JCI Insight - The human brain produces fructose from glucose
I have a short e-mail correspondence with one of the lead authors of the study.
My hypothesis is that fructose is a nutrient and that the brain does this because it requires fructose for some biological function(s). She seems to agree, tentatively. She also admits this is early and many more studies are needed.
This is in stark contrast to the majority of experts I have heard claim that fructose's only potential benefit is to lower the glycemic response to a meal and improve glycogen storage.
I also wonder if some people have mutations in this fructose conversion pathway in the brain. In that case, they would need to consume sucrose in some form to get the fructose the brain needs. This could explain why I feel lousy on a fructose-free diet but feel much better with a small amount of fructose at each meal.
