PARIS: Adults who ate more than two tomatoes a day had a slower rate of natural lung function decline, with ex-smokers seeming to benefit most of all, scientists said Thursday. Similar benefits, they said, were observed for people who ate more than three portions of fresh fruit a day, especially apples. ?This study shows that diet might help repair lung damage in people who have stopped smoking,? study co-author Vanessa Garcia-Larsen of the Johns Hopkins Bloomberg School of Public Health in Baltimore said in a statement. ?It also suggests that a diet rich in fruits can slow down the lung?s natural ageing process even if you have never smoked.?
