From en.wikipedia.org:
Forks Over Knives is a 2011 American documentary film directed by Lee Fulkerson, an American independent filmmaker. The film examines the \"profound claim that most, if not all, of the degenerative diseases that afflict us can be controlled, or even reversed, by rejecting our present menu of animal-based and processed foods,\" principally by tracing the careers and research of American physician Caldwell Esselstyn and professor of nutritional biochemistry T. Colin Campbell.
The film gives an overview of the 20-year China-Cornell-Oxford Project that led to Professor Campbell\'s findings, outlined in his book, The China Study (2005), that a number of diseases can be linked to the Western diet of processed and animal-based foods. Among the diseases the film links to the Western diet are coronary disease, diabetes, and cancer.
