Background: Strong evidence exists for the beneficial impact of modifiable lifestyle behaviors, including diet, on healthy cancer survivorship. In 2013, focus groups were conducted at the Garden of Hope to explore perceptions of behavioral changes in cancer survivors participating in an urban-gardening intervention. One theme that emerged was concern for sustainability of improved produce consumption beyond the harvesting season. Objective: The purpose of this study was to determine sensory perceptions of cancer survivors comparing garden-harvested versus grocery-purchased produce. Methods: Sensory evaluation was employed to assess participants (N=34) responses to 4 produce samples: tomatoes, green beans, green bell peppers, and cabbage. Each sample (4 garden-harvested and 4 grocery-purchased) were prepared to minimize bias and placed into cups with randomized 3-digit codes. Participants then completed a series of sensory surveys (preference, acceptability, and discrimination). Results: A significant preference for grocery-produce was noted with beans, peppers, and cabbage when evaluated blind (p<0.001, p=0.007, p=0.007, respectively). Participants were only able to correctly label the tomatoes as either garden or grocery (p<0.002). After self-labeling (SL), participants significantly preferred SL garden groups for all vegetables (p<0.001) even if they were in fact the grocery-varieties. Analysis of variance for the SL groups showed a significant difference in the acceptability of SL garden versus SL grocery for all vegetables (cabbage and peppers p<0.001; tomato and beans p=0.001). Conclusions: Sensory analysis can provide valuable feedback to measure sensory perceptions of produce grown in different environments. These results indicate that individuals perceive garden-grown produce as a better option than store-bought produce even though they are typically unable to distinguish a significant sensory difference or correctly label the produce when blinded. These results aid in targeting initiatives to better address sustainability concerns of lifestyle interventions embracing urban gardening.
