Eating more fruits and vegetables could reduce the risk of developing chronic obstructive pulmonary disease (COPD), according to a Swedish study. Researchers have shown that antioxidants in plants help protect the lungs from the damage caused by smoking. “All smokers and former smokers should eat as much fruit and vegetables as possible,” said Joanna Kaluza, lead author of the study published in Thorax magazine .
The Karolinska Institute team in Stockholm (Sweden) studied data for 44,335 middle-aged and older men. None of the participants included in the analysis had COPD at the first assessment. The researchers followed these volunteers from 1998 to 2012. Nearly two-thirds of the men were current or former smokers and 1,918 had acquired lung disease during research.
