Prevention
- If you're worried about heart disease, eating one to two servings of fish a week could reduce your risk of dying of a heart attack.
Risks
- Some people are concerned that mercury or other contaminants in fish may outweigh its heart-healthy benefits. However, when it comes to a healthier heart, the benefits of eating fish usually outweigh the possible risks of exposure to contaminants. Find out how to balance these concerns with adding a healthy amount of fish to your diet. If you eat enough fish containing mercury, the …
Benefits
- Fish contain unsaturated fatty acids, which, when substituted for saturated fatty acids such as those in meat, may lower your cholesterol. But the main beneficial nutrient appears to be omega-3 fatty acids in fatty fish. Pregnant women, breast-feeding mothers and children can still get the heart-healthy benefits of fish by eating fish that's typically low in mercury, such as salmon, and li…
Health
- Some fish, such as tilapia and catfish, don't appear to be as heart healthy because they contain higher levels of unhealthy fatty acids. Keep in mind that any fish can be unhealthy depending on how it's prepared. For example, broiling or baking fish is a healthier option than is deep-frying.
Preparation
- For adults, at least two servings of omega-3-rich fish a week are recommended. A serving size is 3.5 ounces (99 grams), or about the size of a deck of cards. Women who are pregnant or plan to become pregnant and young children should limit the amount of fish they eat because they're most susceptible to the potential effects of toxins in fish.
Toxicity
- The risk of getting too much mercury or other contaminants from fish is generally outweighed by the health benefits that omega-3 fatty acids have. The main types of toxins in fish are mercury, dioxins and polychlorinated biphenyls (PCBs). The amount of toxins depends on the type of fish and where it's caught.
Causes
- Mercury occurs naturally in small amounts in the environment. But industrial pollution can produce mercury that accumulates in lakes, rivers and oceans, which turns up in the food fish eat. When fish eat this food, mercury builds up in the bodies of the fish.
Diet
- Large fish that are higher in the food chain such as shark, tilefish, swordfish and king mackerel tend to have higher levels of mercury than do smaller fish. Larger fish eat the smaller fish, gaining higher concentrations of the toxin. The longer a fish lives, the larger it grows and the more mercury it can collect.
