Fructose More Toxic than Table Sugar in Mice

[Trillo]

14. Mildly interesting topic to me, I use invert syrup sometimes

which is sucrose split into fructose and glucose. Anyway, from Wikipedia, "... gastric acidity converts sucrose to glucose and fructose during digestion."

From OP's article

The study found no differences in survival, reproduction or territoriality of male mice on the high-fructose and sucrose diets. The researchers say that may be because both sugars are equally toxic to male mice.

The new study found no differences in males on the two diets in terms of survival, reproduction or ability to compete for territory. But Potts said the 2013 study showed male mice were a quarter less likely to hold territory and reproduce on the fructose-glucose mix compared with starch. That, combined with the new findings, “suggests sucrose is as bad for males as high-fructose corn syrup,” he says.
