Lungs are responsible for delivering oxygen to the body and protecting the airways from irritants. One’s eating habits and lifestyle play an important role in maintaining lung health. For strong lungs, it is necessary to expose oneself to fresh, pollution-free air and choose nutrient-rich foods that boost energy and health. The absence of either can lead to impaired lung functionality and problems like asthma. Here are four foods to avoid for optimal lung health:

Sugary foods
Refined sugar is usually added to foods for preservation and taste enhancement. Excessive amounts of this ingredient can be found in sweetened drinks, syrups, cakes, donuts, cereals, flavored yogurt, granola, chocolates, and candies. Studies show that those who regularly opt for sugary foods and drinks have a high chance of developing bronchitis. Excessive intake of refined sugar also increases the fat content in the body and eventually puts pressure on the lungs and heart, leading to impaired functioning of the organs.

Carbonated beverages
Similar to refined sugar, carbonated beverages tend to put undue pressure on one’s lungs. These drinks have no nutrients and contain empty calories, carbon dioxide, and sugar. According to the American Lung Association, these drinks can generate gas, which can impede breathing, tighten the chest, or trigger asthma flare-ups. Carbonated beverages contain trans fats and lead to bloating and stomach aches. These foods are especially harmful to those with lung diseases.

Processed meat
Processed meats include sausage, deli meat, ham, hot dogs, bacon, and ham. Numerous studies show that the nitrites used in curing and preserving meats can exert stress on the lungs and lead to inflammation. Additionally, daily consumption of processed meat can increase one’s risk of developing and aggravating illnesses like chronic obstructive pulmonary diseases. COPD refers to lung conditions that block airflow and make breathing difficult. Processed meats also contain high levels of sodium for preservation and flavor. This can lead to water retention and make one susceptible to bronchitis and asthma. So, it is best to avoid packaged and processed foods. Those who experience COPD flare-ups due to chronic bronchitis and emphysema can opt for the Spiriva Respimat COPD inhaler after consulting a doctor. The Spiriva Respimat inhaler relaxes one’s airways, keeps them open, and helps better one’s breathing.

Fried foods
Oily foods contain high levels of trans fats and are best avoided for one’s overall health. Foods like fries and chicken wings can add to the saturated fat content in the body and cause indigestion, bloating issues, stomach gas, and even breathing troubles. Fried foods are also linked to episodes of asthma, COPD, and other complex lung health concerns. One can substitute fried foods with baked or air-fried versions to limit oil.

One should also limit foods that cause gas and bloating, including beans, garlic, and onion. Those affected by asthma or other lung diseases can further avoid dairy products like milk, cheese, and yogurt to cut down on mucus production. One should consult a doctor and get a customized plan if affected by breathing-related issues.

Those diagnosed with MAC lung disease may require treatment besides nutritional changes. MAC lung disease is a type of nontuberculous mycobacterial (NTM) infection caused by the mycobacterium avium complex (MAC) bacteria. Treatments for this condition depend on the severity of the symptoms. MAC bacteria typically reside in soil and water and are more likely to affect those with immuno-compromised systems. Those at risk should eat healthy foods, wear a dust mask, follow an aggressive airway clearance regimen, and avoid hot tubs and saunas.
