The Relationship between Dietary Fiber Intake and Lung Function in the National Health and Nutrition Examination Surveys

Increased consumption of foods high in fiber may have a positive impact on lung function in men and women.

This study evaluated the effect of high dietary ingestion of fiber on lung function. Researchers compared fiber consumption rates with the spirometry measurements of 1,921 US men and women.

Researchers discovered that regular eaters of generous portions of fiber-containing foods had better lung function than participants who ate little or none of these plant foods. The results of this study show that adhering to a diet that promotes the intake of fiber-rich foods may help improve lung function in men and women.
