After all that hard work you put into learning about Omega Fatty Acids, we're happy to announce that there’s more to learn! Move over Omega, 3, 6, 9, it's Omega 7's time to shine! Known for its heart-healthy benefits – much like the rest of the Omega family – Omega 7 is also known for its other trait; weight loss.

Understanding The Differences Between Omega's

If you've done your homework (or regularly watch Dr. Oz or The Doctors) you're well aware of the health benefits associated with the intake of Omega 3 fatty acids. These fats are sourced from fish, nuts and seeds, as well as plants. Omega 6 fatty acids are also found in many plants, nuts and seeds. Neither Omega 3 nor Omega 6 are produced naturally by your body; therefore, they need to come from some other source, whether food or through supplementation. This is why they are called essential fatty acids. Omega 9’s can be taken in through food, but are considered non-essential, as the body can create it from unsaturated fat.

Key Facts About Omega 7 Fatty Acids

The lesser-known Omega 7, however, is a little bit tricky! Until recently, we didn't know much about Omega-7 fatty acids, and there’s still more to know. Omega 7 is a type of monounsaturated fat. The omega-7 fatty acid that seems to be getting the most attention is palmitoleic acid. This exists naturally in some foods, especially macadamia nuts, and a fruit known as sea buckthorn (this is why Sea buckthorn supplements can claim they contain up to 40% Omega 7's). It is important not to confuse this with Palmitic acid. Palmitic acid is a saturated fat that is on the World Health Organization's list of most damaging fats to our heart. Palmitic acid, abundant in palm oil (but can be found in dairy and meats), has properties that can promote inflammation and can ultimately contribute to heart disease, type 2 diabetes and potentially cognitive decline, over time. Palmitic acid and Palmitoleic acid seem to like hanging out, as they can be found in a lot of the same foods. Their actions in the body, however, could not be any more different.

Health Benefits of Omega-7 Fatty Acids

Studies are suggesting that Palmitoleic acid can reduce high cholesterol and triglyceride levels, as well as lower insulin levels, improve liver function, and promote weight loss. It also seems to have promise as an anti-inflammatory, reducing markers of systemic inflammation. In addition, the intake of Omega 7 fatty acids has been linked to improved bowel regularity and rejuvenation of skin – as it is said to nourish and sustain healthy cells in the digestive tract and skin. In fact, several skin creams on the market contain sea buckthorn and pomegranate seed oil, both high in Omega 7 fatty acids.

Although the final word is still not out on dosage, many studies are focusing on as little as 200 mg daily of palmitoleic acid for noticeable health benefits.

Omega 7 Food Sources

Sea Buckthorn is the richest plant source of Omega 7s available. It can also be found in macadamia oil and pomegranate seed oil, in supplement form. If you are looking for dietary sources of Omega 7 fatty acids, try macadamia nuts, or oily fish, such as salmon, tuna or sardines.
