Appeal to nature[0] is a poor mental shortcut. There are tons of natural carcinogens, notably aflatoxins and cycacins. Clothes, refrigeration, and Pasteurization are all extremely recent on an evolutionary timescale. They're all artificial and extremely beneficial to human well-being. Also, the idea that something is good because we've evolved with it gets the mechanism of evolution backward. Even if it were true that evolution's stochastic gradient descent had found the global maximum 15k years ago (instead of perhaps approximating a local maximum), that would imply no changes to the human would improve human reproductive success. It would not imply that no changes to the environment (such as available foods) would improve human reproductive success.
