Abstract

Introduction: Psychological resilience, the ability to adapt to adversity and maintain emotional well-being, protects against mental health challenges. This study investigates its association with fruit and vegetable intake among U.S. adults using 2023 Behavioral Risk Factor Surveillance System (BRFSS) data. Methods: Daily fruit and vegetable consumption (grams/day) was estimated from frequency responses, assuming 1.5 servings (135 grams) per instance. Resilience was assessed using a composite index based on poor mental health days (_MENTHLTH ≤5 for high resilience) and emotional support (_EMTSUPP 1-2 for high), categorized as high, moderate, or low. Descriptive statistics, t-tests, ANOVA, and chi-square tests were used, with multivariable regressions adjusting for confounders (income, education, smoking). Results: The high-resilience group consumed 420 grams/day (SD=115), compared to 355 grams/day (SD=105) in the low-resilience group (p<0.01, Cohen’s d=0.58). Sixty-seven percent of high-resilience individuals met the WHO ≥400 grams/day recommendation, versus 46% in the low-resilience group (p<0.001). Women and younger adults (18-24 years) in high-resilience groups had higher intakes (p<0.05). Multivariable logistic regression showed higher intake was associated with high resilience (OR=1.45, p<0.01). Conclusion: These findings suggest that nutrient-dense diets may enhance resilience, though longitudinal studies are needed to confirm causality and explore mechanisms like the gut-brain axis.
