Higher consumption of fruits and vegetables is associated with a reduction in depressive symptoms over time, according to a recent twin study. The study involved approximately 3,480 twins aged 45 and older from the United States, Australia, Denmark, and Sweden. Participants with high fruit and vegetable intake had a lower risk of developing signs of depression compared to those with the lowest intake. The researchers suggest that the beneficial relationship is likely due to the high levels of dietary fibers, vitamins, and micronutrients in fruits and vegetables. While the study does not demonstrate a direct cause-and-effect relationship, lifestyle changes, particularly in diet, could play a role in the prevention of depression.
