When it comes to health, what you introduce into your body and environment holds great importance. This holds for lung health as well. With increased levels of air and water pollution surrounding us, impaired lung capacity is a growing concern. In such a scenario, avoiding foods that could further contribute to the deterioration of your lungs is necessary. Avoiding foods that can compromise lung health can also help maintain heart health. Processed meat Increased intake of highly processed meats like bacon, sausages, hot dogs, and other deli meats has long been linked to compromised lung health. According to numerous research results, daily intake of processed forms of meat can impair lung function, increasing the risk of developing and triggering conditions like COPD. A set of research also found the rehospitalization rate to be higher in COPD patients that continued using processed meat. The problem is the high salt content and the subsequent water retention these foods can cause. Added sugar Sugars that are not naturally present in food and have been added as a measure of taste enhancement or preservation are added sugars. Most often, it is in the form of refined sugar or other syrups. Commonly occurring foods with added sugars include cereals, granola, cakes, flavored yogurts, and more.
