The physical health benefits of fruit and vegetables are well established. People who eat more fruit and vegetables have better cardiovascular health, reduced risk of some cancers, and greater longevity than people who eat fewer FV . There is also growing evidence that people who eat more FV have better mental health. Higher consumption of FV is correlated with several psychological outcomes including a lower incidence of depression and anxiety greater happiness higher life satisfaction, and greater social-emotional well-being or “flourishing”.
This study tested the psychological benefits of a 14-day preregistered clinical intervention to increase fruit and vegetable (FV) consumption in 171 low-FV-consuming young adults (67% female, aged 18–25).
And surprisingly, the result of providing young adults with high-quality FV rendered improvements to their psychological well-being over just two week period. This is the first study to show that providing high-quality FV to young adults can result in short-term improvements in vitality, flourishing, and motivation.
