Fish oil helps against heart disease – Omega 3 Fish Oil Benefits

Fish oil helps fight heart disease, the leading cause of death among U.S. population, according to a study by the Agency for Healthcare Research and Quality (AHRQ).

The Agency said that systematic reviews of available literature found evidence that Omega-3 fatty acids present in fish oil can reduce the risk of heart attack or other problems related to diseases of the heart and blood vessels for those already suffering from heart disease.

Although Omega-3 fatty acids do not alter total cholesterol, evidence suggests they can reduce levels of triglycerides, or fat in the blood that contributes to heart disease.

Lowers blood pressure
The experts also found that fish oil helps to slightly decrease blood pressure and risk of coronary artery problems after angioplasty.

It also can increase exercise capacity in patients with arterial obstruction, and even reduce the risk of arrhythmia, particularly in persons convalescing from a heart attack.

“These findings will help the health care professionals and the public understand which benefits of omega-3 fatty acids have been tested scientifically, and concentrate on areas where additional evidence is needed,” said Dr. Carolyn Clancy, director of the AHRQ.

Clancy noted that the translation of scientific evidence into information that can be used to improve health care is the key to the mission of the agency she leads.

The benefits of Omega-3 fatty acids
The test reports of the healthy effects of omega-3 fatty acids are part of a series of studies of so-called Centers of Evidence Based Practice, sponsored by the AHRQ, at the request of the Office of Dietary Supplements of the National Institute of U.S. Health (NIH).

Paul M. Coates, director of the Office of Dietary Supplements, said that “reports on the benefits of fish oil describe positive findings.”

The study emphasizes that the Omega-3 fatty acids do not affect blood sugar during fasting, or glycated hemoglobin in people with diabetes type II.

Apparently, Omega-3 does not affect also insulin levels in plasma or insulin resistance.

Acid found in plants
The alpha-linolenic acid (ALA), a kind of Omega-3 fatty acid from plants such as flaxseed, soybeans and nuts, may help reduce deaths from heart disease, but at a level much lower than fish oil, the experts stressed.

The investigation noted that currently it is not possible to confirm whether Omega-3 contributes to improved respiratory outcomes in children and adults with asthma.

Omega-3 produced apparently mixed effects on people with inflammatory bowel disorders, kidney disease and osteoporosis, while not found any discernible effect on rheumatoid arthritis.
