Fruits, Vegetables Pivotal for Mental Health

Fruits and vegetables are a pivotal part of a healthful diet, but their benefits are not limited to physical health. New research finds that increasing fruit and vegetable consumption may improve psychological well-being in as little as 2 weeks. 
Study leader Dr. Tamlin Conner of the Department of Psychology at the University of Otago in New Zealand, and colleagues found that young adults who were given extra fruits and vegetables each day for 14 days ate more of the produce and experienced a boost in motivation and vitality.
The researchers recently reported their findings in the journal PLOS One.
According to the United States Department of Agriculture, adults should aim to consume around two cups of fruits and around two to three cups of vegetables daily.
One cup of fruits is the equivalent to half a grapefruit or a large orange, and one cup of vegetables is proportionate to one large red pepper or a large, baked sweet potato.
As part of a healthful diet, fruits and vegetables can help reduce the risk of obesity, type 2 diabetes, heart disease, stroke, and some types of cancer.
In recent years, studies have suggested that fruit and vegetable intake may also improve mental health, medicalnewstoday.com reported.
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.
Participants were subjected to psychological assessments that evaluated mood, vitality, motivation, symptoms of depression and anxiety, and other determinants of mental health and well-being.

  Improvements Seen
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.
The other two groups showed no improvements in psychological wellbeing over the 2-week period.
Furthermore, 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.
Still, researchers say that their findings indicate that increasing the intake of fruits and vegetables through personal delivery may lead to rapid benefits for psychological wellbeing.
This is the first study to show that providing high-quality fruits and vegetables to young adults can result in short-term improvements in vitality, flourishing, and motivation.
