By Dr. Weston A. Price
Summary: The notion of “alkalizing” one’s diet—or eating foods that supposedly increase the pH within the body and thus optimize health—has been around as long as the science of nutrition itself. In this 1935 article, famed dentist and nutrition pioneer Dr. Weston A. Price debunks the hypothesis that an alkalizing diet helps prevent tooth decay. Citing data from his famous worldwide study of populations free of dental disease and other degenerative illness, Dr. Price states, “In no instance have I found the change from a high immunity to dental caries [cavities] to a high susceptibility…to be associated with a change from a diet with a high potential alkalinity to a high potential acidity.” In fact, he adds, his data show, if anything, that good tooth health is the result of an acidifying diet. Dr. Price further discounts the notion that an alkalizing diet promotes health in general and instead stresses the importance of eating whole foods rich in vitamins and minerals, particularly the fat-soluble vitamins so abundant in animal foods.
