Everyday Foods That Alleviate Symptoms of Chronic Obstructive Pulmonary Disease

SadaNews - A US study has indicated that incorporating simple foods into the daily diet, such as legumes and soy products, may help alleviate symptoms of chronic obstructive pulmonary disease (COPD) by reducing inflammation and improving lung function.

According to researchers from Johns Hopkins University, the study confirms that diet is not a secondary factor but can be an essential part of managing respiratory diseases. The results were published on Thursday in the journal "Chronic Obstructive Pulmonary Diseases."

COPD is considered one of the chronic respiratory diseases that affect the lungs and lead to persistent difficulty in airflow, causing symptoms such as shortness of breath, chronic cough, and increased mucus production. This disease includes conditions like chronic bronchitis and emphysema and is often linked to smoking or long-term exposure to pollutants.

Over time, symptoms may worsen and significantly affect the ability to perform daily activities. The disease impacts more than 30 million people in the United States and is the fourth leading cause of death globally, despite the possibility of alleviating its severity through appropriate treatment and lifestyle changes.

The study followed a group of participants, all of whom were former smokers, where their diets and respiratory symptoms were assessed, along with tests for lung function and clinical examinations, at the beginning of the study, then after three months, and again after six months.

The consumption of "isoflavone" compounds, which are plant-based compounds found abundantly in legumes and soy products, was measured and compared to the level of respiratory symptoms among participants.

Legumes include varieties such as lentils, broad beans, chickpeas, and beans, which are important sources of protein, fiber, and minerals. Soy products include soybeans and derivatives such as tofu and soy milk, which are rich in nutrients.

Decrease in Cough

The results showed that individuals who consumed higher amounts of "isoflavone" compounds experienced a reduction in the severity of shortness of breath, a decrease in chronic cough, and improved ability to clear mucus, along with an overall improvement in lung health indicators. Analyses also showed a decrease in certain inflammation and oxidative stress markers associated with disease exacerbation.

According to the researchers, these benefits are attributed to the anti-inflammatory properties of "isoflavone" compounds, as they help reduce airway irritation and enhance the body's response, which is a key factor in chronic lung diseases.

The team added that these results suggest that dietary modification could be a simple and effective means to support the treatment of chronic obstructive pulmonary disease, especially since it is a modifiable factor compared to many other factors related to the disease.

However, researchers emphasize that these foods are not a substitute for medical treatment, but rather an adjunct that can improve quality of life and alleviate symptoms.
