Grape Diet

The American Cancer Society's own professional-journal review of the Grape Diet, resolved directly via the Crossref API (https://api.crossref.org/works/10.3322/canjclin.24.3.144): title 'Grape Diet', container CA: A Cancer Journal for Clinicians, volume 24, issue 3, pages 144-146, published 1974-05-01, publisher Wiley (the ACS's own clinician-facing journal), ISSN 0007-9235. This is one of the American Cancer Society's repeated evidence reviews of Brandt's Grape Cure (per Quackwatch's bibliography, ACS reviewed the claim in 1965, 1971, 1974, and 2000, each time finding no evidence of benefit). The article body is paywalled (Wiley returned HTTP 403 to automated fetch); cited here by its Crossref-resolved bibliographic metadata only, with no verbatim quote taken from the body text. Authoritative professional-society evidentiary-failure source, directly on point (a dedicated review of this exact marketed claim, not a general cancer-quackery survey).
