Lung function is a predictor of mortality in the general population, as well as in patients with lung disease, even in those who have never smoked. Maintaining lung function is an important goal in the prevention of chronic respiratory diseases and a major public health objective; yet, smoking cessation remains the main target to reduce the burden of these diseases.
The possible modulatory effect of diet on lung health has been investigated in several epidemiological studies, suggesting that dietary intake of various sources of antioxidants are associated with improved ventilatory function outcomes in adults. Evidence has shown a positive association between forced vital capacity (FVC) and higher fruit and flavonoid intake in young, middle-aged and elderly adults.
Similarly, in older adults, a “prudent” dietary pattern, characterized by a higher intake of fruits and vegetables, has been associated with better lung function and a lower prevalence of chronic obstructive pulmonary disease (COPD).
