The reason: many farms use crowded pens where salmon are easily infected with lice, may be treated with antibiotics and can spread disease to wild fish (one reason Alaska has banned salmon farms). In addition, it can take as much as three pounds of wild fish (and fishmeal) to raise one pound of salmon.

Servings per Week. The American Heart Association recommends eating fatty fish, such as salmon, at least two times per week. The recommended serving size of fish is 3.5 ounces cooked or 3/4 cup of fish flaked. To reap the most health benefits from salmon, prepare it by baking, steaming or grilling.

Coastal and farmed salmon, depending on the fish and meal they are fed, may have higher levels. The Environmental Defense Fund lists farmed Atlantic salmon as an “Eco-Worst” choice and recommends people eat no more than two servings a month due to high PCB levels.

Plus, due to their feed, farmed salmon contain significantly higher levels of PCBs than wild salmon, prompting the Environmental Defense Fund to warn against feeding kids more than one portion each month. This Lemon Grilled Dill Salmon recipe is a no-fail fish dish for the family. Unlike certain types of farmed fish, freshwater rainbow trout is a great choice for dinner because it’s raised in an ecologically responsible way, is replete with B vitamins, and has a soft texture and full flavor that kids naturally like.

Although salmon contains mercury, it is at a low level. Fresh or frozen salmon is generally low in mercury with a measurement of 0.01 parts per million mean mercury concentration in a 3-ounce serving. Cook your salmon fully before eating it to minimize contaminants. Buy wild salmon to minimize the mercury content.

Eating two meals per week of fatty fish, such as salmon, can reduce the risk of fatal heart disease by 40%. The dangers of eating salmon, meanwhile, are unclear, largely theoretical, and based on studies in animals. The risks would appear to be much smaller than that of developing heart disease.

PCBs get into wild salmon from the other fish they eat and into farmed salmon from their feed (which contains many of these same fish). The FDA has set the safe upper limit for PCBs at 2000 parts per billion (ppb). Farmed salmon averages 27 ppb, well below that limit.

Seasoning on sockeye salmon filets. Sockeye is one of the five main species of Pacific salmon and is generally a wild-caught fish. All salmon are good sources of protein, vitamin B-6, vitamin B-12, niacin, riboflavin, calcium and selenium, which is a trace mineral that helps detoxify mercury. Salmon is an excellent source of vitamin D, found naturally in very few foods and an excellent source of omega-3 fatty acids.

My doctor probably is, too: the new U.S. Dietary Guidelines recommend Americans eat two servings of fish a week. There are so many different types of salmon, which is loaded with heart-healthy, brain-boosting omega-3 fats, and ways to serve them that it would be hard for me to get bored with this fish.
