Americans love fads.

That's why there's a new designated "superfood" popping up each season which supposedly has some incredible properties.

What exactly is a superfood?

Naked Health defines it as, “any edible natural item (plant or animal) that contains exceptionally high levels of a certain nutrient that supposedly carries specific health benefits for preventing or fighting disease.”

These foods are certain to have some benefits, but it's how they're marketed that makes them rise to the top of the heap. A nice, healthy apple doesn't have the same ring to it as an anti-oxidant rich acai berry.
