" Translated into English for the first time, this book has taken Japan by storm. Dr. Shinya, the world’s leading gastroenterologist, has spent his life researching human digestion. Grounded in his 45 years of medical practice in the U.S. and Japan, his research suggests a miracle enzyme out of which all enzymes the body needs are produced. Diseases occur when this key enzyme is depleted. Dr. Shinya’s science is clearly explained and his revolutionary recommendations for diet and lifestyle are simple and easy to follow. 160 pp."
