That doesn't implicate sugar any more than excess body fat. There is no established causality from sugar intake. It's just popular to slam on sugar and promote fat acceptance so sugar is the "obvious" demon.
Some people also suggest Alzheimer is a 3rd form of diabetes. I read a study that nasal applied insulin actually helps Alzheimer.
So, no slamming of sugar, just some preliminary evidence that may want to ask yourself if you really need to drink a liter or 2 liters of coke per day.
