According to the Centers for Disease Control and Prevention, 17.5 million adults suffer from asthma. It is a disease that affects your ability to breathe. Wheezing, shortness of breath, coughing and tightening of the chest are all symptoms of asthma. When asthma occurs, the linings of the lungs become inflamed, which is accompanied by tight muscles that narrow the airways of the lungs. What you eat can help to prevent or reduce the likelihood of an asthma attack.

Antioxidants

Foods rich in antioxidant vitamins may help reduce symptoms associated with asthma. Antioxidants can help reduce inflammation by fighting free radicals. Free radicals are a product of normal bodily processes that occur when cells become oxidized. They are normally harmless, but an excess of free radicals can lead to disease and inflammation. Since asthma is a disease that is characterized by inflammation, antioxidants may reduce asthmatic attacks. Vitamins E and C are antioxidants that should be part of a healthy diet. Foods such as berries, pears, artichokes, broccoli and beans include a fair amount of antioxidants.

Your Weight

Excess weight can exacerbate your asthmatic symptoms. Losing weight can improve you asthma symptoms, according to a study published in the journal "Thorax" in 2008. This review analyzed studies conducted from January 1966 to 2007 and determined that in each case, weight loss was useful in improving asthmatic conditions. In fact, losing just a small amount of weight can reduce your symptoms. To control your weight, watch your calories and match it according to your level of physical activity.

Mineral Intake

Getting adequate intake of both calcium and magnesium, two essential minerals, can help improve your lung function. Both calcium and magnesium can help increase air flow in your lungs, according to a study conducted by the University of Nottingham in England. This study evaluated the lung function and diet of 2,600 people. Higher intakes of calcium and magnesium were associated with increased lung function. Milk, yogurt and leafy green vegetables are all good sources of both calcium and magnesium.

Maternal Diet

What you eat during pregnancy and your breastfeeding choices can affect the likelihood of developing asthma. According to a review published in "Respiratory Research" in 2009, antioxidant and fish-oil intake during pregnancy can help prevent the development of asthma for the developing fetus. These nutrients may work to properly develop airways and promote properly functioning immune function.
