Drinking a daily glass of 100% fruit juice or a smoothie as part of the UK's 5-a-day guidance may help support mental well-being, according to research from Newcastle University in the UK.
In a randomized controlled trial, adults who typically ate relatively little fruit and vegetables received support to increase their intake. Some participants were also asked to include one glass of fruit juice or a smoothie each day as they worked toward the 5-a-day target.
After four weeks, both groups increased the amount of fruit and vegetables they consumed. However, participants who included fruit juice or a smoothie also reported lower depression scores.
The peer-reviewed findings were published in the British Journal of Nutrition and funded by the Fruit Juice Science Centre. Researchers say the results add to evidence that relatively simple and practical dietary changes may have benefits for mental health.
Dr. Courtney Neal, who completed the study while at Newcastle University and is now at the University of Liverpool, said: "While most people know eating 5-a-day can be good for your health, many people struggle to.
