Lion diets haven't changed since lions became a distinct species. Human diets have changed drastically in the last 10k years. And there are well known examples of humans evolving adaptations to changing diets (lactase persistence in Northern Europeans being the most obvious). It would be crazy to think that other, less obvious adaptations to diet haven't occurred in basically every other region with a distinct diet.
Also look at osteoporosis rates in Western cultures. Lactose tolerance\intolerance is the term. I can smoke 20 cigarettes a day and my body tolerates that. Does not mean it is good for me.
And I’m not sure what you thought I said, but I’m not arguing that milk consumption is great. Well, not in the post you responded to; I do think milk is pretty amazing. All I was saying is that it is an example of humans evolving adaptations to their diets.
But on the topic of milk consumption: there may be drawbacks, but the gene for lactase persistence is one of the fastest spreading genes in recent history. Consuming milk was an utter (there’s a pun to be made here, but I will exercise restraint) game changer for Northern Europeans. Even today, milk is an amazing source of well-balanced nutrition. It’s cheap, easy to consume, and pretty tasty at room temperature.
If it doesn’t cause explosive things to happen to your intestines, that is.
My point is that body will adapt to all situations. Smoke your first cigarette and body revolts. It becomes progressively easy. Body adapted. Is it good?
