Paleolithic diet adopts primal, evolutionary health approach

"If it tastes good, spit it out," was how Jack LaLanne, the so-called "godfather of fitness," put it. This maxim for healthy living has now permeated our culture as indisputable truth. Bacon, doughnuts, chocolate and butter will all kill you. Broccoli, beets and cabbage are what we should be eating instead. Setting aside any deeper reasoning for a moment, we know these to be facts, because we feel it in our gut. Because good can only come from doing things we don't enjoy.This belief makes it easy to believe being a vegetarian or jogging grueling distances every day just has to be healthy. Anyone arguing the contrary fights a brutal uphill battle. Scientists seem to change their minds weekly regarding the healthiness of eggs, but we remain dutifully skeptical of anything that tells us we can eat or do things we enjoy and still be healthy.
