Fructose is not harmful at normal physiological levels, but may be dangerous at super-physiological levels achievable through high-fructose corn syrup consumption.

“why i don't think that fructose is harmful within normal physiologic levels as you suggested at super physiologic levels which are easily achievable by consuming high fructose corns here i think it could be possibly dangerous based on the differences between fructolysis and glycolysis or fructolysis and glycolysis which we're going to talk about”
