Prevention of food aversions in cancer patients during treatment
1994
Mattes, R.D.
Food aversions are a common complication of cancer treatment. This study evaluated an approach for blocking the formation of aversions to dietary items in 209 cancer patients treated with chemo- and/or radiotherapy. Patients were exposed to a sensory stimulus (fruit beverage, halava, odor) before initial treatments to provide a target for aversion formation, thereby sparing dietary items. Patients who developed an aversion to the "scapegoat" stimulus experienced a statistically significant 30% reduction in dietary aversion formation relative to patients without a scapegoat aversion or those not exposed to the scapegoat. The most effective scapegoat was the beverage, probably because it was consumed in greatest quantity. Exposure of patients to a "scapegoat" food or beverage just before chemo- and, probably, radiotherapy can markedly reduce the incidence of treatment-related aversions to foods in the patients' customary diet.
