I've just assumed that because it is a tea it's calorie free. But I drink a lot of it, so I'm wondering if perhaps some of the starches or sugars disolve in the water, or just the flavour? How many calories does it have?

I'ev also read that roasted corn tea (and also roasted barley tea) have health benifits. But I've searched google and I cant find what exactly those health benifits are ment to be.
