Historically, the diets of healthy nonindustrialized peoples throughout the world varied according to climate and terrain—but all of them can be described as nutrient-dense and rich in vitamins and minerals.
Weston A. Price, an influential researcher from Cleveland (1870–1948), analyzed some of these foods and found that the diets of “primitive peoples” contained four times more minerals than today’s average American diet. Of note were the high levels of naturally occurring, fat-soluble vitamins found in the food—vitamins A, D, and K2—which Price referred to as “activators.”
