> People do switch to healthier or perceiver-to-be-healthier alternatives once they get sick I always forget this part, and you're right – it's critical, and often used by industry interests to help indicate healthier options are in fact less healthy. It can be hard to catch sometimes, and before I knew how to read these studies, I was tricked by it very, very often. We also know in the case of the disease they're concerned about here, that without radical dietary changes (i.e. eating plant fats OR animal fats won't save you here) then the damages you've likely been exposing yourself to for decades are probably going to kill you soon, anyway. Arterial plaque doesn't vanish when you start frying eggs in canola instead of pork fat. Another thing to consider here is: what do elderly Chinese consider to be healthy? Are the ones switching to animal fats doing that because it's culturally perceived as healthier? Or are they more like North Americans, thinking canola is the heart-healthy oil? It's hard to tell, not being around the age of 65 and living in China. I do appreciate that they accounted for diet composition to a degree, though it's self-reported and again, not reliable particularly among people trying to change old habits.
