Essential Fatty Acids are the type of fats our bodies do not manufacture. It is necessary to obtain these important nutrients from foods we eat. Omega-3 and Omega-6 are the two principle EFAs we need. The primary Omega-3 oils are most accessible from flax seeds, pumpkin seeds and walnuts. Fish oils also contain important Omega-3 oils. The most therapeutic form of Omega-6 oil is found in black currant, borage and evening primrose oils. Our EFA levels affect our behavior, metabolism, brain function, cardiovascular and circulatory system, hormone environment and nutritional profile. New research constantly exposes the many ways these fats are important to our health and well-being.
