Omega 3 fatty acids are one of the four missing nutrient categories which should be added to all processed food diets. In addition, this category is so important, it would be beneficial to add this to raw diets as well. For our carnivores the ideal source is from fish or krill, not flax. Felines do not possess the enzyme necessary to convert flax oil into utilizable fatty acids. The conversion process is very inefficient for canines as well. Body oils of fish are highest in the anti-inflammatory properties of fish oil. Cod liver oil is higher in Vitamin A and D. Be sure to choose a cod liver oil that contains its original, natural A and D, not that which has replaced the natural with synthetic. Be sure any fish oil products have been independently tested to be free of mercury and PCB's. Some fish oils are rancid at the time of packaging. This happens with poor distillation processes. This makes the oil dangerous due to the development of potentially carcinogenic trans fats. In that case, no fish oil is better than rancid fish oil. Always refrigerate open bottles and use them up within three months. Purchase small quantities. Many consider krill a more replenishable source of Omega 3's. Krill are the abundant plankton which are consumed by whales. This is not only an excellent source of DHA and EPA, but also A and D and a potent antioxidant called astaxanthin. These nutrients are prized for their support of healthy skin, joints, brains and hearts. Their anti-inflammatory properties can decrease pruritus (itching), and arthritic discomfort.
