Fruit consumption, lung function, and wheezing in children:
Wheezing and dietary modifications: In the cross-sectional study of 2,650 children aged 8-11 years old in the UK, Cook and colleagues reported that forced expiratory volume in 1 second (FEV1), a measure of lung function, was positively linked with the frequency of fresh fruits, green vegetables, and salad consumption but was not associated with blood vitamin C levels. The beneficial effect was strongest from fruit consumption. Compared to children who never ate fresh fruit, those who ate fresh fruit more than once a day had a 79 ml or 4.3% higher FEV1 value. This link between FEV1 and fruit intake was stronger in children with wheeze than those without. (52)
