Guys... Alzheimer's is 60-80% heritable, and driven largely by APOE genotype. No, you cannot get out of it with One Quick Trick. We have to find therapeutics to make real progress here.

This kind of misdirection is not helpful to the research community, or encouraging politicians to fund effective projects. Everyone WANTS a quick lifestyle change and will latch onto these things, but this is a real biological disease that needs real molecular fixes. Sorry, it's just how it is.
