Omega-3 fatty acids have garnered vital curiosity amongst sufferers and clinicians for his or her potential protective health effects, together with lung well being. In our lately printed analysis, my colleagues and I discovered that increased dietary consumption of omega-3 fatty acids is linked to better lung function and longer survival in sufferers with pulmonary fibrosis, a power respiratory illness.

Present in meals resembling fish and nuts and in some dietary supplements, omega-3 fatty acids are polyunsaturated fat which can be important vitamins for individuals.

I am a pulmonologist on the College of Virginia College of Medication, and my analysis crew and I are working to determine threat elements which will contribute to the event of pulmonary fibrosis. On this illness, scarred lung tissue can result in respiratory failure and loss of life.

We examined whether or not increased ranges of DHA and EPA within the blood of sufferers with pulmonary fibrosis in numerous teams of analysis individuals within the U.S. had been linked to illness development. We discovered that sufferers with increased ranges of omega-3 fatty acids of their blood had a slower decline in lung function and longer survival. Notably, these findings endured even after we accounted for different elements resembling age and co-occurring ailments.

Why it issues

At present, there are very few treatments out there for pulmonary fibrosis. Those who do exist have vital uncomfortable side effects. Our findings recommend that rising omega-3 fatty acids in a affected person’s weight-reduction plan might sluggish the development of this devastating illness.

Researchers have investigated the position of diet in lots of different ailments, nevertheless it stays understudied in power lung ailments, together with pulmonary fibrosis. Our research, together with different printed analysis, suggests dietary modifications might affect the trajectory of this illness and enhance a affected person’s capacity to tolerate remedy.


Scarring in lung tissue makes it tougher to breathe.

Moreover, different research utilizing mice have make clear how omega-3 fatty acids might protect against pulmonary fibrosis by regulating the exercise of inflammatory cells and slowing buildup of scar tissue within the lungs.

What nonetheless isn’t recognized

Since we had been in a position to measure omega-3 fatty acid ranges within the blood at just one cut-off date, we couldn’t decide whether or not altering ranges over time correlates with modifications in pulmonary fibrosis.

Crucially, it stays unknown whether or not rising omega-3 fatty acid ranges within the blood could have a significant impact on the lives of sufferers with pulmonary fibrosis. Omega-3 fatty acids within the blood may not straight have an effect on pulmonary fibrosis and should merely mirror more healthy life and diets.
