Dr. William Davis, author of the best-seller “Wheat Belly,” argues for patient empowerment in a new book, “Undoctored: Why Healthcare Has Failed You and How You Can Become Smarter Than Your Doctor." Dr. Davis tells the story of his transformation from a successful interventional cardiologist to an outspoken critic of medical orthodoxy; Why does he urge people to eschew not only wheat, but all grain products? What’s wrong with gluten-free baked goods? Why take issue with mainstream nutritionists who urge “moderation”? What’s meant by “undoctoring”? Why has the term “healthcare” become an oxymoron? Why is cholesterol oversold as a predictor of heart risk? Can heart disease be managed without statins? Are coronary stents overdone? Dr. Davis highlights the benefits of a unique probiotic—lactobacillus reuteri—and offers a recipe for a gut-repleting yogurt that restores youthful appearance, strengthens bones, and combats muscle wasting. What role for dietary supplements? For exercise? Why follow Dr. Davis’ call to become an “unpatient”?
