- Vitamins: Some research suggests that getting ample amounts of vitamins A, C, D, and E may help reduce asthma symptoms.
- Minerals: Some studies have found that people with asthma are deficient in magnesium and selenium.
- Omega-3 fatty acids: These fats fight inflammation, which may help reduce asthma symptoms.
- Flavonoids: In one study, people who had high intakes of flavonoids -- powerful antioxidants found in onions, tea, and citrus fruit -- had lower rates of asthma.
While you're eating better, remember to limit intake of any foods or ingredients known to trigger your asthma. For example, some people find that their symptoms are triggered by the sulfites in dried fruit.
