Some sources claim that fish oils reduce the risk of heart disease and stroke, but WebMD says there is not any research available to substantiate these assertions. As of 2014, scientists are testing fish oil's effects on Crohn's disease, psoriasis, cancer, depression and asthma. It is best to obtain fish oils from natural sources, such as salmon, tuna, sardines, cod liver and mackeral.

Omega-3 fatty acids can be obtained from additional food sources, including walnuts, flaxseed, soybeans, tofu and canola oil. WebMD explains that the body needs to maintain a healthy ratio between omega-3 and omega-6 fatty acids of 3:1 or 4:1, with omega-3 fats comprising the great majority of amino acids found in the blood. To do this, people should cut down on many unhealthy oils, meats and eggs in an effort to reduce the risk of developing several types of chronic disease. WebMD advises people who rely on prescription blood thinners or take anti-inflammatory pills to avoid mixing the medications with fish oils, as they can increase the risk of bleeding or hemorrhagic stroke.
