Dr. Jack Goldstein

Does anyone here remember Jack Goldstein of Natural Hygiene? He's dead now, but many years ago (1977) he undertook a long (six weeks) Water Fast, allowing his body to heal Colitis.
I'm tempted to order his book....now long out-of-print....from Amazon.com......WY
P.S. If I remember right, he broke his Fast with Vegetable Broth.
