Our rivers and oceans absorb the mercury produced when we drive cars, burn coal to fuel power plants, and incinerate household wastes. They’ve also become toxic waste dumps for many other industrial pollutants, such as PCBs and dioxin. These harmful chemicals are absorbed into algae and plants that are then eaten by fish. The pollutants become more and more concentrated as they travel up the food chain. Once one of the world’s healthiest foods, all wild fish and even some farm-raised varieties are contaminated with disease-promoting chemicals. To reduce your risk of consuming more of these toxins than your body can clear, consume only fish that have been shown to have the lowest levels of mercury.
