Important other Omegas
There are many types of fatty acids that the human body uses. These polyunsaturated or monounsaturated fatty acids are classified based on where the first double bond is positioned in the chain, position 3 for Omega-3s, position 6 for Omega-6 and so on.
Polyunsaturated fatty acids such as Omega-3s are considered essential and must be consumed through diet or supplementation as humans are unable to produce them at significant levels on their own.
Omega-6 fatty acids like arachidonic acid (ARA) can be found in significant amounts in meat and meat products. Another omega-6 fatty acid, gamma-linoleic acid (GLA), found in oil from Borage or Evening Primrose also has important functions within the body. It is interesting to note that while both Omega-3 and 6 fatty acids are important to the body our dietary choices favor more Omega-6 fatty acids. This imbalance has been suggested as an important factor in human health causing many health organizations to recommend higher Omega-3 consumption.
Omega-7 fatty acids, of which the most common is palmitoleic acid, can be found in Macadamia nuts and sea buckthorn, as well as fish oils. Palmitoleic acid seems to have beneficial effects on satiety and helping to manage hunger.
Omega-9 fatty acids are well known in the Mediterranean diet. Olive oil consists of approximately 70% Oleic acid, an Omega-9 fatty acid. Lesser known is gondonic acid, the main component of jojoba oil.
