The epidemiological and clinical data also demonstrate the protective and therapeutic effects afforded against many cancers by a variety of nutrients, individually and in combination. Hence, one of the major questions needed to be addressed by public health professionals is whether to wait for definitive proof or to advise people to take protective dietary action now, based on the strong trends emerging from clinical research, despite their imperfection or lack of finality. Given the complexities of designing and conducting randomised clinical trials for cancer patients using such dietary regimes, it is doubtful whether such research will ever be performed. There is also attention paid to achieving a high potassium, low sodium diet. Infuse the body with highly therapeutic and nutritious dietary nutrients.

An evaluation of case histories of 149 Gerson clinic patients was carried out by physicians at Maudsley and Hammersmith hospitals. The above clinical studies and evaluation in no way constitute definitive proof of the clinical efficacy of the Gerson dietary regime in the treatment of cancer.
