Sensory perceptions of survivors of cancer and their caregivers upon blinded evaluation of produce from two different sources.

PURPOSE

Evidence documents the role of modifiable lifestyle behaviors in optimizing physical and mental health outcomes for survivors of cancer. Fruit and vegetable consumption is one such behavior, and understanding survivor sensory perceptions of produce can inform interventions aimed at improving dietary patterns. The objective of this study was to assess the sensory perceptions of survivors of cancer and their caregivers when asked to evaluate garden-harvested and grocery-purchased produce.

METHODS

Participants enrolled in a garden-based biobehavioral intervention and their caregivers (n=32) were invited to participate in a sensory evaluation of four produce types: tangerine cherry tomatoes, green cabbage, green beans, and green bell peppers. Samples were coded and distributed in a random fashion, and participants completed validated sensory surveys (preference, liking/acceptability, and discrimination) for each type of produce.

RESULTS

Upon initial blinded evaluation, a significant preference for grocery-purchased produce was noted for green cabbage, green beans, and green bell peppers but not tomatoes (all p<0.05). After self-labeling, however, participants reported a preference for perceived garden-harvested produce (all p≤0.001) even when incorrectly labeled. Liking/acceptability scores were significantly higher among self-labeled garden-harvested versus self-labeled grocery-purchased for all types of produce (all p≤0.001). These data reveal survivors of cancer and their caregivers perceive garden-harvested produce as superior to grocery-purchased, though were unable to accurately identify the two sources based upon sensory factors such as taste, smell, and texture alone when blinded for three of the four types of produce.

CONCLUSION

Findings indicate future interventions should address perceptions of produce to facilitate improvements in consumption in these vulnerable individuals.
