William R. Davis is a Milwaukee-based American cardiologist and author of health books known for his stance against so-called "modern wheat", which he labels a "perfect, chronic poison". His book Wheat Belly became a New York Times bestseller within a month of publication in 2011. Stating all modern wheat, which he refers to as "Frankenwheat", is toxic and addictive as many drugs, and makes you want to eat more food especially junk foods in particular. In an appearance on the The Dr. Oz Show he said, "The wheat of today is nothing like the wheat of 1960, 1950—that is, the wheat that our moms or grandmothers had—so it has been changed. This new crop has implications for human health that were never been anticipated. So this is appropriate for nobody, no human, nobody in this audience, should be eating this modern creation of genetics research."  The book inspired analyses which compare Davis' conclusions with the current evidence-base published in the established scientific literature.
