People taking dietary supplements may, in some cases, be paying to make themselves sick. This video covers folic acid, beta carotene, and green tea supplements. This is the final video of a three-part series on the latest information about the safety of dietary supplements. See Dietary Supplement Snake Oil (http://nutritionfacts.org/video/dietary-supplement-snake-oil) and Heavy Metals in Protein Powder Supplements [Heavy Metals in Protein Powder Supplements] for the first two. For background on the folic acid versus folate story (which may explain any multivitamin breast cancer connection), see Can Folic Acid Be Harmful? (http://nutritionfacts.org/video/can-folic-acid-be-harmful) For more on avoiding esophageal cancer see Poultry and Penis Cancer (http://nutritionfacts.org/video/poultry-and-penis-cancer/), Coffee and Cancer (http://nutritionfacts.org/video/coffee-and-cancer/), and Bacon and Botulism (http://nutritionfacts.org/video/bacon-and-botulism/). For how to boost your absorption of carotenoid phytonutrients like beta carotene see Raw Food Nutrient Absorption (http://nutritionfacts.org/video/raw-food-nutrient-absorption-3/) and Forego Fat-Free Dressings (http://nutritionfacts.org/video/forego-fat-free-dressings/). Pretty scary about green tea supplements, but green tea has a variety of health-promoting properties. Check out my videos about tea (http://nutritionfacts.org/topics/tea/), and hundreds of videos on more than a thousand other topics (http://nutritionfacts.org/topics/).
