Omega 3's are monounsaturated fatty acids found in fatty fish, nuts and seeds. They are invaluable to good health.
Omega 7's are much harder to obtain but they can be made by the body.
Omega 7's are also monounsaturated fatty acids. They have one doube bond located at the number 7 position while Omega 3s have theirs at carbon number 3.
Omega 7's are classifies as non essential because they can be made by the body. This in no way lowers there importance.
Omega 7's can be found in a few foods like cold-water fish, macadamia nuts, and a fruit called sea buckthorn (Hippophae rhamnoides).
Berries from the plant are the best source for Omega 7 fatty acids.
Sea Buckthorn is the richest plant source of these fatty acids and offers other benefits than Macadamia nuts.
Sea buckthorn’s conatins a library of fatty acids, including the Omega 3, 6, and 7s as well as vitamins, minerals, and antioxidants.
Omega 7 fatty acids have drawn a great deal of attention due to the health benefits attributed to palmitoleic acid.
Palmitoleic acid, or (Z)-9-hexadecenoic acid, is an omega-7 monounsaturated fatty acid.
It has chemical formula CH3(CH2)5CH=CH(CH2)7COOH, a common constituent of adipose tissue.
Palmitoleic acid is present in all tissues but is found in higher concentrations in the liver. It is biosynthesized from palmitic acid by the action of the enzyme delta-9 desaturase.
Its considered a beneficial fatty acid because it increases insulin sensitivity by suppressing inflammation.
It is also believed to inhibit the destruction of insulin-secreting pancreatic beta cells.
Palmitoleic acid reduces inflammation by lowering C-reactive protein levels.
When given palmitoleic acid, patients were able to reduce their cholesterol, triglycerides and even body weight.
This is due to the improved insulin response that accompanies improved receptor binding.
This lowers the risk of developing diabetes and obesity.
Sea Buckthorn contains up to 29% palmitoleic acid
Potential biological effects
"In an analysis of numerous fatty acids, palmitoleate was shown to possibly influence fatty liver deposition/production, insulin action, palmitate, and fatty acid synthase, leading to proposal of a new term, "lipokine," having hormone-like effects.
As one such effect may include altered insulin sensitivity, palmitoleic acid (C16:1 n-7) was shown in diabetic mice to attenuate hyperglycemia and hypertriglyceridemia by increasing insulin sensitivity, in part owing to suppression of pro-inflammatory gene expressions and improving hepatic lipid metabolism. Contrary results have been reported, indicating association with lower insulin resistance, presence of atherogenic dyslipidemia, and development of diabetes.[6
The best vegetarian or plant source of Omega 7 fatty acids is sea buckthorn berries. They are the richest plant source of Omega 7 and contain many other health promoting nutrients. Sea buckthorn is an emerging super fruit that has found placement on the Dr. Oz show several times over the last few years. The fruit’s oil is being used by manufacturers of nutritional supplements and especially skin care products because of it’s high content of Omega 7."
