Within the world of essential fatty acids, a significant amount of interest is reserved for omega 3s and specifically for eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Another omega is gaining prominence called omega-7 (n-7), a palmitoleic acid also known for supporting cardiovascular health. When researchers look at the cardio-value of the Mediterranean diet, they see a complex interaction between multiple fatty acids, including omega-3s, omega-6s, omega-9s and omega-7s. The balance of these fats is crucial for overall wellness and longevity. The focus for this slideshow is palmitoleic, a lesser known but the fifth most commonly abundant fatty acid in the body. This is a review of the most recent research on Omega-7s.
