Higher diet quality linked to improved lung function in asthma, COPD
Higher diet quality is associated with better lung function (LF), especially among individuals with asthma or chronic obstructive pulmonary disease (COPD), according to a study published in ERJ Open Research.
A recent study published in ERJ Open Research has found that higher diet quality is linked to improved lung function, especially among individuals with asthma or chronic obstructive pulmonary disease (COPD). Researchers from the University of Groningen in the Netherlands analyzed data from the Lifelines cohort study, which assessed diet and lung function among adults.
They utilized the Lifelines diet score (LLDS) to calculate dietary quality, and measured lung function via prebronchodilator spirometry at baseline and two follow-ups around 10 years apart. The study revealed that higher LLDS was associated with better lung function and slower decline in both asthma and COPD patients compared to those without these conditions.
In a longitudinal analysis of 37,752 participants, higher LLDS was linked to a slower decline in FEV1, FVC, and FEV1/FVC in COPD patients compared to non-COPD individuals. These findings suggest that diet could be a modifiable lifestyle factor that positively impacts respiratory health, with a particular relevance for COPD patients.
