Pfft. People will always want to believe there's an easy solution, and so long as there's money to be made selling the products, the companies will keep advertising these things.

I just try not to eat too much of any one thing in my diet (a little difficult at the moment, since it's limited) and try to avoid processed foods. I figure almost everything I eat has been, is, or will be a "super food" at some point for some reason, and anything in moderation shouldn't be too bad, even if it turns out to not be so good for us.
