The film's narrative is anchored by the independent research of two prominent figures:
: All animal-based products (meat, dairy, eggs) and processed foods, specifically highlighting the avoidance of added oils and refined sugars. Impact and Legacy
Released in 2011, is a landmark American documentary that challenges the modern healthcare paradigm by advocating for a whole-food, plant-based (WFPB) diet . Directed by Lee Fulkerson and produced by Brian Wendel, the film presents the provocative claim that chronic "diseases of affluence"—such as heart disease, type 2 diabetes, and certain cancers—can be prevented, halted, or even reversed through nutrition rather than surgical or pharmacological intervention. Core Arguments and Scientific Foundation
: A former surgeon at the Cleveland Clinic who conducted clinical trials demonstrating that severely diseased heart patients could experience significant recovery and even reversal of arterial plaque simply by removing animal products and oils from their diets.
The title itself serves as a metaphor for choosing the "fork" (preventative nutrition) over the "knife" (surgery as a last resort).
