Many studies have arrived at the same conclusion, that HFCS is bad for you.
Sucrose, which is cane or beet sugar, is fructose and glucose chemically bonded together. The body takes it and breaks the bond, processes the glucose and fructose up to a point then shuts down the cleaving and no more fructose or glucose enters your system.
HFCS, as noted in the study, bypasses the bodies control mechanism and you get all the problems noted. So with less total input of “sugar” (which is what HFCS is called by the corn industry and many others) you get a magnified impact on your health.
