Eating apples and tomatoes may help prevent respiratory disease. Researchers at the University of Nottingham studied the lung function of 2,633 adults in 1991 and again in 2000, using spirometry to measure forced expiratory volume in one second (FEV-1). Eating more than five apples each week was strongly associated with increased FEV-1, as was having tomatoes more than three times a week. Wheezing was also less common among people who consumed apples, tomatoes and bananas. The authors theorise that the high levels of antioxidants in these foods may have a beneficial effect on lung function. (97th Annual Meeting of the American Thoracic Society).
