When I was growing up, if a JW was diagnosed with cancer (or a non-JW family member) they would start eating grapes. Being a JW born in the 50's, I had never read anything in the publications on this (or the danger of aluminum--another story), so asked where they had read it. If anyone has the Golden Age or a scan of the endorsement by Fred Franz, that would be nice.

2. The Grape Cure
The Grape Cure was a book and medical plan endorsed by the Watchtower Society. Dr. Roland Jones was one of Rutherford's doctors who endorsed the Grape Cure. Several others of the board of directors (now called the governing body) endorsed the book and cure including Fred Franz who endorsed it in writing.
According to Roy Goodrich in his Demonism and the Watchtower booklet, "the book has the earmarks of demonism all over it and through it."[17] In a tract on the subject he said the book endorsed astrology and other occult practices and ideas. The author, Joanna Brandt, claimed to have become "super-conscious" and had "unerring 'hunches'" and came in touch with her "subliminal self". The book was therefore a result of "divine illumination" she said.
The Society's endorsement of this book can be explained by their belief in medical radiesthesia. The book promoted the idea that the grape was "magnetic" and "pep[ed] up your mind" as is was "charged with the magnetism of the Sun." The "vibrations of the Sun" are contained in the grape and eating grapes allows you to obtain these "vibrations" in concentrated form, while meat-eaters only get "animal vibrations" from the animals they eat!

The Grape Cure by Johanna Brandt is still around today in the non-JW world and has been passed on by JWs in the 1920's and 30's to JWs today, many their children and grandchildren.
