If you would like comprehensive and conclusive studies:
"The China Study" by T. Collin Cambell
The China Study examines more than 350 variables of health and nutrition with surveys from 6,500 adults in more than 2,500 counties across China and Taiwan, and conclusively demonstrates the link between nutrition and heart disease, diabetes, and cancer. While revealing that proper nutrition can have a dramatic effect on reducing and reversing these ailments as well as curbing obesity, this text calls into question the practices of many of the current dietary programs that are widely popular in the West. The politics of nutrition and the impact of special interest groups in the creation and dissemination of public information are also discussed in detail.
"Prevent and Reverse Heart Disease: The Revolutionary, Scientifically Proven, Nutrition-Based Cure" by Caldwell B. Esselstyn Jr.
A powerful call for a paradigm shift in heart disease therapy.
Based on the groundbreaking results of a twenty-year nutritional study by Dr. Esselstyn, a preeminent researcher and clinician, this book illustrates that a plant-based, oil-free diet can not only prevent and stop the progression of heart disease but can also reverse its effects.
The proof lies in the incredible outcomes for patients who have followed Dr. Esselstyn's program, including a number of patients in his original study who had been told by their cardiologists that they had less than a year to live. Within months of starting the program, Dr. Esselstyn's patients began to improve dramatically, and twenty years later, they remain free of symptoms.
