This book details the peer-reviewed scholarly scientific research about the impact of diet and nutrition on disease rates. The scientific literature consistently reports that following a whole-foods plant-based diet prevents the diseases associated with affluent societies (heart disease, cancer, diabetes, etc). The most interesting topic was learning the facts behind the huge meat, dairy, and egg industries who have huge money at their disposal to mislead the public about diet implications on health.
You owe it to your health to read this book and discover the true scientific facts surrounding diet and health, I think it would be the single most important step to living a long and disease-free life.
