A mycobacterium avium complex infection, commonly known as MAC disease, is a type of rare lung disease that affects 1 person per 100,000 each year. The symptoms of MAC disease normally include fever sweating, fatigue, weight loss, diarrhea, shortness of breath, anemia, and abdominal pain. While there are ways to manage MAC disease symptoms, it is important to have these five foods for better lung health and better disease management. Salmon Salmon, mackerel, anchovy, herring, and other fatty fish are rich in omega-3 acids. This nutrient has been long associated with better lung health, among other benefits. Omega-3 fatty acids help fight inflammation due to infections and reduce the risk of such conditions worsening over time. Apricots This food can be particularly helpful in managing lung infection and addressing the symptoms of MAC disease. The abundance of vitamin A in apricots is known to lower the risk of lung infection by repairing the respiratory tract lining. Beef liver, cod liver oil, carrots, black-eyed peas, broccoli, spinach, carrot, and sweet red peppers are other vitamin-A-rich foods one can have for better lung health. Olive oil Olive oil contains vitamin E in the form of the nutrient alpha-tocopherol that is associated with enhancing lung functionality.
