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!

How should we parse the conflicting human data on aspartame (Nutrasweet) intake and non-Hodgkin’s lymphoma, multiple myeloma, leukemia, and pancreatic cancer?

What about the noncancer effects on the brain? See my video Aspartame and the Brain(http://nutritionfacts.org/video/Aspartame-and-the-Brain).
What about Splenda? Got a video on that too: Effect of Sucralose (Splenda) on the Microbiome (http://nutritionfacts.org/video/effect-of-sucralose-splenda-on-the-microbiome).
Is there any nontoxic low calorie sweetener? Erythritol is probably the best candidate: Erythritol May Be a Sweet Antioxidant (http://nutritionfacts.org/video/erythritol-may-be-a-sweet-antioxidant/), though we should probably get away from intense sweeteners, artificial or not. See, for example, Unsweetening the Diet (http://nutritionfacts.org/video/unsweetening-the-diet/).
More the potential adverse effects of drinking diet soda in Does Diet Soda Increase Stroke Risk as Much as Regular Soda? (http://nutritionfacts.org/video/does-diet-soda-increase-stroke-risk-as-much-as-regular-soda).
How about this for a calorie reduction strategy instead: Eating More to Weigh Less (http://nutritionfacts.org/video/eating-more-to-weigh-less/).

DESCRIPTION: For accessible cancers such as skin, mouth, and vulva, the spice turmeric can be applied in an ointment. Note: there's an image of ulcerating breast cancer from 3:03 to 3:09 that viewers may find disturbing.
The colon cancer video I refer to is my last video, Turmeric Curcumin and Colon Cancer (http://www.nutritionfacts.org/turmeric-curcumin-and-colon-cancer).
More on what this golden spice can do in:
• Which Spices Fight Inflammation? (http://nutritionfacts.org/video/which-spices-fight-inflammation/)
• Spicing Up DNA Protection (http://nutritionfacts.org/video/spicing-up-dna-protection/)
• Turmeric Curcumin and Rheumatoid Arthritis (http://nutritionfacts.org/video/turmeric-curcumin-and-rheumatoid-arthritis/)
• Turmeric Curcumin and Osteoarthritis (http://nutritionfacts.org/video/turmeric-curcumin-and-osteoarthritis/)
There are ways of Boosting the Bioavailability of Curcumin (http://nutritionfacts.org/video/boosting-the-bioavailability-of-curcumin/) to get it into our blood stream.
Some should be cautious about turmeric use, though. See Who Shouldn't Consume Curcumin or Turmeric? (http://nutritionfacts.org/video/who-shouldnt-consume-curcumin-or-turmeric/)

DESCRIPTION: Antioxidant intake from foods (not supplements) is associated with lower cancer risk.
But should we take a multivitamin? See Should We Take a Multivitamin?(http://nutritionfacts.org/video/should-we-take-a-multivitamin) :)
What about fish oil supplements? Is Fish Oil Just Snake Oil? (http://nutritionfacts.org/video/is-fish-oil-just-snake-oil)
I recently covered how and why we should strive to eat antioxidants with every meal in an important three-part series:
1. Minimum "Recommended Daily Allowance" of Antioxidants (http://nutritionfacts.org/video/minimum-recommended-daily-allowance-of-antioxidants/)
2. How to Reach the Antioxidant "RDA" (http://nutritionfacts.org/video/how-to-reach-the-antioxidant-rda/)
3. Antioxidant Rich Foods With Every Meal (http://nutritionfacts.org/video/antioxidant-rich-foods-with-every-meal/)
Preferentially getting one's nutrients from produce not pills is a common theme in the nutrition literature. See, for example:
• Are Iron Pills Good for You? (http://nutritionfacts.org/video/are-iron-pills-good-for-you/)
• Can Folic Acid Be Harmful? (http://nutritionfacts.org/video/can-folic-acid-be-harmful/)
• Produce, Not Pills to Increase Physical Attractiveness (http://nutritionfacts.org/video/produce-not-pills-to-increase-physical-attractiveness/)
• Greens vs. Glaucoma (http://nutritionfacts.org/video/greens-vs-glaucoma/)
• Cranberries versus Cancer (http://nutritionfacts.org/video/cranberries-versus-cancer/)
• Prunes vs. Metamucil vs. Vegan Diet (http://nutritionfacts.org/video/prunes-vs-metamucil-vs-vegan-diet/)
• Optimal Phytosterol Source (http://nutritionfacts.org/video/optimal-phytosterol-source/)
Antioxidants may also slow aging (http://nutritionfacts.org/videos/mitochondrial-theory-of-aging/), reduce inflammation (http://nutritionfacts.org/video/anti-inflammatory-antioxidants/), improve digestion (http://nutritionfacts.org/video/bulking-up-on-antioxidants/), and help prevent COPD (http://nutritionfacts.org/video/preventing-copd-with-diet/). So where are antioxidants found? See my series that starts with Antioxidant Content of 3139 Foods (http://nutritionfacts.org/video/antioxidant-content-of-3139-foods/) and Antioxidant Power of Plant Foods Versus Animal Foods (http://nutritionfacts.org/video/antioxidant-power-of-plant-foods-versus-animal-foods/).
What about the role of antioxidants in other leading causes of death? That's the subject of my next video, Food Antioxidants, Stroke, and Heart Disease.

Besides any hormonal effects, Is Tea Tree Oil Safe? (http://nutritionfacts.org/video/is-tea-tree-oil-safe). That was the topic of my last video if you missed it.
Here’s the link to the video I referred to about lavender: Lavender for the Treatment of Generalized Anxiety Disorder (https://nutritionfacts.org/video/lavender-for-generalized-anxiety-disorder).
Abnormal hairiness (hirsutism) may also be a sign of PCOS, polycystic ovary syndrome. I touched peripherally on the benefits of marjoramin Benefits of Marjoram for Polycystic Ovary Syndrome (PCOS) (https://nutritionfacts.org/video/benefits-of-marjoram-for-polycystic-ovary-syndrome-pcos), and on spearmint tea for PCOS in Enhancing Athletic Performance with Peppermint (https://nutritionfacts.org/video/enhancing-athletic-performance-with-peppermint), but the deepest dive I’ve done so far is Best Foods for Polycystic Ovary Syndrome (PCOS) (https://nutritionfacts.org/video/best-foods-for-polycystic-ovary-syndrome-pcos) if you’re interested.

So excited to get back to this after all these years. Here’s the original series, which gives tips on how to find the stuff:
• Amla Versus Cancer Cell Growth (https://nutritionfacts.org/video/amla-versus-cancer-cell-growth)
• Amla Versus Cancer Cell Invasion (https://nutritionfacts.org/video/amla-versus-cancer-cell-invasion/)
• Amla Versus Diabetes (https://nutritionfacts.org/video/amla-versus-diabetes/)
What else is super-duper antioxidant packed? See my videos Antioxidant Power of Plant Foods vs. Animal Foods (https://nutritionfacts.org/video/antioxidant-power-of-plant-foods-versus-animal-foods) and Antioxidant Content of 3,139 Foods (https://nutritionfacts.org/video/antioxidant-content-of-3139-foods/).
Stay tuned for the thrilling conclusion in my next video Amla vs. Drugs for Cholesterol, Inflammation, and Blood-Thinning (http://nutritionfacts.org/video/Amla-vs-Drugs-for-Cholesterol-Inflammation-and-Blood-Thinning).
No matter how well it works, though, one can essentially eliminate risk of heart disease with a healthy enough diet. See my overview video How Not to Die from Heart Disease (https://nutritionfacts.org/video/how-not-to-die-from-heart-disease). But if after doing everything right your cholesterol is still too high, amla may help.

DESCRIPTION: Farmed Atlantic salmon, the kind of salmon most commonly found in restaurants and supermarkets, may be the single largest source of toxic dietary pollutants.
If you missed the first two videos in this three part series, I reviewed the existing links between seafood and diabetes risk in Fish and Diabetes (http://nutritionfacts.org/video/fish-and-diabetes) and explored this concept of our own body fat as a reservoir for disease-causing pollutants in Diabetes and Dioxins (http://nutritionfacts.org/video/diabetes-and-dioxins).
More on hexachlorobenzene in my video Food Sources of Perfluorochemicals (http://nutritionfacts.org/video/food-sources-of-perfluorochemicals/).
Our body has a tougher time getting rid of some toxins than others:
• How Fast Can Children Detoxify from PCBs? (http://nutritionfacts.org/video/how-fast-can-children-detoxify-from-pcbs)
• How Long to Detox From Fish Before Pregnancy? (http://nutritionfacts.org/video/how-long-to-detox-from-fish-before-pregnancy/)
• The Wrong Way to Detox (http://nutritionfacts.org/video/the-wrong-way-to-detox/)
The best way to detox is to stop toxing in the first place.
