"The quest for an ever-whiter shade of bread, which goes all the way back to the Greeks and Romans, is a parable about the folly of human ingenuity -- about how our species can sometimes be too smart for its own good. After figuring out an ingenious system for transforming an all but nutritionally worthless grass into a wholesome food, humanity pushed on intrepidly until it had figured out a way to make that food all but nutritionally worthless yet gain! Here in miniature, I realized, is the whole checkered history of "food processing." Our species' discovery and development of cooking (in the broadest sense of the word) gave us a handful of ingenious technologies for rendering plants and animals more nutritious and unlocking calories unavailable to other creatures. But there eventually came a moment when, propelled by the logic of human desire and technological progress, we began to overprocess certain foods in such a way as to actually render them detrimental to our health and well-being. What had been a highly adaptive set of techniques that contributed substantially to our success as a species turned into a maladaptive one -- contributing to disease and general ill health and now actually threatening to shorten human lives."
