inFact—Wheatgrass Juice—Brian Dunning—and Vitamins

Posted in Naturalism, Science, Skepticism by amorphousintelligence on August 30, 2009

My good buddy Brian Dunning has decided to venture out beyond his weekly Skeptoid podcast and start doing a series of short videos (about 3 minutes each) called “inFact.” Here is one in which he points out the foibles of wheatgrass juice being marketed and sold (expensively) as not only a health food, but a “super food.” In the simpler good ol’ days, this ipecac syrup could have been exposed as snake oil. So drink up…bottoms up…and to your…health

The only quibble I have with this is at the end he suggests taking a vitamin pill to get vitamins. (It’s possible he meant if you’re deficient, as his language is a bit ambiguous here.) While that will work, the medical consensus shows that the human body metabolizes most—not all, but most—vitamins best through the foods we eat. (Brain Dunning is, of course, perfectly aware of this, as is evidenced by this excellent essay he wrote on that very topic.) If people (and this is not tough in developed countries like the U.S.) simply eat a daily diversity of grains, vegetables, fruits, dairy, proteins, etc. (i.e. “a well-balanced diet”), and get enough sun light, then if they don’t have a specific medical condition, they are not likely to be vitamin deficient—and hence no need for vitamin supplements. (Your doctor can easily check for vitamin deficiency by drawing a small vile of your blood and testing it.) So save that vitamin-pill money for something more worthwhile than the toilet (if not potentially hypervitaminosis), as that’s exactly where your excess vitamins go when you urinate.
