I honestly have no idea which is better for you. My mom uses honey in her coffee, too.

And it
seems like it would be better for you than sugar, but I don't know...
I've heard about Stevia, but I've also heard that Stevia is bad for you. I've always been a fan of Splenda (for the great taste and 0 calories)...but obviously, that can't be good for you either. Right now, I'm not consuming much sweetener at all... but in my green tea, I'm still using
Sugar in the Raw-- the brown kind grown in Hawaii (that doesn't involve using bone char to make it white

).
I have no idea what's best for you in the long run though. I guess minimizing your sugar intake would probably be the easiest thing to do...
