For their study, Conner and team enrolled 171 students aged between 18 and 25 for their study, and they were divided into three groups for 2 weeks. One group continued with their normal eating pattern, one was personally handed two additional servings of fresh fruits and vegetables (including carrots, kiwi fruit, apples, and oranges) each day, while the remaining group was given prepaid produce vouchers and received text reminders to consume more fruits and vegetables.

The researchers found that participants who personally received extra fruits and vegetables consumed the most of these products over the 2 weeks, at 3.7 servings daily, and it was this group that experienced improvements in psychological well-being. In particular, these participants demonstrated improvements in vitality, motivation, and flourishing.

CommentsFurthermore, no improvements were seen in symptoms of depression and anxiety in any of the groups. "The majority of research linking depression to dietary patterns has been longitudinal, meaning that possible differences in ill-being may be established over a much longer period of time rather than our brief 2-week period," note the authors.
