The Worst Diet for the General American?

I think the worst for the general American is probably like vegan, if I had to say it, I'm good at it. The reason being, I think you could actually make vast majority of diets work because humans are so adaptable. Is an optimized vegan diet better than say an optimized omnivorous diet? Like, no. No. Why not? Because while you can optimize a vegan diet, you can always make something better.
