Pros and Cons of Dietary Strategies Popular Among Cancer Patients
As
many as 48% of cancer patients pursue popular diets, including the
alkaline, Paleolithic, ketogenic, vegan, and macrobiotic diets, with the
hope that they will improve survival and prevent recurrence. These
diets have positive aspects consistent with the dietary guidelines
proposed by the American Cancer Society (ACS) and the American Institute
for Cancer Research (AICR). All of the diets emphasize eating
vegetables, all but the ketogenic diet encourage eating fruit, and all
but the vegan diet limit refined grains and alcohol. Both the
macrobiotic and the alkaline diets meet the majority of the ACS and AICR
guidelines. Negative aspects of these diets include pseudo-scientific
rationales for their anti-cancer properties, limited evidence that they
improve cancer outcomes, the possibility for nutrient insufficiencies,
and elimination of food groups proven beneficial for cancer prevention
and general health. Moreover, with nutritional counseling, nutrient
insufficiencies and misalignment with cancer clinical guidelines can
often be addressed. Clinicians should consider strategies to encourage
evidence-based dietary changes that encourage positive features of
popular cancer diets, while minimizing negative aspects.
