Very interesting and inline with what the manufacturers have been pushing lately. But I didn't dig far enough to find the original research and whether/to what extent it was funded or driven by the corn producers and HFCS manufacturers. Personally I just can't tolerate much fructose of any kind (natural or refined) on a long run, but that's just me.
