The findings, published in the journal PLOS One suggest that fruits and vegetables don't only give beneficial effects to the physical body, but as well to psychological health. Increasing the consumption of greens may even improve mental well-being in as short as 2 weeks.
Because studies in recent years indicate that consuming fruit and vegetable may improve mental wellness, lead researcher, Dr. Tamlin Conner, of the Department of Psychology at the University of Otago in New Zealand, and his colleagues, ought to expand a paper, backing up the speculations.

For the study, researchers gathered 171 students aged between 18 and 25, who were divided into three groups for 2 weeks.
The first group continued with their normal eating pattern, the second was personally handed two additional servings of fresh fruits and vegetables (including carrots, kiwi fruit, apples, and oranges) each day, and the last group was given prepaid produce vouchers and received text reminders to consume more fruits and vegetables.
As part of the research, the participants were subjected to assessments that evaluated mood, vitality, motivation, symptoms of depression and anxiety, and other determinants of psychological health.
The results showed, the participants who personally received extra fruits and vegetables consumed the most of these products over the 2 weeks, at 3.7 servings daily, had improved psychological well-being. People in this group had boosted vitality, motivation, with enhanced flourishing.
The other groups had no improvements in mental wellness over the 2 weeks. However, researchers said, there were no improvement in symptoms of depression and anxiety in any of the participants.
"Providing young adults with high-quality FV [fruits and vegetables], not texting them reminders to eat more FV and giving them a voucher, resulted in improvements to their psychological well-being over a 2-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. The findings provide initial validation of a causal relationship between FV and well-being, suggesting that large-scale intervention studies are warranted," according to the study.
