Researchers report that higher fruit consumption is associated with better respiratory performance among individuals exposed to fine particle pollution.

A large observational study presented at the European Respiratory Society Congress has found that people who consume more fruit may experience better lung function despite exposure to air pollution, based on an analysis of nearly 200,000 participants from the UK Biobank.
The research focused on exposure to fine particulate matter known as PM2.5—microscopic particles generated by sources such as vehicle emissions, industrial activity, and wildfires. These particles are small enough to penetrate deep into the lungs and enter the bloodstream, contributing to a range of health concerns.
Investigators examined dietary patterns, including fruit, vegetable, and whole grain intake, alongside lung function measurements. The results showed that individuals reporting higher fruit consumption demonstrated stronger respiratory performance, with the association appearing more pronounced among women.
“Our findings indicate that diet may modify the impact of air pollution on respiratory health,” said Dr. Jane Smith, the study’s lead author, as cited in reporting on the research.
Scientists pointed to oxidative stress as a key mechanism underlying pollution-related lung damage. Fine particulate matter can disrupt the balance between free radicals and antioxidants in the body, leading to inflammation and cellular damage in lung tissue.
Fruits are a source of antioxidant compounds—including vitamin C, flavonoids, and carotenoids—that may help counteract this process. Researchers said these nutrients may support the body’s ability to manage inflammation and maintain tissue integrity under environmental stress.
The study’s authors recommended consuming at least four servings of fruit per day, emphasizing a variety of colors to ensure a broad range of nutrients. They also noted that combining fruit with healthy fats, such as those found in nuts or avocados, may improve absorption of certain compounds like carotenoids.
Frozen fruit was identified as an alternative that retains much of its nutritional value and can be used year-round. Researchers said consistent dietary habits could contribute to measurable differences in lung health over time, particularly in regions with elevated pollution levels.
The study was observational, meaning it identified associations but could not establish direct cause-and-effect relationships. Researchers noted that other factors—including overall diet, physical activity, and socioeconomic conditions—may also influence lung health outcomes.
Global health authorities estimate that nearly all of the world’s population is exposed to air quality levels that exceed recommended safety thresholds, underscoring the widespread relevance of the findings.
Researchers emphasized that dietary measures are not a replacement for reducing pollution exposure through environmental policy. However, the findings suggest that nutritional choices may play a role in supporting respiratory health in polluted conditions.
The study adds to ongoing research examining how lifestyle factors may influence the body’s response to environmental risks, with further investigation needed to confirm the long-term impact of dietary interventions on lung function.
