I find this line of reasoning disingenuous. After all, we couldn't consume milk hundreds of thousands of years ago. Does your evolutionary heritage put you in places where hundreds of thousand of years ago you would have consumed lemons, coffee, and maple syrup? Is half-and-half natural? Is coffee? Is maple syrup? On a scale of hundreds of thousands of years all those are relatively recent.

It's a bit of straw-man, but I'm try to point out that we can't appeal to being in alignment with our evolution when even those barebone items have been refined and we wouldn't have eaten them in our prehistory.
