Omega-3 fats may help prevent deadly lung disease

Researchers from UVA Health and the University of Virginia School of Medicine have uncovered a potential new ally in the fight against pulmonary fibrosis, a deadly lung condition.

In their study, published in the journal CHEST, they explored the relationship between omega-3 fatty acids and the progression of pulmonary fibrosis, along with the delay in lung transplant needs.

Pulmonary fibrosis, characterized by severe lung scarring, impairs the ability to breathe and exchange gases, leading to numerous health issues. Traditionally, lung transplantation has been a critical option for many patients.

The UVA researchers, including John Kim, MD, a pulmonary and critical care expert, focused on omega-3 fatty acids—nutrients found in foods like salmon and flaxseeds—known for their heart-healthy benefits.

Their research involved analyzing anonymized data from more than 300 patients with interstitial lung disease, which can lead to pulmonary fibrosis, from the Pulmonary Fibrosis Foundation Registry and UVA Health and the University of Chicago patient volunteers.

The findings were promising. Higher levels of omega-3 fatty acids in blood plasma correlated with better lung function and longer periods without needing a lung transplant. These positive associations were consistent, regardless of patients’ smoking history or the presence of cardiovascular disease.

Kim and his colleagues suggest that omega-3 fatty acids might play a protective role in lung diseases like pulmonary fibrosis.

Given the established health benefits of omega-3s, including reduced risks of heart disease and certain cancers, this research opens up new possibilities for managing chronic lung diseases.

The study indicates that omega-3 fatty acids could be a targetable risk factor for pulmonary fibrosis, potentially offering a nutritional intervention to improve patient outcomes.

However, further research is needed to understand the specific mechanisms of omega-3s in this context and to identify which omega-3 fatty acids may be most beneficial.

The researchers call for clinical trials and more detailed studies to verify these findings and explore the potential of omega-3 fatty acid supplements or dietary changes in improving the lives of patients with pulmonary fibrosis.

This research marks a significant step in understanding how diet and nutrition might influence the progression of chronic lung diseases and offers hope for new treatment strategies.
