Diet rich in apples and tomatoes may help repair lungs of ex-smokers, study suggests

Study also found that regular intake of tomatoes may also help slow the natural decline in lung function among all adults

"The researchers found that adults who on average ate more than two tomatoes or more than three portions of fresh fruit a day had a slower decline in lung function compared to those who ate less than one tomato or less than one portion of fruit a day, respectively. The researchers inquired about other dietary sources such as dishes and processed foods containing fruits and vegetables (e.g. tomato sauce) but the protective effect was only observed in fresh fruit and vegetables."
