"Vegan" is more a sociological term, designating people who don't eat (or use) animal products, and that could be for environmental, ethical, animal welfare or health reasons. But, "no meat"is not nutrition. Potato chips and coke might be vegan, it is not nutritious. The Whole Foods Plant-Based diet, without added Sugar, Oil or Salt (SOS), is the nutritionally sound basis for a healthy vegan lifestyle. The focus is on #WFPB without SOS, based on the work of T. Colin Campbell in The China Study.
