Air pollution is an everyday reality for millions of people, especially in cities. But new research suggests that something as simple as eating more fruit could help protect the lungs from its harmful effects.
Fruit as a natural shield
Antioxidants and anti-inflammatory compounds in fruit may help reduce the damage caused by pollution in the lungs.
Large-scale data
The study drew on data from nearly 200,000 people to examine the link between diet, air pollution, and lung function.
Pollution measured as PM2.5
Researchers focused on fine particulate matter from traffic and industry, known as PM2.5, which can penetrate deep into the lungs.

Stronger effect in women
Women who consumed more fruit had smaller reductions in lung function when exposed to polluted air compared to those who ate less.
Four portions a day
The protective effect was most evident among those eating at least four portions of fruit per day.
Less decline in capacity
Participants with higher fruit intake showed a smaller loss of lung capacity than those with lower intake.
Benefits for men too
Although the most noticeable results were in women, the study also linked fruit intake to better lung function in men.

Role of blood vessels
Both lungs and other organs rely on delicate networks of blood vessels, which fruit compounds may help protect.
Social differences matter
Experts warn that not everyone has equal access to fresh fruit, which may explain health disparities across populations.
Not a replacement for policy
While diet can help, researchers stress that governments must continue to reduce pollution, since no level is considered safe.
A step toward prevention
The findings highlight how fruit may not only benefit overall health but also provide a valuable buffer against the harmful effects of polluted air on the lungs.
