Heart Health: According to the American Heart Association (AHA), clinical trials have shown that omega 3 is effective in reducing the incidence of cardiovascular diseases (CVD). Fish oil is a great source of omega 3 and therefore, reduces the risk of heart diseases and heart arrhythmias. It also lowers the level of bad cholesterol (LDL), and increases the level of good cholesterol (HDL). Fish oil prevents the accumulation of triglycerides and further reduces the level of excess triglycerides. Preliminary research has also shown that fish oil can be used to prevent atherosclerosis in coronary patients. Thus, fish oil is effective in preventing strokes and regular usage of fish oil can help avoid sudden cardiac death. As per the American Heart Association, these preliminary findings still need to be confirmed by further detailed research.
Weight Loss: Fish oil has also been popularized as an aid in losing weight. Research conducted by Professor Peter Howe at the University of South Australia has shown that fish oil improves the efficacy of exercise in attempts to reduce weight. Volunteers who were given fish oil in their diet showed greater weight loss as compared to those who did not regularly consume fish oil. Exercise combined with fish oil had a positive effect on body shape and composition of the participating patients.
Improved Immunity: It is believed that regular consumption of fish oil aids in boosting your immune system, thereby enabling you to resist the occurence of common diseases like colds, coughs and the flu. Omega-3 fatty acids present in fish oil bolster the immune system by effecting the activity and amount of cytokines and eicosanoids present in our body. Researchers have also studied the effect of fish meal and fish oil on the immune system of pigs and found that fish oil aided in the growth of the animals. Similar research conducted on mice at Taichung Veterans General Hospital, Taiwan, also gave positive results.
