Substantial and recent research undertaken to assess the benefits of fish oil indicates that the omega-3 fatty acids in fish oil can prevent cardiovascular disease. It may certainly reduce its risks of it.
In particular, clinical studies have shown that omega-3 fatty acid:
- Lower triglyceride levels.
- Lower blood pressure.
- Reduce the risk of arrhythmias which increase the risk of cardiac arrest.
- Reduce the rate at which atherosclerotic plaque grows.
- Helps to prevent thrombosis (blood clotting in blood vessels).
- Improves endothelial function which supports the growth of new blood cells.
It is significant that fish oil has been found to lower triglyceride levels since high levels of triglycerides have been found to increase the risk of a heart attack.
There is also some indication that it may lower serum cholesterol levels in the human body. Research on this is at its early stages however researchers suggest that at this stage studies indicate that it may be able to increase good cholesterol levels (HDL) and slightly lower bad cholesterol levels (LDL) in some individuals.
Furthermore, it has been found to thin the blood which eases blood flow through the veins. Artery blockages can trigger heart attacks so regular consumption of fish oil can help prevent the clogging.
