We live in an era of health hype and nutrition propaganda, and we’re suffering for it. Decades of avoiding egg yolks, choosing margarine over butter, and replacing the real foods of our ancestors with low-fat, processed, packaged substitutes have left us with an obesity epidemic, ever-rising rates of chronic disease, and, above all, total confusion about what to eat and why. This is a tragedy of misinformation, food industry shenanigans, and cheap calories disguised as health food. It turns out that everything we’ve been told about how to eat is wrong.
