Refined sugar, in fact any sugar that is not natural like fruits, and in excess these are not good either. I like salty food more... much more, plus I'm a low blood pressure person. But sweets don't appeal to me, I eat a little bit and I find it so cloying that I can't eat any more hahaha.

I almost don't eat things with sugar, although flours also contain it... it's very difficult to give it up completely, but as I'm not so fond of them, I'm fine. You have to learn to control yourself and it's complicated.
