Put Down the Pomegranate Juice

Poor pomegranate. Anti-oxidants don't work.

Few medical remedies have a more sterling reputation than that assortment of foods, pills, and general life maneuvers known collectively as "antioxidants." At last, here's something that promises better heart health, improved immunity, a pellucid complexion as well as relief against cancer, arthritis, and the blahs—and it's all-natural! What's not to like?

Well, there is a wee small problem in our ongoing anti-oxidize-athon: As it turns out, we have no evidence that antioxidants are beneficial in humans. (Though if you're a Sprague-Dawley rat, there's hope.) In fact, as Emily Anthes wrote last year in Slate, the best available data demonstrate that antioxidants are bad for you—so long as you count an increased risk of death as "bad."
