MAC lung disease is caused by MAC bacteria (Mycobacterium avium complex) living in the soil and water. They generally affect people with compromised immunity and respiratory ailments, causing symptoms like chronic cough, hemoptysis, fatigue, low-grade fever, shortness of breath, chest pain, and anxiety, which may impede daily activities. Eating the right foods and avoiding the wrong ones is crucial to maintaining one’s quality of life. Here are 13 foods to avoid for MAC lung disease. Dairy People with MAC lung disease must avoid dairy products despite their rich calcium content. This is because dairy has been known to impact respiratory health. According to some studies, drinking milk may increase mucus production, leading to congestion. Consuming cheese may also lead to the release of histamines, which can cause airway inflammation. Salty foods Foods rich in sodium chloride (or salt) can lead to water retention in the body. This can lead to shortness of breath among those who live with lung disease. Apart from cutting back on table salt, one must also check the ingredients in packed foods, seasonings, and dressings. Confirm that these do not contain more than 300 milligrams of salt per serving. Alternatively, opt for herbs and spices to season food.
