Puzzle (http://nutritionfacts.org/video/the-answer-to-the-pritikin-puzzle/) and How Plant-Based to Lower IGF-1? (http://nutritionfacts.org/video/how-plant-based-to-lower-igf-1/) to learn about the role diet can play. If the reason animal proteins raise IGF-1 levels is because of their resemblance to our own proteins, what about the few plant proteins that just coincidently happen to have amino acid ratios similar to human and other animal proteins such as soy? Great question! That's the subject of the next few videos starting with tomorrow's video-of-the-day Animalistic Plant Proteins (http://nutritionfacts.org/video/animalistic-plant-proteins/).

Have a question for Dr. Greger about this video? Leave it in the comment section at http://nutritionfacts.org/video/higher-quality-may-mean-higher-risk/ and he'll try to answer it!
