One of the most significant aspects of EFA intake is the omega-3 to omega-6 ratio. The conventional “Western” diet includes an excess of omega-6s and a deficiency of omega-3s. Present in nearly all processed and restaurant-cooked foods, recent statistics suggest that vegetablederived omega-6s account for up to 20 percent of calories consumed by the average adult.1 Furthermore, corn-fed beef and pork, one of the primary sources of protein in the western diet, is high in arachidonic acid, an omega-6 more pro-inflammatory than vegetable oils. While they do have their own set of benefits, unlike omega-3s, many omega-6s are pro-inflammatory, can block absorption of omega-3s or decrease efficiency of ALA to EPA conversion, and have even been shown to contribute to the progression of several non-communicable health issues.2 Current evidence suggests that a 1:1 (omega-6 to omega-3) ratio is ideal for optimum health, but the average in industrialized nations is 16:1 and is often much higher.3 Also, of the average 1.6g of omega-3s that the typical American consumes daily, over 1.4g comes from plant-sourced ALA. ALA has been shown to be inferior to EPA and DHA in assisting neurological development and in influencing many markers of health, and is not as easily converted in the body to EPA and DHA as once thought.4 Contemporary study is making it abundantly clear how important it is to get your daily intake of marine-sourced long-chain polyunsaturated fats.
