First of all it’s a nice study. The dosages they always give are way too high and mice are rarely a reliable model. But you’re also ignoring the fact that the same study shows that glucose inhibits the behavior. So your claim that the study indicates its sugar is incorrect. The study indicates a possible impact from fructose which is countered by glucose, so the real issue is the fructose to glucose ratio. Table sugar providing equal fructose and glucose molecules is acquitted by this study.
