Fish oil is a rich source of omega-3 fatty acids. Oil is naturally sourced from many kinds of fish, including salmon, mackerel, sturgeon, shark, and mullet. Medical research ascribes many health benefits to omega-3 fatty acids and fish oil. Several studies prove the efficacy of omega-3 fatty acids for cardiovascular health, mental health, immunity, and cancer prevention.
The most obvious health benefit of fish oil proven by research is on cardiovascular health. DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) in fish oil are two components beneficial for cardiac health. Researchers claim that omega-3 fatty acid supplements are effective for treating hypertension and coronary heart disease. Research sources at the American Health Association recommend daily consumption of one gram of fish oil for cardiovascular health. These supplements prevent coronary heart disease as they reduce plaque formation in the arteries. Thus, omega-3 fatty acid supplements help prevent strokes as well. However, some researchers claim that a high dose of fish oil may aggravate bleeding thus raising the risk for a stroke. Therefore, it is advisable to consult your health care provider before starting omega-3 fatty acid supplements.
Fish oil supplements prevent cancers. Cancer is the deadly modern disease attributed to a polluted environment, a skewed diet, and a faulty lifestyle. Many research studies on fish oil have proven its efficacy against prostate, colon, and breast cancers. Researchers believe fish oil supplements may retard the spread of cancer.
Fish oil supplements prevent high cholesterol. These supplements prevent the rise of bad cholesterol in the blood. Research by the National Institute of Health recommends fish oil supplements for treating hypertriglyceridemia, thus reducing the risk for heart disease.
Fish oil supplements are good for the mother and the baby. Neurodevelopment in the fetus is a major benefit. A research study on omega-3 polyunsaturated fatty acids has found them beneficial for fetal brain health. However, the American Heart Association advises pregnant women to avoid fish that may have high mercury content during pregnancy.
Fish oil supplements aid mental health. This oil has also been associated with reduction of suicidal tendency in patients suffering from depression. A very promising double-blind placebo-controlled research study in "European Neuropsychopharmacology" has shown its benefits in depression patients. Some research studies on prisoners have proven fish oil efficient in reducing aggression and assault. Its other benefit in mental health is in schizophrenia, where research claims omega-3 fatty acids help prevent or delay schizophrenia. A Cochrane Collaboration research study done for checking fish oil efficiency in cognitive function in subjects aged over 60 has also given promising results.
Numerous health benefits make inclusion of omega-3 fatty acid supplements in the daily diet a good decision.
