Building a Foundation for Healthy Aging: Omega-3s, EPA & DHA

By Michael McBurney

Despite headlines to the contrary, docosahexaenoic acid (DHA) does not cure periodontal disease, or anything else. Omega-3s are nutrients not medicines. However, inadequate DHA intakes have health consequences. Omega-3 fatty acids, eicosapentaenoic acid (EPA) and DHA, are important for brain and cardiovascular health. From conception and throughout life.

Eating 12 ounces of fish weekly during pregnancy is important for the development of baby’s visual and nervous systems. DHA has important structural and functional roles in the brain. DHA is the principal structural fatty acid representing 97% of the omega-3 long-chain polyunsaturated fatty acid in the brain. As discussed earlier, DHA concentrations in cord blood are associated with better infant development and sleep.

DHA requirement may even increase after traumatic brain injury. We need to have a balanced intake of long-chain polyunsaturated fatty acids. Our diet tends to be filled with omega-6 fatty acids and low in omega-3s. We need DHA to nourish and maintain health brain function.

Don’t forget the heart benefits of omega-3 fatty acids. Intervention trials and numerous observational cohort studies from many countries support a primary cardiovascular health benefit for omega-3 fatty acids EPA and DHA. Omega-3 fatty acids help maintain normal triglyceride levels and reduce cardiovascular risk. Because our bodies are not very efficient at synthesizing EPA and DHA, it is important to consume these essential building blocks for a healthy body.

Are you consuming recommended amounts of EPA and DHA?
