Just because something is natural and plant-based doesn't mean it's necessarily safe. Those who are pregnant, have gallstones, or are susceptible to kidney stones may want to moderate their turmeric consumption.

https://nutritionfacts.org/subscribe/ This is the last installment of a 6-part video series on the power of spices in general and turmeric in particular. I started out discussing the role spices play in squelching inflammation and free radicals in Which Spices Fight Inflammation? (
http://nutritionfacts.org/video/which-spices-fight-inflammation) and Spicing Up DNA Protection (
http://nutritionfacts.org/video/spicing-up-dna-protection). Then out of the lab into the clinic with attempts to test the ability of turmeric extracts to treat joint inflammation with Turmeric Curcumin and Rheumatoid Arthritis (
http://nutritionfacts.org/video/turmeric-curcumin-and-rheumatoid-arthritis) and Turmeric Curcumin and Osteoarthritis (
http://nutritionfacts.org/video/turmeric-curcumin-and-osteoarthritis). My last video, Boosting the Bioavailability of Curcumin (
http://nutritionfacts.org/video/boosting-the-bioavailability-of-curcumin), discussed ways to improve the absorption of these anti-inflammatory and antioxidant compounds.
I wish there was more science on wheatgrass. I just had that one unhelpful anecdote in my video How Much Broccoli Is Too Much? (
http://nutritionfacts.org/video/how-much-broccoli-is-too-much/) There is good science on flax though. See:
• Flax Seeds For Breast Pain (
http://nutritionfacts.org/video/flax-seeds-for-breast-pain)
• Breast Cancer Survival and Lignan Intake (
http://nutritionfacts.org/video/breast-cancer-survival-and-lignan-intake/)
• Flax and Fecal Flora (
http://nutritionfacts.org/video/flax-and-fecal-flora/)
• Prostate vs. Plants (
http://nutritionfacts.org/video/prostate-versus-plants/)
• A Better Breakfast (
http://nutritionfacts.org/video/a-better-breakfast/)
• Flaxseeds vs. Chia Seeds (
http://nutritionfacts.org/video/flaxseeds-vs-chia-seeds/)
More on gallbladder health can be found in my video Cholesterol Gallstones (
http://nutritionfacts.org/video/cholesterol-gallstones/). And those who are susceptible to kidney stones should try to alkalinize their urine by eating lots of dark green leafy vegetables (but then shouldn't we all :). See Testing Your Diet with Pee & Purple Cabbage (
http://nutritionfacts.org/video/testing-your-diet-with-pee-purple-cabbage/).
Based on this new science on turmeric (lots more to come!), I now try to include it in my family's daily diet.
Have a question for Dr. Greger about this video? Leave it in the comment section at
