Diets rich in fruit ‘can improve lung health among former smokers’

21st December 2017

Eating more fruits may help to improve lung function among people who have quit smoking, according to new research.

A study from the Johns Hopkins Bloomberg School of Public Health has assessed dietary trends and lung function among more than 650 adults over a ten-year period, revealing that natural declines in lung function were slower among former smokers with a diet high in fruits.

Tomatoes and apples were cited as examples of fruits that offered pronounced benefits, suggesting certain components in these foods might help restore lung damage caused by smoking.

Adults who ate more than two fresh tomatoes or more than three portions of fresh fruit a day had a slower decline in lung function, a trend that was not replicated with dishes and processed foods containing fruits and vegetables.

A slower decline in lung function was also seen among all adults with the highest tomato consumption, including those with no history of smoking.

Vanessa Garcia-Larsen, assistant professor in the Bloomberg School's Department of International Health, said: "This study shows that diet might help repair lung damage in people who have stopped smoking. It also suggests that a diet rich in fruits can slow down the lung's natural ageing process even if you have never smoked."
