Adequate consumption of fruits and vegetables (F&V) as part of a healthy diet may help decrease the odds of suffering from chronic diseases, however, most Western populations fail to achieve dietary recommendations, particularly at lower income levels. Efforts need to be directed to establish cost-effective and practical methods to tackle the environmental and personal factors related to F&V consumption. In this study by Gans et al. (2018), the authors bring forth the results of a cluster randomized controlled trial investigating the 'Live Well, Viva Bien' (LWVB), a multifaceted intervention that combines discounted, mobile, fresh F&V markets and nutritional education. The LWVB intervention targeted 15 subsidized housing locations (8 intervention [n = 837] and 7 control locations [n = 760], 54% Hispanic, 73% women, 17% black, mean age = 54 years), presenting them with either mobile F&V markets plus nutrition education (through campaigns, newsletters, DVDs, recipes and chef demonstrations) at intervention locations, or with physical activity and stress interventions at the control locations. F&V consumption was evaluated using the National Cancer Institute's 'Eating at America's Table All Day Screener', and study participants were followed up at 6 and 12 months. Analysis of the results revealed a significant increase of F&V consumption and F&V-related dietary behaviors in the intervention group, and a concomitant decrease of F&V consumption in the control group. In addition, participants who attended more F&V markets reported a significantly higher likelihood to consume more F&V, and that the nutrition education components (namely DVDs, recipes, and taste-testing) led to enhancing F&V consumption. In conclusion, the authors comment on how the LWVB intervention showcased the impact of year-round F&V markets on dietary intake in low-income adults, and hence the importance of mobile F&V markets. Furthermore, the results provide evidence to aid environmental change initiatives and help ameliorate F&V consumption and dietary-related health disparities.
