The Gerson Method claims that a strict diet of raw, organic, low-sugar, low-sodium vegetarian food can prevent and cure illnesses, including cancer and depression, which many view as exaggerated and unsupported by scientific evidence. Critics argue that while improved nutrition can enhance health, the claims of curing diseases solely through diet are unfounded and potentially harmful, as seen in past patient outcomes linked to Gerson therapy. The documentary promoting this method has been described as quackery, with concerns about the lack of proper medical training in nutrition among doctors. Historical assessments by reputable medical organizations have consistently found no clinical benefit from Gerson's treatments. Overall, while dietary improvements are beneficial, they should not replace conventional medical care.
