So, you claim that pure glucose has no known health problems associated with it? (If I understand correctly this is an equivalent claim to what you say, since the other 50% is glucose).
A random google search (e.g. see http://www.lef.org/magazine/mag2011/jan2011_Glucose-The-Sile... ) indicates that this belief is not part of the consensus. Care to back that up?
Table sugar consumption is indeed bad for you only because of its 50% of fructose.
