What are Omega-3 & Omega-6 Fatty Acids?
Two basic categories of PUFA’s (poly unsaturated fatty acids) which have received a lot of attention to human nutrition are the Omega 6 and the Omega 3 PUFA’S. Omega 6 PUFA’S are contained in all vegetables oils. Some of Omega 6’s are considered more valuable, such as GLA (gamma linolenic acid, 18:3) found in evening primrose and borange oils. Omega 3’s are found to a limited degree in some plants but are contained in all fish and shellfish. For instance, canola and flax oils contain alpha linolenic acid (18:3). The Omega 3 PUFA’S contained in fish are considered to be five to ten times more powerful in their biological activities than those found in plants.
