Didn’t Hakim say that it was a causation v correlation problem?
Vegans generally tend to already be more concerned about their health, along with generally skewing towards the wealthy side, so it’s hard to determine what, if anything the veganism is doing in the equation.
Yes, I know he said that. The meme says “correlated.” The thing I always like to point out is it’s cheaper to have a healthy diet without/with minimal animal products than to have a healthy omnivorous diet.
