In the United States
Gerson emigrated to the United States in 1936, passed his medical board examination, and became a U.S. citizen in 1942.[ The rest of his family died at the hands of the Nazis. In the U.S., Gerson applied his dietary therapy to several cancer patients, claiming good results, but other workers found his methodology and claims unconvincing.

headed by the medical establishment prevented Gerson from publishing proof that his therapy worked. In 1958, Gerson published a book in which he claimed to have cured 50 terminal cancer patients: ''A Cancer Therapy: Results of 50 Cases''. In 1953, Gerson's malpractice insurance was discontinued and, in 1958, his medical license in New York was suspended for two years.[

Death
Gerson died March 8, 1959 of pneumonia. A conspiracy theory has subsequently spread that Gerson was murdered following a lifetime of supposed persecution.

found that the institute's claims of cure were based not on actual documentation of survival, but on "a combination of the doctor's estimate that the departing patient has a 'reasonable chance of surviving', plus feelings that the Institute staff have about the status of people who call in".
A 1994 article in the ''Journal of Naturopathic Medicine'' attempted to follow 39 Gerson patients in Tijuana. Patient interviews were used to confirm the existence and stage of cancer; most patients were unaware of the stage of their tumor, and medical records were not available. Most patients were lost to follow-up; of the patients successfully followed, 10 died and six were alive at their last follow-up. Review of this study pointed out its "obvious flaws", including "the majority of patients lost to follow-up, lack of access to detailed medical records, and reliance upon patients for disease stage information"; the authors themselves regarded the results as unclear.

The therapy may be especially hazardous to pregnant or breast-feeding women.][
Coffee enemas have contributed to the deaths of at least three people in the United States. Coffee enemas "can cause colitis (inflammation of the bowel), fluid and electrolyte imbalances, and in some cases septicemia".] The recommended diet may not be nutritionally adequate. The diet has been blamed for the deaths of patients who substituted it for standard medical care.
Relying on the therapy alone while avoiding or delaying conventional medical care for cancer has serious health consequences.[ Jessica Ainscough, better known as "The Wellness Warrior", was a major proponent of the Gerson diet after her diagnosis with cancer. She rejected medical treatment and followed the diet strictly, documenting her progress in a popular blog. She died from her untreated cancer in February 2015, aged 29.]
