Standard American DIet (SAD) is so bad going entirely meat free, dairy free would probably be an improvement, but that’s assuming it’s a move from processed to unprocessed food. However this documentary is terrible, massively biased towards vegan agenda. It is very supportive of sugar, I would not be at all surprised if the filmmakers received funding from the sugar industry. Emotive pictures of babies, mothers, good home folk suffering. The language equally emotive, milk described as pus. A single egg described as bad as five cigarettes. Minimal science. Lots of numbers thrown out without backup. Many quick comments from doctors at eminent institutions, on average 10 to 30 seconds each, edited together to fit the film makers agenda. Watch if you want to learn arguments to back a view towards Veganism/vegetarianism. Nothing wrong with either as a lifestyle choice. Avoid if you are looking for an unbiased informed documentary on nutrition and the part it plays in health.
