…Eating a diet that contains high fructose corn syrup (HFCS) equivalent to the added sugar we can have in our diet is bad news for fertility and life expectancy, in female mice at least.
Researchers from the University of Utah fed mice a diet containing either HFCS or table sugar, both of which are made up of a mixture of fructose and glucose. The difference is that in table sugar they are chemically bound (and so in equal amounts) and in HFCS they are free molecules.
They found that female mice fed the HFCS produced 26.4 percent fewer offspring and had death rates 1.87 times higher than those on the sucrose diet. There were no differences for the males but before you get too excited the authors cite an earlier paper from them that showed that sucrose is also detrimental for male mice.
They therefore hypothesise that sucrose and HFCS are equally toxic for male mice.
