COPD is a respiratory condition in which the airways become narrowed and can include bronchitis and emphysema.
Each additional daily serving of fruits and vegetables consumed by smokers and ex-smokers is associated with a 4% to 8% lower risk of developing chronic obstructive pulmonary disease, a recent study found. The study, published in the journal Thorax, involved more than 44,000 Swedish men, aged 45 to 79, who completed detailed questionnaires about health and nutrition.
Almost two thirds of the participants had smoked at some point in their lives, and about one in four were current smokers. During the 13-year study, 1,918 new cases of COPD were identified. Men who ate five or more servings of fruit and vegetables a day were 35% less likely to develop lung disease than those who ate two servings or less. No additional benefit was observed for nonsmokers.
Because smoking increases oxidative stress and inflammation, which are potentially involved in COPD, the antioxidants found in fruits and vegetables may help reduce the negative effects, the researchers point out.
"Even if smokers can't quit, they should eat more fruits and vegetables, and people who are quitting should also increase their intake," said Joanna Kaluza, the study's lead author and a professor of Life at the University of Warsaw in Poland.
She added that the protective effect of fruit and vegetables is likely to apply to women as well, explaining that while apples, pears, green leafy vegetables and peppers appear to exert the strongest impact and reduce disease risk, no effect was found. related to berries, bananas, citrus fruits, cruciferous vegetables, tomatoes, onions, garlic or peas.
