"Undoctored: Why Health Care Has Failed You and How You Can Become Smarter Than Your Doctor," by William Davis, argues that modern medicine has failed to provide effective solutions for many common health problems, largely due to the influence of pharmaceutical companies and a focus on profit rather than true health. The book advocates for a self-directed approach to health that prioritizes nutrition, specifically a grain-free diet, and addresses other crucial elements like bowel health, nutrient deficiencies, and circadian rhythms. Davis outlines a comprehensive 6-week program that, he claims, can help people reverse a wide range of health conditions and reduce or eliminate reliance on conventional healthcare.
