Neurotoxin contamination of the dairy supply doesn’t explain why the association between Parkinson’s disease and skim milk consumption is as strong as the association of whole milk.

Why is a plant-based diet the best for thyroid health? Is the apparent protection of plant-based diets due to the exclusion of animal foods, the benefits of plant foods, or both?

DESCRIPTION: Women suffering with dysmenorrhea who switch to a plant-based diet experience significant relief in menstrual pain intensity and duration.
I've touched on this body of work briefly in Plant-Based Diets For Breast Pain (http://nutritionfacts.org/video/plant-based-diets-for-breast-pain/). Plants that may be especially helpful include flax seeds (Flax Seeds For Breast Pain, http://nutritionfacts.org/video/flax-seeds-for-breast-pain/) and the spice saffron (Saffron for the Treatment of PMS, http://nutritionfacts.org/video/saffron-for-the-treatment-of-pms/ and Wake Up and Smell the Saffron, http://nutritionfacts.org/video/wake-up-and-smell-the-saffron/).
For those unfamiliar with the work of Drs. Ornish and Esselstyn, see, for example, my video Our Number One Killer Can Be Stopped (http://nutritionfacts.org/video/our-number-one-killer-can-be-stopped/) or my blog Heart Disease: There Is A Cure (http://nutritionfacts.org/2011/10/14/heart-disease-there-is-a-cure/).
The vitamin D results were astonishing. See my series justifying my vitamin D recommendations starting with Vitamin D Recommendations Changed (http://nutritionfacts.org/video/vitamin-d-recommendations-changed/) and ending with Resolving the Vitamin D-Bate (http://nutritionfacts.org/video/resolving-the-vitamin-d-bate/).

One of the ways plants help keep platelets in their place may be their aspirin content. See Aspirin Levels in Plant Foods (http://nutritionfacts.org/video/aspirin-levels-in-plant-foods/). Why would a plant make a human drug? It’s so cool, check out Appropriating Plant Defenses (http://nutritionfacts.org/video/appropriating-plant-defenses/).

Is the Standard American Diet really so bad that we could save 100,000 people by just getting up to minimum fruit and veggie recommendations? Even cynics might be surprised: Nation’s Diet in Crisis (http://nutritionfacts.org/video/nations-diet-in-crisis/). Even more plants may cut deaths even more, though. See One in a Thousand: Ending the Heart Disease Epidemic (http://nutritionfacts.org/video/one-in-a-thousand-ending-the-heart-disease-epidemic/).
For more on lowering cholesterol see my video Trans Fat, Saturated Fat, and Cholesterol: Tolerable Upper Intake of Zero (http://nutritionfacts.org/video/trans-fat-saturated-fat-and-cholesterol-tolerable-upper-intake-of-zero/). And it’s never too early to start eating healthier. Check out: Heart Disease Starts in Childhood (http://nutritionfacts.org/video/heart-disease-starts-in-childhood/). Heart disease may be a choice. See: Cavities and Coronaries: Our Choice (http://nutritionfacts.org/video/cavities-and-coronaries-our-choice/).
Berries are the healthiest fruits, shown to maintain our brain power (How to Slow Brain Aging By Two Years http://nutritionfacts.org/video/how-to-slow-brain-aging-by-two-years/) and improve our immune function (Boosting Natural Killer Cell Activity http://nutritionfacts.org/video/boosting-natural-killer-cell-activity/). That’s one of the reasons we want to eat Antioxidant Rich Foods With Every Meal (http://nutritionfacts.org/video/antioxidant-rich-foods-with-every-meal/).

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!
