All sugar eventually breaks down to glucose; enough of any sugar will cause your blood sugar to rise. None of the sugars is particularly good for a diabetic individual; you're better off eating something that's complex than simple if you don't want to cause a sudden increase in your blood sugar. If you REALLY need to boost your blood sugar quickly. In that case, simple sugars are best, like fructose, contained in orange juice, soft drinks, or honey, among other things.
Honey contains fructose and glucose. In general, fructose is sugar created by plants. They ALL break down to glucose in the human body. Honey would be a good source of fast sugar to the bloodstream if your sugar has dropped too low. Table sugar takes longer to break down; fructose is one of the products of the digestion of sucrose, which is table sugar.
