How else do you plan on tracking 34000’s peoples diet for 12 years? Lock them in a lab?
40 years ago
How else would you measure life expectancy accurately? You you must track people until a statistically significant portion of them die.
and did not check if the Adventist do continue the healthy habits
I don’t really understand how statistically this would matter. They had a large enough study group , tracked them for 12 years and isolated the variables.
each of life expectancy markers yield statistically same result 1.5-2.5 years: not smoking, medium bmi, exercise, eating nuts, being vegetarian.
Yeah and I never claimed it was only cuz of not eating meat.
I am very careful about proclaiming that meat is unhealthy in any dose, because that’s not how humans evolved for the past 300 000 years.
Why do you think natural selection optimizes humans for longevity? (living 85 years free of chronic disease). Evolution just optimizes for survival to reproductive age and successful child bearing.
Just because humans can digest meat and relied on it for survival in harsh conditions does not biologically mean a meat-heavy diet is the optimal fuel for a 90-year lifespan in a modern environment with caloric abundance.

Track local shop data what sales there to double check if people are not lying.

That’s my point - they didn’t repeat the questionaire every x years. They didn’t check if self-reported habits changed. What they in fact measured is “if people in the ~30 have those habits, what is their life expectancy”. Heck, for all we know, at 40 they all became cat eaters or smthing.

That’s how I read your previous comment.

That’s not what I meant. I meant that our digestive system is optimized for (some) meat intake - see e.g. iron and meat effect on iron absorption (from measly 1% non-heme iron to whooping ~15% non-heme iron absorption if meat is present in the dish).

We agree on that, sorry if that wasn’t clear.
