The China Study: The Most Comprehensive Study of Nutrition Ever Conducted (T. Colin Campbell PhD, Thomas M. Campbell MD)
Absolutely mind-blowing. If you have not read this book, you should! It's long, but don't let that deter you. It is jam packed full of potent information on nutrition and its effects on the body backed by rigorous scientific studies and analysis. Do what you want with the knowledge that the Campbells have to offer but please do expose yourself to it in some shape or form. It does err heavily toward what some people may call conspiracy theories, but the underlying research is rock solid. Highly recommend!
