Weren't you into
the paleo diet? Are you still?
I'm no longer interested in the paleo diet when I found out that I carry the East African lactase persistence gene. I'm a Neolithic mutant so why eat paleo food.
I'm not lactose intolerant either.

But you can still be Primal-Paleo. That includes dairy. Some have issues with the protein casein in cow's milk.
The caano is North America isn't quite the same as what's found in Europe, Asia and Africa.
A protein fragment called BMC-7 is associated with autoimmunity and depending on the type of amino acid it binds to in the bloodstream will reflect what happens. The amino acid proline is found in these Immigrant cows (A2) which holds tightly to BCM-7, while histidine is found in North American cattle (A1 cows). And BCM-7 released from milk in A1 cows in North America is several times higher than their European counterparts.
Doesn't the milk taste different around here?

Also, if an individual improves their gut health they might not be as reactive to BCM-7 in general.
Similarly, I've seen people who were fine with consuming dairy raw, in the form of fermented
cheeses.

I could never go vegan. I don't have the constitution for it. I've tried long ago and even with B12 supplementation, I was still deficient. My theory is Somalis don't fair well totally meatless. We're carnivore leaning ominvores. Whereas, these West Africans do better as vegans. Honestly, we need personalized nutrition informed by one's genetic makeup, where they live and any nutrient interactions that may or might not agree with them (at the individual level).
