“A diet rich in readily available nutrients allows the bones to mineralize properly, particularly during gestation and early development, and gives the teeth immunity to decay throughout the stresses of life. Not surprisingly, he found that the native diets that conferred such good health on healthy, so-called primitive groups were rich in minerals, particularly calcium and phosphorus, necessary for healthy bones and teeth. What is surprising about the work of Weston Price is his discovery that these healthy diets always contained a good source of what he called "fat-soluble activators," nutrients like vitamin A and vitamin D, and another vitamin he discovered called Activator X or the Price Factor. These nutrients are found only in certain animal fats. Foods that provided these nutrients were considered sacred by the healthy groups he studied. These foods included liver and other organ meats from grazing animals; fish eggs; fish liver oils; fish and shellfish; and butter from cows eating rapidly growing green grass from well-mineralized pastures. Price concluded that without a rich supply of these fat-soluble nutrients, the body cannot properly use the minerals in food. These fat-soluble nutrients also nourish the glands and organs to give healthy indigenous peoples plenty of immunity during times of stress.”

“What Dr. Price's work teaches us is that the absolute fundamental requirement of healthy diets cannot be found in pasta, nor vegetable juices, nor oat bran, nor olive
oil, but only in certain types of animal fats. These fats come from animals who consume green, growing organisms (such as grass and plankton), or who consume other animals that have consumed green, growing organisms (such as insects). What is tragic is the difficulty in finding such foods today. Most of our dairy cows spend their entire lives in confinement and never see green grass; chickens are kept in pens and fed mostly grains; pigs are raised in factories and never see sunlight; even fish are now raised in fish farms and given inappropriate feed, like soy pellets.
Even worse, most people avoid these foods today because medical spokesmen claim they cause cancer, heart disease or weight gain, even though a number of highly qualified scientists have admirably refuted these charges. Suffice it to say that the patient who is afraid of consuming foods containing animal fats and cholesterol will make no headway in his efforts to improve his diet as these foods are absolutely vital for good health.”
