The lungs are one of the most vital organs in the human body. Thus, they must remain in good shape to live a healthy life. However, many foods can unknowingly cause them harm and worsen breathing difficulties, whereas adding the proper nutrients to the food regime can help one breathe easier and minimize symptoms of conditions like asthma and COPD. Here are some of the worst foods for lung health that may worsen breathing difficulties: Processed meat Processed meats such as bacon, ham, hot dogs, sausages, and other lunch meats are often treated with additives and preservatives to add flavor and extend their shelf life. This can harm lung health and function. According to certain research, processed meats have been linked with an increased risk of chronic obstructive pulmonary disease (COPD), which may cause breathing difficulties. Additionally, processed meats also contain sodium nitrite, a known carcinogen that can increase one’s susceptibility to lung cancer. Vegetable oil Vegetable oils are used in most households to cook food. However, certain oils, such as canola oil, soybean oil, corn oil, sunflower oil, grapeseed oil, and safflower oil, can be dangerous for the lungs. This is because they contain unhealthy fats that can lead to heart disease, increased inflammation, and excessive mucus production, which may impact one’s breathing.
