This is a classic study and commentary on the relationship between traditional nature-based diet and health. Traveling throughout the world, primarily in the 1930s, Dr. and Mrs. Price investigated cultures that had not yet been exposed to the “foods of commerce”. It quickly became apparent to him that “modern ills” were a result of “modern food”. The fascinating accounts and accompanying photos provide compelling reasons for the return by today’s health-conscious individual to a “primitive diet”. Dr. Price’s study gave us the first insight into the calcium-phosphorus ratio, and leaves us with the question of why with all our modern technology do 5 out of 10 suffer from heart disease, and 4 out of 10 contract cancer.
