If between fats and sugars, one is "bad" and the other is not, then any increase in the one that is bad will have negative effects regardless of how much the non-bad one is increased. Nutrition and human biology is obviously more complicated than just this, but I'm just pointing out that data like this provides as much evidence for Jason's argument as it does for your argument.
