Many people are unaware of the awesome powers of omega-3 fatty acids. Omega-3 fatty acids are largely found in coldwater fish such as salmon, herring, mackerel and sardines. Flax and flax oil are the most popular botanical sources of omega-3. There are other sources of omega-3 including walnuts, scallops, cauliflower, cabbage, cloves and mustard seeds. Omega-3 fatty acids bring plenty to the table, especially when it comes to your health. It's important to understand why omega-3 fatty acids are so integral to your overall wellness. These polyunsaturated fatty acids found in oily fish and vegetable sources are only available through food. In other words, they can't be processed by the body. A recent study revealed that 99 percent of people in the U.S. don't consume enough omega 3 fatty acids.
