University of Sydney study links fruit intake to lower teen depression risk

A three-year study conducted by researchers from the University of Sydney has found a significant link between adolescent dietary habits and mental health. Following 6,537 students across 71 schools in New South Wales, Queensland, and Western Australia, the research published in ‘Child and Adolescent Mental Health’ suggests that fruit consumption may serve as a protective factor against psychological distress.

For every additional 150-gram serving of fruit consumed daily, researchers observed a 13% reduction in the risk of depressive symptoms and a 7% reduction in anxiety risks. Conversely, the regular consumption of sugar-sweetened beverages—including soft drinks, energy drinks, and sports drinks—was associated with an increased likelihood of experiencing both depression and anxiety.

The study tracked participants starting at age 12 to 13, using validated symptom scales to monitor mental well-being. While vegetable consumption did not show a statistically significant correlation with reduced anxiety or depression in this specific study, researchers noted that the protective benefits of fruit may be linked to specific antioxidants and flavonoids.
