PurePlant Nation (now available streaming on Netflix) shows how we can live healthier, happier lives through a plant-based diet. Pure and simple. It actually presents facts and studies including The China Study. Here's a description of that study as it appears on Wikipedia:
The China Study is a book by T. Colin Campbell, Jacob Gould Schurman Professor Emeritus of Nutritional Biochemistry at Cornell University, and his son Thomas M. Campbell II, a physician. It was first published in the United States in January 2005 and had sold over one million copies as of October 2013, making it one of America's best-selling books about nutrition.[2
The China Study examines the relationship between the consumption of animal products (including dairy) and chronic illnesses such as coronary heart disease, diabetes, breast cancer, prostate cancer and bowel cancer.[3 The authors conclude that people who eat a whole-food, plant-based/vegan diet—avoiding all animal products, including beef, pork, poultry, fish, eggs, cheese and milk, and reducing their intake of processed foods and refined carbohydrates—will escape, reduce or reverse the development of numerous diseases. They write that "eating foods that contain any cholesterol above 0 mg is unhealthy."[4
Dr Campbell wrote this book well into his 70's, thus helping to qualify this blog post appearing in Senior Focus.
One of a number of things that helped me switch over to a plant-based diet, cutting out all animal and dairy products, was saying to myself those three magic words "Up until now" in response to my inner-voice that had been telling myself forever that "I love meat, I need meat, I must have meat, I can't live without meat."
