Transcript: Antioxidant Vitamin Supplements
In my 2007 annual review I went nuts over nuts. Cuts our risk of dying from out number one killer disease in half with some expensive miracle drug? No, it was a handful of nuts every day. Scientists suspect that the healthfulness of nuts is in part because of their vitamin E content. So why not just forget the nuts and take the vitamin E directly? Who thinks scientists discovered that’s a bad idea? Who thinks, well it probably won’t hurt, but probably won’t help either? And finally, who thinks vitamin E supplements are a good idea? According to this landmark review in the Journal of the AMA, vitamin E supplements increase all-cause mortality, meaning if you take vitamin E supplements you live, on average, a shorter life. You’re in effect paying to live a shorter life
Same study, but this time vitamin A. Who says vitamin A supplements also decrease your lifespan? How many say: doesn't really affect it one way or another? How many say it makes you live longer? Vitamin A supplements, decrease your lifespan. Ever since Arctic explorers started dying from vitamin A overdoses after eating polar bear liver, the safe upper limit of intake has continued to drop, and indeed those taking vitamin A supplements also live shorter lives.
What about the plant-based source of vitamin A, beta carotene? Who says shorter life? Who says neither shorter nor longer? Who says longer life? Nope, shorter. With two notable exceptions we should try to get nutrients from produce, not pills.
