Fish oil is extracted from the tissues of oily fishes and is often recommended as part of a healthy diet program. Many nutritionists recommend that we eat fish at least once a week. However, emphasis must be placed on the importance of avoiding fish that contain certain harmful contaminants. Predatory fish, such as sharks, have unhealthy substances in their body which can accumulate due to the fish's different predatory lifestyle.
It is thought that fish oil has many health benefits which become a major problem to many individuals who take too much fish oil which leads to serious complications. Daily intake of fish oil can be beneficial for patients suffering from
coronary heart disease as it helps regulate cholesterol. Fish oil is also recommended to prevent cardiovascular diseases and high blood pressure, but high levels of omega-3
fatty acid intake may increase the risk of dangerous side effects, including a stroke. Fish oil is also available in many locations as dietary supplements but purchase requires a doctor's prescription in certain cases. Be sure to read the label and/or instructions carefully before using any medication and/or dietary supplement like fish oil because improper use can have serious effects.
