Prior to 1980, how in the world did anyone know how to eat? When you think of all the centuries, the millennia of human existence, how did the species manage to survive bumbling their way through day after day of undirected eating patterns? I’m guessing those of you who know me expected a few irreverent remarks when you read the title of today’s post. Still, I’ll try to keep myself on a short leash today. It’s a legitimate and even, in some regards, culturally (and probably politically) significant question: why were government dietary guidelines ever put in place—and what was the backstory of their uses and modifications over time? Finally, what perspective can it bring to our understanding of embracing a “niche” dietary model like the Primal Blueprint?
