Depression affects more than 300 million people worldwide and is a significant contributor to psychological disorders. It is widely acknowledged that dietary fiber is a crucial component of a healthy diet; however, in many countries, dietary fiber intake remains consistently insufficient. Increasing fiber intake can help prevent cardiovascular disease, and recent studies suggest that it can also play a role in preventing diabetes and metabolic syndrome. Dietary fiber is essential for a healthy diet because it promotes the activity of intestinal flora and the production of beneficial by-products. A high-fiber diet may reduce inflammation by influencing intestinal pH and permeability. This reduction in inflammatory compounds may alleviate symptoms of depression.
