Importance of Omega3 For Lung Health


New data from a large, comprehensive study in healthy individuals financed by the National Institutes of Health suggests that omega-3 fatty acids, which are rich in fish and fish oil supplements, may be helpful in maintaining lung health. The study offers the greatest evidence of this link to date and emphasises the necessity of adding omega-3 fatty acids in the diet, particularly in light of the fact that many Americans fall short of the recommended amounts. The study's findings were published in the American Journal of Respiratory and Critical Care Medicine. The study was largely funded by the National Heart, Lung, and Blood Institute (NHLBI), a division of National Institute of Health (NIH), Washington DC.

The question of whether nutritional therapies could aid in the fight against lung illness has gained more attention recently. Because of their well-documented anti-inflammatory effects, omega-3 fatty acids have been linked to promising results in earlier studies. However, until recently, there haven't been any reliable investigations of this link.

High Potency Omega 3 Fish Oil Supplement with EPA & DHA

Researchers designed a two-part study to find out more about the relationship between lung function over time and blood levels of omega-3 fatty acids. The NHLBI Pooled Cohorts Study, a sizable collection of NIH-funded studies that aids researchers in understanding the determinants of individual risk for chronic lung disease, was used by the researchers to perform a longitudinal, observational study in the first portion including 15,063 Americans.

The majority of the patients in the trial were in generally good condition at the start and showed no signs of chronic lung disease. They were adults of various races, with an average age of 56, and 55% of them were female. Participants were followed by the researchers for up to 20 years, on average seven years.

Higher blood levels of omega-3 fatty acids were linked to a slower rate of deterioration in lung function, according to the longitudinal study. Docosahexaenoic acid (DHA), an omega-3 fatty acid that is abundant in fatty fish like salmon, tuna, and sardines, showed the highest connections, according to the study. Additionally, DHA is offered as a nutritional supplement.

In the second section, the researchers examined genetic information from a sizable study of European patients from the UK Biobank (more than 500,000 individuals). In order to determine how dietary omega-3 fatty acid levels connected with lung health, researchers looked at specific genetic markers in the blood as an indirect measure, or proxy. The findings revealed that enhanced lung function was linked to higher amounts of omega-3 fatty acids, especially DHA.

The present study does have one drawback: it only involved healthy adults. Researchers are examining blood levels of omega-3 fatty acids in relation to the rate of deterioration in lung function among people with chronic obstructive pulmonary disease or COPD, including heavy smokers, as part of this ongoing project to see if the same beneficial associations are found.

For the time being, the researchers draw attention to the fact that most Americans fall far short of the Dietary Guidelines for Americans' recommendation those adults consume at least two servings of fish per week. Omega-3 fatty acids can also be found in nuts, seeds, plant oils, and fortified meals in addition to fish and fish oil.
