"Eating more fruits and veg can boost psychological well-being"

New research finds that increasing fruit and vegetable consumption may improve psychological well-being in as little as two weeks time.

Researcher Dr. Tamlin Conner of the Department of Psychology at the University of Otago in New Zealand found that young adults who were given extra fruits and vegetables each day for 14 days experienced a boost in motivation and vitality.

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 in recent years, studies have suggested that fruit and vegetable intake may improve mental health, researchers enrolled 171 students aged between 18 and 25 to their study, dividing them into three groups for 2 weeks.

At the beginning and end of the study, 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.

According to an article by, 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 this group experienced great improvements in psychological well-being. In particular, these participants demonstrated improvements in vitality, motivation, and flourishing.
