SUN-PP159: The Relationship between Dietary Fiber Intake Low Fev1 in Nhanes

Healthy Diets and Lung Health. Connecting the Dots

“…In this month's issue of AnnalsATS, Hanson and colleagues (pp. 643-650) place lung function in the context of overall health, using data from the National Health and Nutrition Examination Surveys (1). They document that participants with the greatest intake of dietary fiber had the highest lung function and also were more likely to have normal lung function.…”

“…Limiting the study of lung function to the context of disease limits the scope of our understanding how differences in lung function, even within the normal range, affect both overall health and disease. By not focusing exclusively on disease and also examining dietary predictors of lung health, Hanson and colleagues make a meaningful contribution to the overall study of lung health (1).…”

“…Notwithstanding known effects of dietary fiber on laxation and care and feeding of bacteria and other organisms in the gut microbiome, dietary fiber (and specifically cereal fiber) is more likely to be a marker of a good diet than to be an active constituent of the good diet (18). The fact that the A priori Diet Quality Score and the Alternate Healthy Eating Index both predicted noncardiovascular, noncancer inflammatory-related causes of death (15) is relevant to the work of Hanson and colleagues, because this broad classification includes lung-related conditions and dementia (1).…”

Dietary patterns and asthma among Peruvian children and adolescents

“…Additionally, fruits and vegetables as well as whole grains high in fiber could exert antiinflammatory effects due to the production of short chain fatty acids, including butyrate, by microbiota in the gut through the fermentation of fiber [43]. Although the relationship between fiber intake and respiratory outcomes has been more commonly conducted in chronic obstructive pulmonary disease [44,45], there are studies evaluating fiber intake in asthma. Berthon et al showed that fiber intake was 5 g a day less in asthmatics when compared to controls, and fiber intake in asthmatics was positively associated with lung function [46].…”
