Brain Power: Fish Oil, Omega-3 & omega-6

   If you recall in our previous post on amino acids (Click HERE) we reviewed the importance of three major components in our nutrition and their roles in our body; more specifically that of Amino Acids. In this post we will be looking more closely at Fats and how we can benefit from their value as a supplement.
                So what are Fatty acids? Fatty acids are the building blocks that are the basis of fats and oils and their structure. In today’s society, fats are usually associated with a negative value, however the opposite is true. Our body does need SOME kind of fats, the right kind of course. Those fatty acids that are not made by the body, known as essential fatty acids, need to be supplied though a well-balanced diet.
                Some of the benefits of essential fatty acids include but are not limited to: improving skin and hair, can help lower cholesterol and blood pressure and support prevention of arthritis.  Other benefits include supporting our bodies control and/or aid in prevention of diseases like cardiovascular disease, eczema and psoriasis.
                However a deficit in these fatty acids can prove risky for our bodies. A deficiency of essential fatty acids can lead to: impaired ability to recall information and learning, even children’s formula now contain ARA and DHA, essential fats that promote learning. Essential Fatty Acids are also necessary in the building, rebuilding, and production of new cells.

            Omega-3 & 6
                There are two basic types of categories of Essential Fatty Acids: omega-3 and omega-6. Omega-3 EFAs, are usually found in fresh water fish, fish oil and certain vegetable oils (like canola oil, flaxseed oil, and walnut oil).  Omega-6 EFAs, are primarily found in raw nuts, seeds, legumes, and unsaturated vegetable oil (like borage oil, grape seed oil, primrose oil, sesame and soybean oil).
                (According to an article in Nutritional Healing 5th ed., 2014):
                “…A recent study reported in the British medical journal Lancet has shown that omega-3 fatty acids, which create a more stable arterial plaque, are better for your heart than the omega-6 variety
                They go on to suggest that sacrificing omega-6 consumption for omega-3 may be beneficial. Howeveralways remember to consult your medical practitioner with any questions or health concerns. They also suggest that these oils be consumed in pure liquid or supplement form and to not heat, cook, etc.
            Fish Oil
                Fish oil is a good source of Omega-3 EFAs. Some good sources of fish oil include Salmon, tuna (1 serving per week limit) and sardines, because of their higher fat content compared to other fishes. According to the article (Nutritional Healing 5th Ed., 2014) they point out that that cod liver oil becomes your only source of omega-3, with a high dosage of Vitamin A and D, individuals may be obtaining high dosages amounts of these vitamins, perhaps even overdose.  Individuals with diabetes should care to not take fish oil supplements because of the high risk of fish oil raising their blood pressure.
Always remember to consult your medical practitioner with any questions or health concerns.
