Research suggests that eating four or more portions of fruit per day can help mitigate the decline in lung function caused by exposure to fine particulate pollution. The antioxidants and anti-inflammatory compounds present in fruit may help offset the harmful effects of air pollution on the lungs. While specific fruits were not singled out in the study, previous research has shown that apples, tomatoes, berries, grapes, and pomegranates, rich in polyphenols, are associated with healthier respiratory function.

Experts emphasize that while a plant-rich diet, including fruits, can offer some protection for the lungs, it is not a substitute for systemic policies to reduce air pollution. Governments should continue to prioritize environmental policies to minimize exposure levels, especially since access to healthy food options is not evenly distributed. Ultimately, a combination of a healthy diet and clean air policies is essential for maintaining lung health in a world where clean air is not guaranteed.
