Your lack of punctuation alarms me. The typical American "diet" is not horrible compared to the rest of the world at large. Saying, "the rest of the world," implies that our diet is horrible to those who are starving, malnourished, and any number of other things that don't fit into a comparison. What I will grant you is that the typical American indulgence is typically more extreme than other parts of the world, strictly because of the availability of such things.
This video, though, is very obviously a load of porpoise hork. You'll notice there are no endorsements from the AMA or any other major medical association, and further that the big tag line is, "we can turn cancer growth on or off by controlling..." Obviously, that's meant to catch the helpless meat eating masses, like us, by surprise. Unfortunately, I'm willing to be the farm (the dairy, meat-producing farm) that for every example they are willing to give (or openly lie about - thank you to whomever pointed out that diabetes isn't a curable disease) where plant-based dieting saved the world, we could all find equal evidence that balanced, animal-based proteins and fats did the same. It's hippy agenda (apologies in advance to those who take that on the chin) and nothing more.
