“Most of the world is lactose intolerant” yeah because most of the world isn’t white people who lived in parts of the world where there wasn’t as much sun. Hence these people evolved to get extra Vitamin D from dairy products.

Miss me with that anti-milk propaganda.

Milk at the store has lots of Vitamin D because they fortify it, it wasn’t as great of a source while our ancestors were evolving. Which populations developed lactase persistence probably has more to do with whether the land/climate was conducive to keeping herds of grazing animals. If you had livestock handy, then having an extra way to get food from them was beneficial; if you didn’t, you wouldn’t have access to dairy anyway, so no need to keep making the enzyme to digest it.
