Fish Oil Myths

The main ingredient in fish oil, omega-3, is an essential fatty acid known to help lower triglycerides as well as reduce the risk of stroke or heart attack in people with cardiovascular disease. You can obtain fish oil either naturally in whole fish or by taking supplements.

Misconceptions

• Myth No. 1: Our bodies don't require omega-3. We must obtain omega-3 by taking a fish oil supplement or by regularly eating fish high in omega-3 such as salmon, mackerel, sardines and whitefish. Our bodies do not produce omega-3 on their own, so if you don't like the taste of fish, take a supplement.

Misconceptions

• Myth No. 2: Environmental contaminants in fish are dangerous to our health. Actually, the health benefits of fish outweigh the risks. Mercury from fish consumption alone is rarely harmful and only if consumed in extremely high amounts. For example, a person who eats sashimi (raw fish) every day may take in a potentially dangerous level of mercury. If you are concerned about consuming too much mercury, limit your intake of shark, swordfish, king mackerel and tilefish.

Misconceptions

• Myth No. 3: Fish oil supplements taste horrible and cause bad breath. While fish oil in liquid form may taste a bit "fishy," it is also available in capsules that will not contribute to bad breath.

Considerations

• The amount of omega-3 each person needs depends on age, sex, weight and a variety of other factors, which you can discuss with a dietitian.

Additional Information

• There is an abundance of myths and incorrect information about nutritional supplements, especially online. Speak with your doctor about any concerns you have before taking a new supplement.
