Growing Minds: Evaluating the Relationship between Gardening and Fruit and Vegetable Consumption in Older Adults

Abstract

New dietary guidelines recommend eating more than five servings of fruit and vegetables each day without setting upper limitations. Although older adults tend to report a higher intake of fruit and vegetables than other age groups, over half of the U.S. older population does not meet the recommendation of five daily servings of fruit and vegetables. Research has shown that gardening is one way of improving fruit and vegetable intake. The primary focuses of this study were to examine and compare fruit and vegetable consumption of gardeners and nongardeners and to investigate any differences in fruit and vegetable consumption of long-term gardeners when compared with newer gardeners in adults older than age 50 years. An online survey was designed to be answered by older adults (50 years or older) and respondents self-selected themselves for inclusion in the study. A total of 261 questionnaires was completed. Data collected were analyzed using statistical procedures, including descriptive statistics, Pearson's product-moment correlations, and multivariate analysis of variance. The results of this research supports previous studies that indicated gardeners were more likely to consume vegetables when compared with nongardeners. However, these results were not found with regard to fruit consumption between gardeners and nongardeners. Additionally, the length of time an individual reported having participated in gardening activities seemed to have no relationship to the number of vegetables and fruit reported as consumed, which suggests gardening intervention programs late in life would be an effective method of boosting vegetable and fruit consumption in older adults. Gender was also evaluated with no statistically significant differences found for overall fruit and vegetable intake.
