Fish
There are actually three main types of omega-3 fatty acids: eicosapentaenoic acid (EPA), alpha-linolenic acid (ALA), and docosahexaenoic acid (DHA). The first two, EPA and DHA, are the ones that reduce inflammation, and they can be found in fatty fish like mackerel, salmon, herring, and tuna. You can also get them from supplements.
However, Dr. Devereaux recommends consuming seafood rather than taking fish oil pills. In other words, it’s best to go natural! She also added that following the Mediterranean diet is the best way to get enough omega-3 fatty acids.
Still, you should watch your intake… No matter how good omega-3 fatty acids may be for your lungs and overall health, people with COPD, for example, may not be able to digest large amounts.
