- Air pollution (PM2.5 and PM10) accelerates biological aging via oxidative stress and inflammation.
- Plant-based diets (Sustainable Diets) may mitigate the effects of air pollution on biological aging.
- The study involved 9,527 participants from the Guangzhou Biobank Cohort Study, with a mean age of 64.6 years.
- Higher PM2.5 and PM10 exposure was associated with increased phenotypic age and accelerated aging.
- Greater adherence to sustainable diets (higher PDI/PHD scores) weakened the association between air pollution and aging.
- Stronger associations between pollution and aging were found in individuals with lower genetic predisposition to longevity.
- A suggestive link was observed between higher PM exposure and shorter relative telomere length (RTL), especially in older adults and those with cardiovascular diseases.
- Sustainable diets rich in plant-based foods may help reduce the aging burden caused by air pollution.
