Numerous factors can inhibit healthy lung function, including lifestyle, heredity and habits, according to the National Lung Health Education Program. While a healthy diet cannot cure or prevent lung disease, it may reduce associated symptoms or promote lung health.
Fatty Fish
Fatty fish such as albacore tuna, salmon, sardines, mackerel and lake trout provide large amounts of omega-3 fatty acids, essential fats obtained from foods. Omega-3 fats derived from fish oil and other products may produce a positive impact on lung health, particularly in children with asthma, reports the Journal of the American College of Nutrition. In some cases, the consumption of omega-3 fats allowed patients with chronic lung inflammation to reduce their anti-inflammatory medication. In addition, omega-3 fats also support cardiovascular health and nutrient absorption. People who do not consume fish on a regular basis can reap similar benefits from canola, walnuts and flaxseed.
Vitamin A-Rich Foods
Vitamin A refers to nutrient compounds that contribute to reproduction, healthy vision, immune system functions and bone development. Vitamin A supports healthy respiratory tract linings, according to the Office of Dietary Supplements. As a result, foods high in vitamin A are associated with lowered risk for lung-related diseases and infections. Vitamin A from animal-based foods include poultry, meat, diary products, carrots, cantaloupe, leafy greens and apricots. According to the Office of Dietary Supplements, the human body absorbs animal-derived forms of vitamin A better than plant-based sources. A variety of both forms is recommended for dietary wellness.
Antioxidant-Rich Foods
Antioxidants work to lower harmful agents or free radicals in the body. Antioxidants may also reduce lung cancer risk and prevent tissue damage, according to the American Cancer Society. Vegetables and fruits such as Brussels sprouts, papaya, blueberries, oranges, red grapes, prunes, apples, kale, strawberries, artichokes and sweet bell peppers contain these powerful nutrients. Legumes such as pinto beans and kidney beans provide valuable amounts of antioxidants. Although antioxidants are widely available in supplement form, the American Cancer Society recommends food sources to improve health and lower cancer risk.
