Someone with more domain knowledge, does this study hold water? Even perhaps as a reason to look further into the relationship between diet and Alzheimer’s?
You're always going to have members of the general public and docs who don't keep upon on continuing nutritional education (snark, there isn't any) saying stuff that was out of date decades ago but I'd say the stuff in that video is pretty much mainstream now.
Perhaps I'm reading this wrong but the article suggests that it's not from digested fructose, rather the body is producing fructose. I'm confused.
excess fructose (in particular in ultra-processed forms) causes metabolic derangement but consuming too much of those other 3 esp from ultra processed foods, also activates the "switch" leading to endogenous fructose production and more derangement.
The role of sedentarism in all this is somewhat under-explored though.
