The best sources of Omega-3 fatty acids include flax seeds or oil, walnuts and walnut oil, some types of algae, krill oil, and fatty coldwater fish, particularly wild salmon. Docosahexaenoic acid (DHA), a type of Omega-3 fatty acid, makes up a large part of the lining of brain cells, helps to keep the cellular lining flexible enough to allow memory messages to pass between cells, promotes nerve transmission throughout the central nervous system, and protects the energy centers of the cells, called “mitochondria,” from damage.
Fish that contain high amounts of this Omega-3 fatty acid include mackerel, sardines, albacore tuna, salmon, lake trout, and herring. But be aware, some of these fish have become contaminated with mercury and, as you just learned in chapter two, some research links mercury to the development of Alzheimer’s disease. So, it is important to avoid fish that consistently shows up high on the mercury radar, including predatory fish like swordfish and shark, as well as sea bass, northern pike, tuna, walleye, and largemouth bass. Salmon raised in fish farms also frequently shows up with high amounts of mercury, not to mention that farmed salmon often contains antibiotic residues and lower levels of the important Omega-3 fatty acids.
