Put fish on your dish--carefully.
So why isn't this an unconditional endorsement for fish? Because some of the fishes with the highest levels of omega-3-fatty acids also deliver a dose of toxic methylmercury, an unfortunate result of industrial pollution of ocean ecosystems. Chronic low-level exposure to mercury can cause neurological problems and cardiovascular problems in adults, as well as significant developmental problems for children and infants. Prenatal exposure can be particularly insidious.
You can have your fish and eat it too, but with caution. Most of the fish available at your local market have significant omega-3-fatty acids. Only a few contain dangerous levels of mercury. Avoid or limit shark, swordfish, king mackerel, and tile-fish. Tuna has lower, but still significant, levels of mercury and should be limited especially for children and pregnant women.
Fish is an important part of a safe and heart healthy lifestyle that prevents or controls high blood pressure. Also include exercise, weight control, a diet high in fruits, vegetables, whole grains and low fat dairy, and moderate alcohol consumption (if you drink).
