I think the studies are early and wrapped up in a lot of same nonsense that infects pretty much anything that touches food.
From my second link:
For example a diet high in saturated fat is linked with Alzheimer’s risk, but that may be because junk food is typically high in saturated fat. Would we still see the link in whole foods naturally high in saturated fat, like meat or dairy?
Additionally, specific nutrients (such as antioxidants or omega-3 fats) may not reduce Alzheimer’s risk when consumed individually. That is, nutrients may need to be eaten as part of whole foods to have an effect, known as food synergy.
As we know Sat Fat is frequently code for a person’s crap diet, it could be that Apoe4 users would process sat fat fine if they cut the sugar, flour, corn, and junky transfats from their diets. I suspect I have an Apoe4, as there’s Alz on both sides of my family, and a strong line on my dad’s side. But there’s also a lot of diabetes on that side, which is an independent risk for Alz. If you see a lot of diabetes, you have to wonder if, evolutionarily speaking, there was an advantage that has since been corrupted by high carb diets. Like maybe you make more beta-amyloid with sat fat and Apoe4, but without the carbs, you can clear that crap out of your brain by delivering the proper antioxidants and other cleaning apparatus. Or maybe you get better with regular deep, Gamma sleep and our dumb modern world screws that up for you.
