Dietary fiber reduces asthma

A high-fiber diet reduces the severity of allergic airway disease, including decreased lung inflammation, in mice according to a study published online in Nature Medicine. These findings highlight how diet can influence immune cell development and disease outside of the gut.Over recent decades, the incidence of allergic asthma has increased in developing countries, while the consumption of dietary fiber has decreased in these countries. Although dietary fiber intake can improve gastrointestinal disorders, it remains unclear whether it influences inflammation outside of the gut.
