Get a grip. Your body runs on glucose. Your body has the ability to convert any carbohydrate to glucose (glycolysis) or even to convert proteins and fats to glucose (gluconeogenesis). Glucose is not "poison" in any sense of the word. It is the simplest of carbohydrates and thus a source of rapidly available energy that is also easy to store in the form of glycogen. As with pretty much everything, when you consume glucose in excess or in place of other important nutrients your health can suffer. As far as glucose vs. fructose, sucrose, dextrose etc. outside of minor variances in glycemic index, sugar is sugar is sugar. There is no health benefit or detriment in picking one or the other. Do you know the difference between the much maligned high fructose corn syrup and "real" crystaline table sugar (which BTW isn't any more "natural" than HFCS)? A 10-15% shift in the proportion of sucrose and fructose. "Real" sugar is not pure sucrose and HFCS is not pure fructose, both forms contain fructose, sucrose and glucose/dextrose just in different proportions and not as different as many people would suspect.
Portion and balance throughout a well thought out nutrition plan are the keys, not villanizing one form of sugar over another.
Geez, get yourself a Hershey bar, read a good biochemistry and human nutrition text, and rent a copy of "Attack of the Killer Tomatoes", preferably the version narrated by Elvira. You'll feel better tomorrow.
