Have you ever tried the carnivore diet for a 30-day period? I've heard many accounts of people trying different sorts of diets based on blood type, but they found that when they just stuck out carnivore (or the lion diet: beef salt & water), once their gut microbiome adjusted, then ended up feeling the best on that. In general, I believe all humans are MUCH more alike than different biologically; we have a few differences in genetic predisposition here and there, but it's insignificant.

And yes, it's insane how much influence religious institutions have had on diet in general! My personal favorite is the Seventh-Day Adventist Church, they were quite...colorful with their methods! 👇
