In a brief Atlantic article about the paleo diet, Alesh Houdek writes:
There is no question that we should eat more fresh and unprocessed foods. . . . The Paleo diet’s dictum to eat as fresh as possible is shared universally with all modern sane eating guidelines.
As regular readers of this blog know, I disagree that “fresh is better”. Fermented is not just better but necessary. To work best, I think our bodies need substantial daily doses of fermented food or their microbial equivalent. Evolution has shaped us to like sour, umami-flavored, and complex-flavored food so that we will eat more microbe-laden food. More about this in these posts. Pass the umeboshi.
