Can you clarify what you mean? I might have misunderstood you. I was a little flabberghasted that you seemed to say that there's no causality between sugar and insulin resistance. Based on everything I've been reading in the past 10 years, there's very clear causality between insulinogenic foods, insulin resistance, and body fat. The mechanisms, I thought, were also very well understood.

Perhaps they're talking about Alzheimers specifically? If you frame Alzheimers as a disease of affluence (Which is a bit of a stretch, I'll admit), you could look to the same causes (like excess added sugar in industrialized diets)

There is a link between sugar intake and diabetes.

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.
