Optimizing Lung Health: The Benefits of Omega-3 Fatty Acids

They are good for the brain, the nervous and cardiovascular system and the retina… Omega-3! But, according to a new study published in the journal American Journal of Respiratory and Critical Care Medicineomega-3s are also excellent for lung health.

Omega-3 essential fatty acids found in food

“Omega 3 fatty acids constitute a family of essential fatty acids, according to the National Agency for Food, Environmental and Occupational Health Safety (Anses). It includes essential fatty acids, necessary for the development and proper functioning of the human body, but that our body does not know how to manufacture. They must therefore be found in food.

The richest foods are terrestrial plants (nuts, rapeseed or linseed oil, etc.) and fatty fish such as salmon, mackerel, tuna, herring, sardines and anchovies…

“The role of diet on cancer and cardiovascular disease is already well known, but [nous en savons peu sur son] role in chronic lung disease,” says lead author Patricia A. Cassano in a communiqué. This study adds evidence to existing evidence that omega-3 fatty acids, as part of a healthy diet, may also be important for lung health.”

For Healthy Lungs, Consume Omega-3s

During their work, the researchers proceeded in stages, in two stages. First, they conducted an observational study on data from 15,063 Americans collected as part of from another study aimed at measuring the determinants of personalized risk of chronic lung disease. Result of this first step: higher levels of omega-3 fatty acids in the blood are associated with a reduced rate of decline in lung function. And, according to researchers, the most effective omega-3 fatty acid is docosahexaenoic acid (DHA).

The second step was to study data from over 500,000 European participants. Conclusion: Here too, higher levels of omega-3 fatty acids – including DHA – were associated with better lung function.

“We’re starting to turn a corner in nutritional research and are really moving towards precision nutrition for the treatment of lung disease, explains Bonnie K. Patchen, nutritionist and author of the study. In the future, this could translate into individualized dietary recommendations for people at high risk for chronic lung disease.”

The only downside to the study: all the patients included were in good health. Research should soon be conducted for people who are already sick or at risk of developing lung disease.
