New Findings About Omega-3

New Findings About Omega-3

Omega-3 fatty acids are polyunsaturated fatty acids that are considered essential because they cannot be synthesized by the human body. Dietary sources of omega-3 fatty acids include plants (particularly flax, canola, walnuts and hemp) and fish (particularly ocean fish such as sardines, anchovies, salmon and mackerel). Plants contain the parent omega-3, alpha-linolenic acid (ALA), which can be converted into eicosapentanoic acid (EPA) and docosahexanoic acid (DHA).1

Dietary fish and fish oil supplements are a direct source of EPA and DHA. The influence of ALA, EPA and DHA in human health has been the subject of intense research over the last three decades. Although best known for cardiovascular benefits, new findings indicate that the influence of omega-3 fatty acids in mental health, particularly EPA, may currently be underestimated. Epidemiological, experimental and new clinical studies have all shown a strong connection between omega-3 fatty acids, or a lack thereof, and major depression.

These exciting new findings are not entirely surprising when one considers that the brain itself is 60 percent fat and that one-third of all fatty acids are of the polyunsaturated variety.2,3 As discussed below, the current research highlights the critical role of these fatty acids in the central nervous system (CNS)
