The notion that we haven't had time to "evolve" to adapt to a modern diet is a bit absurd. Because here we are: eating it and living as much as a century on it. It doesn't take millions of years for natural selection to eliminate genetic lines that can't thrive on a particular diet; the mere thousands in which humans switched from hunter-gatherers into farmers has been enough. That doesn't mean that the rapid biotechnological change of the past century or two hasn't produced a diet that we can all do well on – high fructose corn syrup and factory-raised meat are putting a whole new set of selection criteria on H. sapiens – but the typical diet of the 19th century, with a corresponding level of physical activity, plus some modern medical technology to address illnesses that aren't related to nutrition, is the best prescription for human longevity.
