The SCD® Knowledge Base is a long-time resource of information on all aspects of the Specific Carbohydrate Diet®. Much of the information has been gathered from the original Long Island List Serve and other SCD mailing lists. The authors are credited if known. The Knowledge Base was originally on the official Breaking the Vicious Cycle website, but has been moved here with the guidance and input of Judy Harod, Elaine Gotschall's daughter and holder of the SCD copyright. Entries are screen grabs from the former site, so links are not live.
