The roles of EPA in health – Part I – Inflammation


Inflammation is the response of our immune system to infection or injury. When something harmful affects a part of our body, the immune system acts to remove it and begin the healing process. Inflammation is a sign that the body is trying to heal itself. Infections, wounds and any damage to tissue would never health without inflammation, but excessive or inappropriate inflammatory responses contribute to some acute diseases (e.g.: acute bronchitis, acute appendicitis, acute dermatitis, acute sinusitis, etc.) and chronic diseases (e.g.: asthma, atherosclerosis, Crohn’s disease, chronic sinusitis, periodontitis, rheumatoid arthritis, some cancers, etc.). Inflammation underlies many common diseases and needs to be well regulated.

It has been proved that dietary supplementation with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) has beneficial effects on these diseases. EPA and DHA are converted to resolvins in the course of acute inflammation and resolution. Resolvins regulate immune cell functions and have potent anti-inflammatory actions. These actions may be the reasons for the beneficial impact of omega-3 polyunsaturated fatty acids in health and disease.
