Helath Benefits of Omega 3 Fatty Acids

Above is a link for Omega 3 fatty acids from Wikipedia.
Omega 3 fatty acids is all the rage these days. So, what is omega 3 fatty acids?

First of all, omega 3 fatty acids are essential fatty acids. That means our body is not capable of making them ourselves. We have to obtain it from our nutrition or supplements.

Below are from the Wikipedia article:

• The benefits of omega 3 fatty acids were discovered in the 1970s by researchers studying the Greenland Eskimos. The Greenland Eskimos consumed large amounts of fat from seafood, but displayed virtually no cardiovascular disease. The high level of omega-3 fatty acids consumed by the Eskimos reduced triglycerides, heart rate, blood pressure, and atherosclerosis.
• On September 8, 2004, the U.S. Food and Drug Administration gave "qualified health claim" status to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) n−3 fatty acids, stating that "supportive but not conclusive research shows that consumption of EPA and DHA [n−3] fatty acids may reduce the risk of coronary heart disease." This updated and modified their health risk advice letter of 2001 (see below). Currently regulatory agencies do not accept that there is sufficient evidence for any of the other suggested benefits of DHA and EPA other than for cardiovascular health, and further claims should be treated with caution.

• The Canadian Government has recognized the important of DHA omega-3 and permits the following biological role claim for DHA: "DHA, an omega-3 fatty acid, supports the normal development of the brain, eyes and nerves."
• The 18 carbon α-linolenic acid has not been shown to have the same cardiovascular benefits as DHA or EPA. Currently there are many products on the market which claim to contain health promoting 'omega 3', but contain only α-linolenic acid (ALA), not EPA or DHA. These products contain mainly higher plant oils and must be converted by the body to create DHA and therefore considered less efficient. DHA and EPA are made by microalgae that live in seawater. These are then consumed by fish and accumulate to high levels in their internal organs. If a person is concerned about mercury and oceanborne contaminants in fish, DHA can be produced directly from microalgae as a vegetarian source.
• Some benefits have been reported in conditions such as rheumatoid arthritis and cardiac arrhythmias.
• Some research suggests that fish oil intake may reduce the risk of ischemic and thrombotic stroke. However, very large amounts may actually increase the risk of hemorrhagic stroke (see below). Lower amounts are not related to this risk, 3 grams of total EPA/DHA daily are considered safe with no increased risk of bleeding involved^[and many studies used substantially higher doses without major side effects (for example: 4.4 grams EPA/2.2 grams DHA in 2003 study).

At Georgia Integrative Medicine, the correct use of omega 3 fatty acids form an important part of the treatment protocol. Most plant sources yield ALA not EPA or DHA. Therefore, the preferred sources are from marine animals including Krill, Anchovies, Sardines, and Salmon. One potential problem taking marine based EPA/DHA is the exposure to heavy metal contaminants which can cause health problems. This can be avoided by buying from a reputable producer of omega 3 fatty acids with molecular distillation and asking to see the certificate of analysis.
