Fish Oil & HDL Cholesterol

Many supplements are available to reduce the risks of contracting heart disease. Fish oil is one that helps provide a positive impact on the cholesterol levels. The beneficial HDL cholesterol can be increased with fish oil, through the introduction of omega-3, a polyunsaturated fatty acid.



Types of Cholesterol



Cholesterol is found as a part of a lipoprotein complex that also consists of protein and other lipids. Low-density lipoprotein (LDL) is a complex that contributes to the development of atherosclerosis. This condition occurs when arterial walls are hardened or narrowed by LDL, and it can lead to stroke or cardiovascular disease. High-density lipoproteins (HDL) are helpful in that they scavenge LDL.



Fish Oil and Omeg-3 Fatty Acids



Fish oil is a substance that is full of omega-3 fatty acids. It is easily added into the diet through eating fatty fish or as a supplement. Fish such as sardines, trout, salmon and halibut are known for containing high levels of omega-3 fatty acids. A typical serving of fatty fish provides about 1g of this valuable polyunsaturated fat.



Omega-3 Fatty Acids and HDL



The Cleveland Clinic reports that omega-3 fatty acids may contribute to a higher HDL level in the blood stream. Omega-3 fatty acids also reduce the production of triglycerides in the liver. HDL levels can be reduced by excess triglycerides in the blood.



Recommendations



Guidelines have been created by organizations for the appropriate amounts of omega-3 fatty acids to be used in the diet. Of the three fatty acids found in omega-3, The Mayo Clinic recommends that between 0.8g and 1.1g of a-linolenic acid. The other two are AHA and DHA, and these should be taken at 0.3g and 0.5g according to the World Health Organization.



Considerations



Fish oil may also increase LDL levels, but it is often considered to not be a "true" increase, but only growth in the measurable amount of LDL. IT is also reported that fish oil might alter other lipoproteins and cause LDL levels to appear more elevated than normal.
