More dietary fiber for healthier lungs
The more dietary fiber there is in your diet, the healthier your lungs are. That is the purport of an epidemiological study published in the Annals of the American Thoracic Society in 2016.
Nebraska Medical Center epidemiologists analyzed data from 1,921 Americans ages 40-79 who had participated in the National Health and Nutrition Examination Surveys (NHANES).
Between 2007 and 2010, the researchers had determined the lung function of the study participants. In addition, they had obtained an impression of the dietary patterns of the study participants by means of questionnaires.
The more dietary fiber the study participants consumed daily, the more likely they were to have healthy lungs. At the same time, as the intake of dietary fiber increased, the risk of malfunctioning lungs decreased.
When it comes to dietary fiber, educators like to emphasize whole-grain and fiber-rich grain products such as whole-wheat bread and whole-wheat pasta. So the researchers looked at that too. However, they could not find an association between whole-grain cereal intake and lung health. They did, however, find a link between lung functioning and fruit and vegetable intake.
"A diet rich in fiber-containing foods may play a role in improving lung health", the researchers write.
