Omega-3s May Play a Key Role in Lung Health, Study shows
Updated June 29, 2025
New research indicates that omega-3 fatty acids, abundant in fish and supplements, could be vital for maintaining healthy lungs. The NIH-backed study, published in the American Journal of Respiratory and Critical Care medicine, offers compelling evidence supporting this connection, highlighting the importance of incorporating omega-3s into diets, especially since many Americans fall short of recommended intake.
The research involved two parts. First, a longitudinal study of 15,063 Americans from the NHLBI Pooled Cohorts Study tracked participants for an average of seven years.Results showed that higher blood levels of omega-3 fatty acids correlated with a slower decline in lung function.Docosahexaenoic acid (DHA), an omega-3 found in fish like salmon and tuna, showed the strongest link.
The second part analyzed genetic data from over 500,000 participants in the UK Biobank.Researchers examined genetic markers related to dietary omega-3 levels and thier impact on lung health. Again, higher omega-3 levels, including DHA, were associated with better lung function.
“We know a lot about the role of diet in cancer and cardiovascular diseases, but the role of diet in chronic lung disease is somewhat understudied,” said Patricia A. Cassano, Ph.D., director of the Division of Nutritional Sciences at Cornell University in Ithaca, N.Y. “This study adds to growing evidence that omega-3 fatty acids, which are part of a healthy diet, may be meaningful for lung health too.”
Bonnie K. Patchen, Ph.D., a nutritionist at Cornell, noted the potential for “precision nutrition” in treating lung diseases. She suggested future dietary recommendations could be tailored for individuals at high risk.
James P. Kiley, Ph.D., director of the NHLBI’s Division of Lung Diseases, emphasized the need for further research, stating that the findings “raise interesting questions for future prospective studies about the link between omega-3 fatty acids and lung function.”
What’s next
Researchers are now studying omega-3 fatty acids and lung function decline in people with COPD,including smokers,through the COPDGene study. The USDA recommends at least two servings of fish per week, a target most Americans don’t meet. Besides fish, omega-3 sources include nuts, seeds, plant oils, and fortified foods.
