Why fruits and vegetables are critical to reducing depression

Researchers in Iran recently published a study in The British Journal of Nutrition, showing a connection between fruit and vegetable consumption and depression risk.

The researchers systematically reviewed the data from nearly 30 studies previously conducted on the relationship between depression risk and the eating of fruits and vegetables.

Here are some key findings from their review:

  1. People who consumed the most fruit had a 17–24% lower depression risk than those who ate the least.
  2. Those who consumed the most vegetables had a 14–25% lower depression risk than those who ate the least.
  3. Every increase of 100 g in fruit intake was associated with a 3% reduction in depression risk.
  4. Every increase of 100 g in vegetable intake was associated with a 3–5% reduction in depression risk.

This study joins a growing body of research showing a strong connection between nutrition and mental health. Here at Truehope, we’ve been promoting nutrition as mental health treatment for over 20 years.
