Why Animal-Based Omega-3s are Best

According to an article recent by Joseph Mercola, MD, omega-3 fats of animal origin are critical for heart health. Dr. Mercola believes that maintaining a sufficient level of docosahexaenoic acid (DHA) can be one of the most important nutritional priorities. People need DHA, an omega-3 carbon 22 and ALA (alpha-linolenic acid), an 18-carbon omega-3 fat. Both omega-3 fats of plants and animals are important, but the DHA present in shellfish is the type most associated with heart health and other vital health benefits.

Recent studies indicate that eating fatty fish and other foods rich in omega, including some plant foods can reduce the risk of a fatal heart attack by about ten percent. When taken after a heart attack, omega-3 can significantly improve their chances of long term survival. In one study, heart attack survivors who ingested 1 gram of omega-3 a day for three years reduced their risk of sudden cardiac death by half.

Another placebo-controlled study confirmed that high doses of omega-3 facilitated healing after a heart attack. 360 cardiovascular patients were divided into two groups. The treatment group had four grams of Lovaza, a fish oil omega-3 recipe. The other group received corn oil as placebo. After six months, the treatment group showed a decrease of 5.6 percent in scarring of the heart muscle in good condition. Their hearts were also stronger and more able to pump more blood.

According to a report in Reuters:

Some people are better able to absorb and use fish oil, and those with the greatest increase in the levels of red blood cells omega-3 levels had a reduction of 13 percent in the remaining blood in the left ventricle, compared with a reduction of 6 percent for the group of fish oil in general.

Dr. Mercola adds that all natural forms of omega-3 fatty acids, such as fish oil or krill oil are much better absorbed by the body. Corn oil, which was used in the placebo, is an industrially processed omega-6 fatty GMO known to adversely affect the heart.

There are other ways in which omega-3 animal origin, especially DHA, fats benefit heart health. These include:

Lowering blood pressure
concentrations reduce triglycerides
Improved endothelial function (which helps promote the growth of new blood vessels)
counteract or prevent cardiac arrhythmia
Helping prevent thrombosis (blood clot in a blood vessel)
preventing fat deposits and fibrosis of the inner layer of the arteries
Counteracting inflammation.
