Getting an adequate amount of fiber each day could help middle-aged people breathe easier.It also appears to be a benefit to non-smokers and smokers alike, according to a study in the American Journal of Epidemiology.

In the study, those with the highest levels of daily fiber intake had better lung function and were less likely to have chronic obstructive pulmonary disease, also known as COPD.

The beneficial links remained even after accounting for other factors that may impact lung function.
