Oxidants
Cross-sectional and case studies have suggested that diet may play an important role in the origin and progression of asthma. Rubin and coworkers measured serum levels of antioxidants in 7,505 youth in the Third National Health and Nutrition Examination Survey. They found that an SD increase in ß-carotene, vitamin C, and selenium was associated with a 10 to 20% reduction in asthma prevalence. Serum vitamin E had little or no association with asthma. The apparent benefit of selenium was even greater in youth with passive exposure to cigarette smoke. The authors suggested that serum antioxidants may be important in the prevention of asthma onset and/or the progression of asthma.
