I'm sure it's not sugar that is dangerous, but amounts of it consumed. You can kill yourself with plain water if you somehow manage to drink 10 liters of it at once. As for sugar, I realized that almost every food contains it, so there's no point to add raw sugar into food. For example, I stopped drinking tea with sugar a while ago and discovered, that green tea is much better without it. Moreover, all other food that tastes sweet became times more sweeter to me, so I just can't consume, say, many candies anymore because of this effect. Raw sugar dulls your taste of sweet, so I highly recommend to stop consuming it. Even just for the sake of better taste, not health.
