In the strictest sense, there are only two essential fatty acids in human nutrition- alpha-linolenic acid (ALA) and linoleic acid (LA). ALA and LA are required in our diet because our bodies cannot make them. For this reason, ALA and LA are essential nutrients just like calcium, potassium, vitamin C and folate.
The long-chain [...]

Flax seed has been around for quite some time, but it wasn’t until recently that many people realized just how beneficial it was for athletes. Flax seed contains high amounts of alpha linolenic acid (ALA), a type of Omega-3 fatty acid that is converted in the body to hormone-like compounds that play an important role in construction of healthy cell walls, transportation of oxygen to body cells, proper growth of tissues such as muscle, and metabolism of energy for the heart muscle.

Omega 3 (n-3) fatty acids are derived from two main dietary sources including seafood and certain nut and plant oils. As noted earlier, the primary marine-derived omega 3 fatty acids are EPA (C20:5n-3) and DHA (C22:6n-3) which are found in particularly high concentrations in deep water oily fish such as tuna, salmon, mackerel, herring, [...]

As noted, the omega 6 and the omega 3 fatty acid families form different eicosanoids with very different activities. The different eicosanoids compete with one another for enzymes which catalyze the release of the EFA from the cell membranes. An excess of one family of fatty acids can interfere with the metabolism of [...]
