Looking for Common Ground

After reading waaaay too many articles on paleo diet vs. veganism, I thought I'd make a list of what paleo-dieters and vegans agree on:

• Sugar is bad.
• Green vegetables are good.
• Anecdotes trump data.
• Confounding factors can be ignored.
• The Other Side is full of pseudoscientists and, on top of that, they stereotype people.

Can't both sides lose?

As for what the next food fad will be, I will quote Arthur C. Clarke:

I have no idea what it will be, and am in no great hurry to find out.
