Dietary fiber has a glowing list of health accolades, and guarding against depression may be yet another to add to the list. In a study that involved more than 5,800 adult women, those who were premenopausal and consumed the most fiber were significantly less likely to develop depression.
The scientists believe a likely connection between fiber and depression lies in the microbiome, our vast ecosystem of gut microbes. Consuming an abundance of fiber is essential for maintaining a robust and diverse microbiome, which in turn is tied to superior mental well-being.
This study echoes several past studies showing a positive relationship between fiber intake and superior mood. So, if depression is an issue for you, step up your intake of whole plant foods (fruits, veggies, beans, and whole grains) to ramp up your fiber intake.
