An apple a day may be good for your lungsJanuary 18, 2000Overall, good lung function was associated with high intakes of vitamins C, E, and beta-carotene, citrus fruits, apples, and fruit juices. After adjusting for factors, such as body mass, smoking history, and exercise, only the association with apples remained, suggesting that eating five or more apples a week, compared with none, was associated with slightly better lung function. There was no evidence to suggest that the natural decline in lung function with age could be slowed by short term increases in the number of apples eaten. Eating a lot of apples might simply reflect a healthy diet, suggest the authors. But apples contain high levels of an antioxidant flavonoid called quercetin which is also found abundantly in onions, tea and red wine, and may be important in protecting the lungs from the harmful effects of atmospheric pollutants and cigarette smoke.
