A daily glass of fruit juice was linked to lower depression scores

A recent study from Newcastle University in the UK suggests that drinking a daily glass of 100% fruit juice or smoothie as part of the 5-a-day fruit and vegetable recommendation may contribute to improved mental well-being. In a randomized controlled trial, researchers observed adults who regularly consumed low amounts of fruits and vegetables, providing support to increase their intake.

Some participants were instructed to meet the 5-a-day goal using only whole fruits and vegetables, while others increased both their intake of whole fruits and vegetables and consumed one glass of fruit juice or a smoothie daily. After four weeks, both groups increased their consumption of fruits and vegetables, with the latter group also reporting lower depression scores.

The study, funded by the Fruit Juice Science Centre, adds to evidence that simple dietary changes can positively impact mental health. Dr. Courtney Neal, who conducted the study while at Newcastle University, stated that while most people know that the 5-a-day recommendation is beneficial for health, many struggle to meet it. The trial demonstrated that targeted financial and educational support can help individuals make meaningful changes to their diet.
