Association between antioxidant vitamins and asthma outcome measures: systematic review and meta-analysis.
Asthma is less likely to occur among regular consumers of foods rich in vitamin A and C.
The objective of this study was to evaluate the relationship between dietary intake of antioxidant vitamins and the risk of developing asthma by meta-analysis. A total of 40 studies were included in this meta-analysis.
Researchers found a higher incidence of asthma in individuals with low dietary intake and serum concentrations of vitamin A and C than in persons with high plasma levels of vitamin A and C and people who consistently consumed foods high in vitamin A and C. Habitual consumption of foods rich in vitamin E did not have any significant effect on asthma risk in this study. The results of this study suggest that high consumers of vitamin A and C from dietary sources may have a low tendency of developing asthma.
