The lungs are paired organs in the chest responsible for respiration. When lung health decreases, the results can be debilitating. Conditions that affect the lungs include asthma, chronic bronchitis, emphysema and lung cancer. According to the National Lung Health Education Program, numerous factors contribute to these conditions, including heredity and lifestyle habits. While healthy foods cannot prevent inherited illnesses or cure lung diseases, they may promote lung health and reduce the effects of associated illnesses.
Vitamin A-Rich Foods
Vitamin A refers to a group of compounds that contribute to healthy vision, reproduction, bone development and immune system function. According to the Office of Dietary Supplements, vitamin A also supports healthy linings of the respiratory tract. As a result, foods rich in vitamin A are associated with reduced risk for lung-related infections and diseases. Vitamin A derives from animal-based foods, such as meat, poultry and dairy products, and from vegetable sources, such as carrots, leafy greens, cantaloupe and apricots. The animal-derived forms are more easily absorbed by humans than plant-based sources, according to the Office of Dietary Supplements. However, a variety of both forms is suggested for optimum wellness.
Fatty Fish
Fatty fish, such as salmon, albacore tuna, lake trout, sardines and mackerel, provide rich amounts of omega-3 fatty acids--healthy fats the body must obtain from food. According to research published in the Journal of the American College of Nutrition in 2002, omega-3 fats derived from fish oil may have a positive impact on lung health in children with asthma. In some cases, omega-3 fat intake has allowed individuals faced with chronic lung inflammation to require smaller amounts of anti-inflammatory medication. Omega-3 fats also support nutrient absorption and overall cardiovascular health. People who do not consume fish regularly can reap similar benefits from ground flaxseed, walnuts and canola.
Antioxidant-Rich Foods
Antioxidants are nutrients that work to reduce harmful agents known as free radicals from the body. According to the American Cancer Society, antioxidants may help prevent tissue damage and reduce risk for various forms of cancer, such as lung cancer. Antioxidants are found in colorful fruits and vegetables, such as blueberries, strawberries, papaya, oranges, prunes, plums, red grapes, apples, spinach, kale, Brussels sprouts, sweet bell peppers and artichokes. Legumes, such as kidney beans and pinto beans, and whole grains, also provide valuable amounts. Though antioxidants are available in supplement form, the cancer society recommends food sources as the most helpful, proven means of improving health and lowering cancer risk.
