Researchers from the University of Leicester in the U.K. discovered that eating a high intake of fruit may reduce the effects of air pollution on lung function. "Ample research shows that exposure to higher air pollution levels is associated with reduced lung function," Kaewsri said. "We wanted to explore whether a healthy diet or specific food groups could modify or partly mitigate the known adverse effects of air pollution on lung function," Kaewsri said. The researchers also factored in exposure to air pollution in the form of fine particle matter from sources including vehicle exhaust and industrial processes. For women in the high fruit intake group, lung function was only reduced by 57.5 milliliters.
