This documentary looks at health from the point of view of good nutrition and prevention. It explores the failings of modern medicine, the control that pharmaceutical companies have over scientific publishing and regulators and the health benefits of vitamins and minerals.
They look into the age of food, soil quality, agriculture, genetic modification and many other issues that people should consider when buying things to eat. They explore a few studies (not many unfortunately) where vitamins cured depression, alcoholism and cancer. I think that they needed a bit more science in this video as well as hard facts but documentaries are always trying to push a certain view point. That said, eat your vitamins!
