The Weston A. Price Foundation

When Dr. price analyzed the foods used by isolated peoples he found that, in comparison to the American diet of his day, they provided at least four times the water- soluble vitamins, calcium and other minerals, and at least TEN times the fat-soluble vitamins, from animal foods such as butter, fish eggs, shellfish, organ meats, eggs and animal fats—the very cholesterol-rich foods now shunned by the American public as unhealthful. These healthy traditional peoples knew instinctively what scientists of Dr. price’s day had recently discovered—that these fat-soluble vitamins, vitamins A and D, were vital to health because they acted as catalysts to mineral absorption and protein utilization. Without them, we cannot absorb minerals, no matter how abundant they may be in our food. Dr. price discovered an additional fat-soluble nutrient, which he labeled Activator X, that is present in fish livers and shellfish, and organ meats and butter from cows eating rapidly growing green grass in the spring and fall. All primitive groups had a source of Activator X, now thought to be vitamin K2, in their diets.
