Here at That's Fit, we're constantly telling you what we think about things, but sometimes it's nice to know what you think. So from time to time, we'll ask you a question. Don't be afraid to speak up -- we love feedback.

When is a food truly super? And when is it just another food with a really great marketing campaign behind it?

In many ways, food is like fashion. Certain items come into vogue ... and they can also lose their popularity. Take eggs for example -- for years they were vilified for cholesterol, now they're seen as an overall healthy food and weight loss aid. The superfood du jour may change -- blueberries, pomegranate, acai and so forth -- but the hype is the same. If you're to believe the advertising, these superfoods are a must for everybody.
