Although you may not be able to feel it, your lungs are almost constantly under attack from inhaled pollutants, airborne pathogens and free radicals. Also, your lung cells are high-maintenance, requiring large amounts of vitamins and minerals to stay healthy. Consuming a healthy diet can help shield your lungs from harm and promote overall lung function.
Calories
Losing weight can help boost lung function in overweight people, the European Lung Foundation reports. Extra weight makes is more difficult for your lungs to perform the physical act of inhaling and exhaling. The ELF states that reducing obesity rates could prevent more than one-third of all asthma cases. In addition to exercising regularly, consuming adequate calories is an important aspect of weight management. If you need to lose weight, check in with your physician to discuss treatment options appropriate for you.
Omega-3 Fats
Healthy omega-3 fatty acids reduce inflammation in the lungs, helping your lungs breathe easier. Omega-3 fats may also help reduce the risk of cancerous cell formation in the lungs. However, the ELF notes that the majority of adults don't consume the omega-3 fats they need in their diets. Natural sources of omega-3 fats include tuna, soybeans, black beans, flaxseeds and walnuts. If you take medication for high blood pressure, talk to your doctor before increasing your omega-3 fat intake as this may interfere with the action of your medication.
Antioxidants
Antioxidants shield your vulnerable lung cells from the damage caused by oxidation. Oxidation can occur by breathing in pollutants or tobacco smoke. In general, fresh produce with dark pigmentation tends to be rich in antioxidants. Especially antioxidant-rich foods include blueberries, apples, spinach, olive oil, mangoes and bell peppers. For overall health, aim to consume at least nine fruit and veggie servings daily, Harvard School of Public Health advises.
Sodium
Restricting sodium intake is an important part of a diet to improve lung function. According to the ELF, consuming excessive sodium can restrict the airways in those with breathing problems like asthma. Additionally, sodium can result in fluid retention -- making it more difficult for your lungs to work. Sodium-rich foods to avoid include frozen dinners, fast food, baked goods and canned vegetables.
