Fish Oil and Lower LDL

It is not always necessary to take prescription medications to treat conditions you may have. Fish oil has long been used to help reduce cholesterol. Omega-3 and omega-6 fatty acids, the source of healthfulness in fish oil, cannot be made by the body. These two substances can benefit your body by increasing brain function, improving vision and increasing heart health. Your cardiovascular system can be improved by fish oil's influence on cholesterol levels. However, this influence may not necessarily be by lowering LDL cholesterol.

Omega Fatty Acids and Cholesterol

The effect of fish oil on LDL cholesterol, does not necessarily mean a lower level. In a study published in "The Journal of Laboratory and Clinical Medicine" in 2003 by Alain Piolot and colleagues, participants took 6 g of fish oil for eight weeks while cholesterol was monitored. This study found that while fish oil lowered both triglycerides and very low density lipoprotein, or VLDL, LDL cholesterol was left unchanged.

Omega Fatty Acids and LDL

Piolot's research did not account for the effect the omega fatty acids have on the composition of LDL. According to a study published in "The Journal of Lipid Research" by M. Suzukawa and colleagues, omega fatty acids have the ability to increase the size of LDL cholesterol. A larger particle of cholesterol is less susceptible to oxidization. LDL oxidization is a precursor to atherosclerosis, a blockage of the arteries. Therefore, fish oil reduces your risk of developing blood clots. It may be just as important to have LDL that is less susceptible to artery disease.

Recommended Intakes

Omega-3 and omega-6 fatty acids can be in your diet and or taken as a supplement. To get enough omega fatty acids you should eat fish two or three times per week as well as increase your intake of vegetable oils. The best way to eat enough omega fatty acids is to replace lean meats and saturated fats with fish and vegetable oils.

Sources

Fish oil is available in supplement form. However, you should be cautious of supplements because they are not strictly regulated by the Food and Drug Administration. You should always consult your doctor before taking a supplement. Omega-6 fatty acids are found in leafy green vegetables, seeds, nuts, grains and vegetable oils. Omega-3 fatty acids are found naturally in soybeans, flaxseed, nuts and seeds.

Considerations

You should not discount the usefulness of fish oil on the health of your cardiovascular system. Fish oil does not only decrease triglycerides and VLDL cholesterol, but it can also have benefits for your arteries. Fish oil also improves cardiovascular health by helping to reduce blood pressure and clotting.
