Longevity scientists are mostly just experts in the field of getting duped by pension fraudsters who say what they want to hear: https://en.wikipedia.org/wiki/Blue_zone#Scientific_reception

Parts of the field are in worryingly deep denial about the number and magnitude of confounding variables a moderate level of skeptical empiricism suggests could be present in their foundational research. As, again, in the specific case that user is worried you're glossing over: The lipid hypothesis was probably developed from studies with diets also high in processed foods, simple carbohydrates, added sugar, salt, and vegetable oils, and low in organ meats and heavy-metal-free fish. Don't we all agree these things as a staple in a diet will probably negative health outcomes on their own? How can the field be confident enough to publicly assert a model on that? Have they put the rice-fruit-and-legume diet through as rigorous a comparison to the chicken-veg-and-liver diet as they did to the McDonald's special diet? It'd be nice to develop a culture of a straight answer of "Yes, and here's the confirming metaanalysis [1]" on this question in place of this "mind-your-seniors" browbeating. Isn't that what science is supposed to be about?

You've cited the debunking of a demographer to try to debunk the work of cardiologists. Okay?

Once again, I, and probably the vast majority of people on HN, aren't properly educated to have a comprehensive view of the medical literature on the matter and properly digest it all. I'm not going to participate in a debate on the merits of guidelines published and signed by thousands of medical and scientific experts from around the world, to even try and assume I could do so with a couple of hours here and there when they're looking into these issues for 8 hours a day for years on end would be arrogant on my part.

If you want to challenge someone who might be able to give you an informed answer, your best bet is to talk to an actual expert on the matter. You can find some people in the articles below.
