This is an excerpt from Dr. Fuhrman’s book Eat For Health.
All fish contain high levels of pollutants–even salmon. But, recent studies showed dangerous chemicals were ten-times higher in farm-raised salmon as compared to wild salmon. If you’re going to eat salmon, wild salmon is a better choice. Since there are growing concerns about the high pollution and artificial colors used in farm-raised salmon, wild salmon has become more desirable and its prices have gone up. However, a 2005 article in The New York Times reported that most fish labeled as wild Pacific or Alaskan salmon is just farm-raised salmon with a lying label. The New York Times tested salmon that was labeled as wild and sold in eight New York City stores and found that most of the fish was farm-raised, not wild.1
They were able to tell the farm-raised from the wild salmon because of the presence of an artificial, pink food dye manufactured by the pharmaceutical company Hoffman-La Roche. The company distributes their trademarked SalmoFan, which is similar to paint store swatches, so fish farmers can choose among various shades to make salmon have a pink-orange color. Salmon in the wild have that color naturally from eating pink crustaceans, but the commercially raised fish have a grey flesh from eating fishmeal. Europeans are suspicious of the dye, which was linked to retinal damage in people when taken as a sunless tanning pill.
Numerous studies also have found surprisingly high levels of PCBs and dioxin in farm-raised salmon. American health officials’ response was that this level of contamination should not stop consumers from eating salmon, but why should you unnecessarily expose yourself to known toxic carcinogens? If you eat salmon, eat only the wild Alaskan variety. If you eat fish once a week, use mostly the lower fat, less contaminated fish, such as tilapia, flounder, scallops, trout, or sole, but I urge you to eat fish infrequently since eating too much can promote heart disease, cancer, and atrial fibrillation.
