Yes, I think you are correct. But it feels odd anyway, that some can do great with a diet that excludes one source of biological correct food. Wanted to hear someone elses thoughts…
We are slightly different (not VERY, some are not carnivores and some vegetarian by genotype), we are omnivores and not koalas that eat one thing only, and we are even more different after getting bad health in a number of ways (often people going on different protocols has bad health).
It’s interesting about what happens when mother eats something when we are not born yet, and how we eat early on. When that can change so much, the paleo for all, falls. Sorry, I don’t rememeber what it is called, when genes are “turned on” or not. Some third word, belonging and completing the phenotype and genotype I think ^_^ (I am not Enlish speaking.)
