Not a week passes without reminders of the health benefits of fruits and vegetables—and recent research suggests aiming for 10 servings daily may be even better than the standard five. A landmark Australian study published in the BMJ medical journal examined vegetable intake's impact on stress, delivering clear results: vegetables help lower stress levels, while fruits alone show no significant effect.
Researchers from the University of Sydney analyzed data from over 60,000 adults aged 45 and older, using the validated Kessler Psychological Distress Scale alongside daily fruit and vegetable consumption records. Participants eating 3 to 4 servings of vegetables daily experienced a 12% reduction in stress compared to those consuming none or just one. This effect was even stronger in women, reaching 18%. Consuming more than 4 servings offered no additional benefits. Green leafy vegetables proved most effective, particularly spinach, which is rich in folate (vitamin B9) and supports production of mood-stabilizing serotonin and dopamine.
While these findings require further validation, particularly on optimal quantities, the evidence reinforces vegetables' broad health advantages. Incorporating more into your diet is a simple, evidence-backed step toward better well-being.
