What the Health is a 2017 American documentary film which critiques the health effects of meat, dairy product and egg consumption, and questions the practices of leading health and pharmaceutical organizations. It also advocates for a plant-based diet. It has been criticised for scientific inaccuracies.

Cowspiracy has been criticized for asserting that animal agriculture is the primary source of greenhouse gas emissions and environmental destruction, with other sources assessing the impact as being less than is stated in the film.

Juan Pascual, a veterinarian, animal health expert, and author of the book Razones para ser omnívoro (Reasons to be an omnivore) points out that “The production is funded by the Vogt Foundation, whose aim is to promote a plant-based diet.

“From a purely scientific point of view, the study is full of methodological errors“, – Juan Pascual comments – “For the first four weeks, the food given to the study participants is controlled, but after that, each participant cooks their food, making the study inaccurate.
