Not getting enough fresh fruit and vitamin C in your daily diet can up the risk of developing asthma, a new British study finds. Conducted by researchers at Cambridge’s Medical Research Council, the study was published in a recent issue of the journal Thorax. Researchers monitored more than 500 adults over the course of a year, finding that those with the lowest fresh fruit consumption and overall vitamin C intake were twice as likely to develop asthma as the patients who consumed the most fruit and vitamin C. The relationship between low fruit and vitamin C consumption and asthma risk held even among those patients who otherwise engaged in healthy habits such as exercise and caloric moderation.
