Can you point to a specific scientific study that proves that hypothesis?
Not at the moment, no. To be fair, you havn't either.
A vegan diet has an uber-healthy image, and I ask how you know that to be accurate.
Our body may easily adapt to changing lifestyles. After humans started keeping cattle a lactose gene mutated allowing adults to digest dairy products.
This is true. We can, and do, given enough time/generations, adapt to new kinds of food.
However, we cannot "think" or "will" ourselves to adapt. My interest is what is the optimal diet for
modern "model" of human, because that's the only "model" I can work with. I don't know what that
ideal diet consists of, but I'm not willing to assume that just because something has a "Whole Foods"
aura that it is necessarily better.
After all, lactose intolerant is how nature intended us to be.
Well, nature actually does not "intend" anything. All nature can "do" is create variation in a population and place that
population in an environment. At the dawn of farming/herding, the vast majority of humans we lactose intolerant. (actually,
worldwide today the majority still are) However, those few that DID have a gene that allowed them to process dairy had
a strong advantage over their "rivals", because all of a sudden (metaphorically) a whole new food source became uniquely
available them, with no competition from their lactose intolerant peers.
Hell, nature didn't "intend" for us to cook our food, but that turned out to be a really good idea. (Cooking breaks down food
in a way that much more of it's energy is accessible. Same with fermentation.)
The fact that many humans can live to old age on a Standard American Diet isn't necessarily a recommendation of said diet so much as a testament to the adaptability of the human body.
Agreed. I am not, of course, advocating the "Standard American Diet". (aside from it's effectiveness at dosing us with lovely
warm fuzzy dopamine) Americans, though being genetically diverse, don't live especially long or well, and I assume this has
something to do with diet.
However, this once again does not prove that a vegan diet will be an improvement by default.
The Japanese diet has much to be proud of, and it is obviously not vegan
Dairy... What in fact is the main cause of osteoporosus?
This is a new claim to me, and it strikes me as highly dubious.
Could you provide a reference, preferably from a less than batshit-crazy quack "doctor"?
