Q&A With Anahad O'Connor for the New York Times

I recently had the chance to do a Q&A with Anahad O'Connor, nutrition reporter extraordinaire, for the New York Times. Here's the full Q&A. 

And here's his intro:

"Many people can rattle off the names of the most popular vitamins and the foods that contain them in abundance. But understanding exactly what vitamins are and what roles they play in the body is far more complicated. In fact, though scientists recognize that there are 13 vitamins that are essential for good health, there is no real consensus on what they actually do and exactly how much of them we truly need.

Catherine Price, a science journalist, explores these questions and more in a book that was recently released in paperback, called “Vitamania: Our Obsessive Quest for Nutritional Perfection.” Ms. Price traces the history of vitamins from their discovery as lifesaving organic compounds that prevented strange diseases to their ubiquity today in foods, beverages and dietary supplements. Ms. Price sheds surprising light on the mythology surrounding vitamins and explains why even basic advice promoted by experts – like the nutrient requirements for healthy adults known as the recommended dietary allowance, or RDA – may be misguided.

Recently, we sat down with Ms. Price to discuss some of the most common misconceptions about vitamins, the reasons vitamin D testing can be misleading, and which questions you should ask yourself before deciding whether to take a multivitamin. Here are edited excerpts from our conversation."
