One of the main themes of these columns boils down to the notion that healthcare is not medicine and that this is the major mistake that needs fixing. I am basically a student of T. Colin Campbell and his Whole Foods Plant-Based nutrition, available also as a certificate course through the T. Colin Campbell Center for Nutritionstudies. His work was foundational to the modern plant-based nutrition movement, and it pays to go back to the source. One of his tenets is that he believes we could cut medical costs by 70-80% if we all adopted a Whole Foods, Plant-Based diet. He coined that term specifically to distinguish it from veganism or vegetarianism, which are not about nutrition but about ethics. Veganism is secular ethics, as in animal welfare and environmental concerns. Vegetarianism is predominantly a matter of religious ethics in Hinduism, Jainism, Buddhism, and some Christian and Jewish sects. Whole Foods, Plant-Based nutrition is about nutrition. After he found the basic evidence that plant-based proteins are healthier than animal-based proteins, Campbell focused the rest of his life on researching and formulating a concept of nutrition that was simple and understandable in the end. His conclusion is what matters here – nutrition is the key factor in health, and being healthy is simply more enjoyable and more economical than fighting disease.
