Asthma is a respiratory condition characterized by inflammation of the airways, excessive mucus and difficulty breathing. Wheezing, coughing, chest tightness and shortness of breath are some of the common signs and symptoms you may experience. Your symptoms may be triggered by allergens, such as peanuts, shellfish, smoke, pet dander, insects, dust mites, pollen, cold air or sulfites used as food preservatives. Asthma is manageable, and fruits and vegetables may help.
Antioxidants
Fruits and vegetables are rich sources of antioxidants, substances that boost your immune system, may increase the functioning of your lungs and reduce asthma symptoms. Low blood levels of antioxidants, such as carotene and vitamin C, are observed in patients with severe asthma, according to research published in "European Respiratory Journal" in 2005. Research published in "Thorax" in 2006 discovered that symptomatic asthma in adults is associated with a low dietary intake of fruit, particularly citrus fruits, and antioxidant nutrients, such as vitamin C and manganese. The research also found low plasma levels of vitamin C in adults with asthma.
Fruits & Vegetables in Childhood
Fruits and vegetables provide essential vitamins, minerals, antioxidants and fiber that reduce your risk of chronic disease. Fruits and vegetables are also low in fat and calories. The Centers for Disease Control and Prevention recommends that you eat a colorful variety of fruits and vegetables each day to ensure you meet your nutritional needs. Fruits and vegetables may also reduce your risk of asthma and symptoms if you suffer from the condition. Early introduction of daily fresh fruit and vegetables during infancy decreases the risk of asthma after one year of life, according to research published in "Acta Paediatrica" in 2005. Research published in the "European Respiratory Journal" in 2010 discovered that fruit consumption at an early age is associated with reduced asthma symptoms and long-term fruit intake is associated with fewer asthma symptoms and sensitization to inhalant allergens.
Mediterranean Diet
A Mediterranean diet comprises fresh fruits and vegetables, nuts, seeds, legumes, whole grains, olive oil and fish. A Mediterranean diet adapted by people in the United States reduces risk of death from all causes, including cardiovascular disease and cancer, according to research published in "Archives of Internal Medicine" in 2007. Research published in "Thorax" in 2007 observed that a high level of adherence to the Mediterranean diet, particularly fruits and vegetables that are consumed at least twice per day, is protective for common symptoms of asthma, including wheezing and allergies.
