Forks Over Knives is a 2011 American documentary film which argues that avoiding animal products and ultra-processed foods, and instead eating a whole-food, plant-based diet (whole grains, legumes, tubers, vegetables, and fruits), may serve as a form of chronic illness intervention.

"[13] Loren King of The Boston Globe gave it three out of four stars and remarked that "what An Inconvenient Truth did for global warming, Lee Fulkerson's persuasive documentary does for a vegan diet".

"[14] Jeannette Catsoulis of the New York Times described it as making "a pedantic yet persuasive case for banishing meat and dairy from the dinner table," while also being a "trudge through statistics, graphs and grainy film of cholesterol bubbles and arterial plaque.

"[15] Sean O'Connell of The Washington Post gave the film two out of four stars and argued that it is "an interesting and informative health lecture that's sandwiched into a dry, repetitive documentary" and said that "it's desperately in need of charisma, humor or personality to balance the steady stream of scientific facts we're asked to absorb".

"[17] Corey Hall of the Metro Times gave the film a "C" and stated that "while it's impossible to dispute the basic premise that eating more vegetables is good for you, Forks adopts a staunch anti-meat and -dairy stance that leaves the door open for criticism.
