EATING more fruit may help reduce the harmful effects of air pollution on lung function, according to a large UK Biobank study presented at the European Respiratory Society (ERS) Congress 2025. Diet and pollution examined in 150,000 participantsThe cross-sectional analysis included around 150,000 adults with complete data on diet, lung function, and air pollution exposure. Researchers used a healthy diet score (HDS) based on dietary patterns, alongside modelled annual average air pollution concentrations from the EXPANSE project. While no significant interactions were found between the overall diet score and pollution, fruit intake appeared protective, particularly in women, who reported higher average intakes. Does diet modify the effects of air pollution on lung function?
