The reason why women who handle hops start menstruating is because of a phytoestrogen that ends up in beer, called 8-prenylnaringenin (8-PN).

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. This is the fourth in a string of videos on the role plant and animal proteins play in determining levels of the cancer-promoting growth hormone IGF-1 (http://nutritionfacts.org/video/igf-1-as-one-stop-cancer-shop/). See Protein Intake and IGF-1 Production (http://nutritionfacts.org/video/protein-intake-and-igf-1-production/), Higher Quality May Mean Higher Risk (http://nutritionfacts.org/video/higher-quality-may-mean-higher-risk/), Animalistic Plant Proteins (http://nutritionfacts.org/video/animalistic-plant-proteins/), and Too Much Soy May Neutralize Benefits (http://nutritionfacts.org/video/too-much-soy-may-neutralize-plant-based-benefits/). 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/breast-cancer-survival-and-soy/). 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/).
Have a question for Dr. Greger about this video? Leave it in the comment section at http://nutritionfacts.org/video/how-much-soy-is-too-much/ and he'll try to answer it!

DESCRIPTION: Plant-based diets may be protective against multiple sclerosis because IGF-1 may prevent our immune system from eliminating autoimmune cells. This is the third video in a series on understanding the autoimmune theory of cancer outlined in Monday's video Cancer as an Autoimmune Disease (http://nutritionfacts.org/video/cancer-as-an-autoimmune-disease/), followed up with Tuesday's video-of-the-day Clonal Selection Theory of Immunity (http://nutritionfacts.org/video/clonal-selection-theory-of-immunity/). For the story of how dietary manipulation of IGF-1 may affect cancer risk, see 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/). IGF-1 also appears to affect prostate gland growth. See Some Prostates are Larger than Others (http://nutritionfacts.org/video/some-prostates-are-larger-than-others/), Prostate Versus Plants (http://nutritionfacts.org/video/prostate-versus-plants/), and Prostate Versus a Plant-Based Diet (http://nutritionfacts.org/video/prostate-versus-a-plant-based-diet/). Tomorrow we'll finally get around to the star of this video series, The Inflammatory Meat Molecule Neu5Gc (http://nutritionfacts.org/video/the-inflammatory-meat-molecule-neu5gc/).

DESCRIPTION: Organic produce may present less of a food safety risk, given the potential contamination of pesticides with fecal pathogens.
When you hear of people getting infected with a stomach bug like E. coli from something like spinach, it's important to realize that the pathogen didn't originate from the spinach. Intestinal bugs come from intestines. Greens don't have guts; plants don't poop.
So the Salmonella in alfalfa sprout seeds (http://nutritionfacts.org/video/dont-eat-raw-alfalfa-sprouts/) likely came from manure run-off or contaminated irrigation water. But this pesticide angle adds a whole new route for fecal pathogens to pollute produce. Broccoli Sprouts (http://nutritionfacts.org/video/broccoli-sprouts/) are safer, and organic sprouts may therefore be safer still.
Organic foods may also be healthier (see http://nutritionfacts.org/video/cancer-fighting-berries-2/) and don't carry the potential chemical hazards associated with pesticides. See my videos:
• CDC Report on Environmental Chemical Exposure (http://nutritionfacts.org/video/%EF%BB%BFcdc-report-on-environmental-chemical-exposure/)
• Preventing Parkinson's Disease With Diet (http://nutritionfacts.org/video/preventing-parkinsons-disease-with-diet/)
• Can Pesticides Be Rinsed Off? (http://nutritionfacts.org/video/can-pesticides-be-rinsed-off/)
• Pesticides in Chinese Bamboo Shoots (http://nutritionfacts.org/video/pesticides-in-chinese-bamboo-shoots/)
• Plants vs. Pesticides (http://nutritionfacts.org/video/plants-vs-pesticides/)

Normally I wouldn’t make a whole video for such a rare use, but I was so impressed with the results I figured that even if I could help one person in this situation it would be worth it. Reminds me of my videos Treating Gorlin Syndrome With Green Tea (http://nutritionfacts.org/video/treating-gorlin-syndrome-with-green-tea/) and Topical Application of Turmeric Curcumin for Cancer (http://nutritionfacts.org/video/topical-application-of-turmeric-curcumin-for-cancer/).
If oatmeal is so powerful that it can clear up some of the ravages of chemotherapy just applied to the skin, what might it do if we actually ate it? That’s the subject of my next video, Can Oatmeal Help Fatty Liver Disease? (http://nutritionfacts.org/video/can-oatmeal-help-fatty-liver-disease)
Cetuximab is often given for metastatic colorectal cancer. Better to try to prevent the disease in the first place:
• Turmeric Curcumin and Colon Cancer (http://nutritionfacts.org/video/turmeric-curcumin-and-colon-cancer/)
• Phytates for the Prevention of Cancer (http://nutritionfacts.org/video/phytates-for-the-prevention-of-cancer/)
• Stool Size Matters (http://nutritionfacts.org/video/stool-size-matters/)
