Fish oil lowers LDL & triglyceride levels, confirm new study

Experts recommend daily dose of fish oil in any form, for regulating cholesterol levels in the body, as they contain high Omega-3 fatty acid content that helps in cholesterol regulation.

The scientists at Columbia University Medical Center have proven this fact, yet again. The Director at Columbia Institute of Human Nutrition, Dr. Richard Deckelbaum, says that a diet rich in fish oils can prevent fat accumulation in the aorta, the main artery leaving the heart.

Fish oil helps by blocking cholesterol build-up in the arteries, due to the presence of high levels of Omega-3 fatty acids. These Omega-3 fatty acids also lower triglyceride levels, and inhibit entry of LDL (low density lipoprotein or bad cholesterol) into the arteries, and hence, much lower levels of cholesterol gets collected in these vessels. The scientists attribute this fact to the ability of fatty acids to considerably decrease lipoprotein lipase, a molecule that traps LDL in the arterial wall.

However, scientists believe that the source of fish oil should preferably from the body of fish, and not the liver. This is because liver and liver products of fish contain active forms of Vitamin A, apart from Omega-3, which if present at high levels could be dangerous.

However, consuming fish oil directly from its source, by eating sardines, salmon, tuna and other so-called cold water fish seems to protect against clogged arteries.

The research tem feels that their finding may help in a better understanding of benefits of omega-3 fatty acids on hearth health.

Besides regulating cholesterol, fish oil helps by preventing mental illness and delaying onset of illness associated with age, and its anti-inflammatory properties.

To derive these health benefits, people can either increase fish intake or use supplements containing long-chainĀ fatty acids DHA and EPA, usually found in cold water fish, Dr. Deckelbaum concludes.


  1. I like to know Re. green walnuts and green leves of walnuts and
    Green WALNUTS as PER Medical Health.WAT ARE ADVANTAGE

  2. i’m agree about the statement “Fish oil helps by blocking cholesterol build-up in the arteries, due to the presence of high levels of Omega-3 fatty acids.”

  3. I have read about this else where too. But for Vegetarian Indians what would be the replacement of this? One i can think off is the 7 seas cod liver oil but that is a liver based oil.Can any one suggest more products?

  4. To Muthukumar,
    You may have learned this already, but a vegetarian source would be FLAX OIL. It also has Omega 3 in it like fish oils. I’ve been taking it for 5 yrs–2 tablespoons a day, yes tablespoons, not teaspoons. You couldn’t pay me to stop taking it. Noticed a change the first morning I took it–a decrease in appetite/balancing my blood sugar. After 6 months, it “fixed” the arthritis in my back. It’s one of the best inflammation busters in the world. After 2-3 yrs of taking it, my cholesterol fell down from 203 to 157!! Other friends have reported other great benefits. It seems to go where your body needs it and is deficient.
