A mountain people renowned for their longevity and vigor, the Hunza of the Himalayas commonly live to be 100 or older, and cancer and degenerative disease are virtually unknown in their communities. G. T. Wrench, an English physician, searched for the wellspring of the Hunzas' fitness and health in the 1930's. He found the answers in the work of Dr. Robert McCarrison who had been Director of Nutrition Research in India, and who studies the Hunza people for many years. Their diet and their methods of food cultivation and soil preparation are the key as detailed in this timeless book, a lost classic newly returned to print.
