We read with interest the recent finding by Park et al1 that dietary fiber was associated with a 69% and 54% lower risk of death from respiratory diseases among men and women, respectively, using data from the National Institutes of Health (NIH)-AARP prospective cohort. As indicated by the authors, anti-inflammatory properties of dietary fiber may contribute to the observed associations. Summarized herein are previously reported findings from 2 prospective cohorts, the Singapore Chinese Health Study (SCHS)2 and the US Atherosclerosis Risk in Communities (AIRC) study,3 that support a beneficial effect of higher fiber intake in the development of respiratory morbidity.
