High-Fiber Diet Good for Lungs

A high-fiber diet protects lung function, according to a study published online in the Annals of the American Thoracic Society. Researchers monitored dietary fiber intake and lung function in 1,921 participants from the National Health and Nutrition Examination Surveys (NHANES). Those who consumed more than 17 grams of fiber per day from fruits, vegetables, and legumes had better lung health, compared with those who consumed the least. This study supports previous research that showed fiber’s association with a reduction of inflammation, a cause of lung disease.
