A diet rich in fiber may not only protect against diabetes and heart disease, it may reduce the risk of developing lung disease, according to new research. Analyzing data from the National Health and Nutrition Examination Surveys, researchers report in “The Relationship between Dietary Fiber Intake and Lung Function in NHANES,” that among adults in the top quartile of fiber intake:
• 68.3% had normal lung function, vs 50.1% in the bottom quartile
• 14.8% had airway restriction, vs 29.8% in the bottom quartile.
In 2 important breathing tests, those in the top quartile had a greater lung capacity (FVC) and could exhale more air in one second (FEV1)r.
“Lung disease is an important public health problem, so it’s important to identify modifiable risk...
