Good Sources of Fish Oil

Fish oil is an excellent source of two types of omega-3 fatty acids, EPA and DHA. According to the American Heart Association, omega-3 fatty acids are an essential part of any diet and are especially beneficial to those at risk of cardiovascular disease. Fatty fish, such as herring, mackerel, salmon, albacore tuna and sardines are great sources of fish oil and should be eaten two or more times each week. Fish oil is also available in supplement form for those who do not wish to eat fish or are on a restricted diet.

Significance

• Typical American diets are often deficient in omega-3 fatty acids, which makes fish oil an important part of a balanced diet.

Identification

• The best dietary sources of fish oil are wild, cold-water fish, such as salmon, cod, anchovies and tuna, and some stores have begun marking these products with heart healthy symbols to alert customers to their benefits.

Types

• Three main types of fish oil are available in supplement form: pharmaceutical grade oil (which is generally free of contaminants and easily tolerated), health food grade oil and cod liver oil, a lower quality oil that may contain excessive levels of vitamin A.

Benefits

• The benefits of fish oil stem from its high amounts of omega-3 fatty acids, which have been shown to decrease the risk of cardiovascular disease, some mental illnesses, and neurological disorders.

Considerations

• When taken in high doses for long periods of time, fish oil may thin the blood, resulting in increased bleeding and a higher rate of stroke in some people.
