- Air pollution was tied to reduced lung function in UK Biobank patients.
- Higher fruit intake was linked to smaller declines, mainly in women.
- A healthy diet score improved lung function but did not alter pollution effects.
- Researchers adjusted for demographics, lifestyle, and socioeconomic factors.
- Study limitations included cross-sectional design and self-reported diet data.
- Pimpika Kaewsri, PhD, University of Leicester: “Total fruit intake seems to mitigate adverse effects of PM2.5 on lung function.”
