Somehow I remain skeptical that the dairy (and meat) that humans have been eating for literally tens of thousands of years is causing depression and widespread health concerns. I think it's a wee bit more likely that when you're morbidly obese with diabetes, like in that study, and you feel better after eating a controlled, healthy, low-calorie diet, it can be attributed to factors more relevant than veganism.

They literally haven't eaten meat, dairy and eggs 3-5x per day. This is a new phenomenon in the last half-century. And to go back even further, our biochemistry is millions of years old, and is frugivorous in nature. We have no physical adaptations to eating meat. We only started doing it recently as a means of survival when humans left their tropical niche.

Plant-based foods are naturally low in fat, which is calorie dense, so such a diet is in fact ideal for weight loss.

How curious that we are so perfectly able to digest it and thrive from it! I wonder why so many other herbivores didn't get so lucky.

Yes, of course a low calorie diet is ideal for weight loss. What does this have to do with cows milk yogurt? Are you an obese diabetic? If not, I don't see the relevance between your links and the avoidance of milk.

Humans can also eat and digest shirts, pencils and small pieces of plastic. And you didn't provide any evidence of any adaptations we have to meat eating. Check and mate.

We can't derive nutrition from wood or plastic. We derive excellent nutrition from meat, because we have the requisite enzymes. That is the adaptation.
