Researchers Continue to Find Heart Health Benefits to Omega-3s

Study after study continues to affirm the heart health benefits of omega-3 fatty acids. Experts say that the evidence is fairly conclusive and that anyone who is concerned about their cardiovascular condition should consider adding more of the nutrient to their weekly diet.

The latest in this string of research came from the University of California, San Francisco. Investigators from the school assessed the heart health of a group of patients after a period of five years and examined the level of omega-3 consumption during the study period, according to news station THV.

Their results showed that those who consumed the highest levels of the nutrient had the best heart health. The researchers said that their findings confirm the understanding that omega-3s benefit the cardiovascular system.

“The results of our study do underscore the recommendations of the American Heart Association, that patients with known coronary artery disease should be getting at least one gram a day of omega-3 fish oil,” lead researcher Raimin Farzaneh-Far told the news source.

The findings confirm the results of a 2002 study published in the journal Circulation, which was among the first to assert the heart health benefits of omega-3s.

New findings indicate that omega-3 fatty acids can positively affect ocular health. A research team at the Children’s Hospital in Boston found that omega-3 fatty acids, which can be found in fish oil, promote the growth of healthy blood vessels while simultaneously hindering the development of abnormal vessels.

A previous study of the impact of omega-3, which was conducted by the same researchers, examined the effects of omega-3 on mice. The study revealed that the pathologic vessel growth in the retinas of mice that were fed an omega-3 diet was 50 percent lower than in the mice that were fed diets rich in omega-6. Western diets are more likely to contain omega-6 than omega-3.

In the recent study, the researchers isolated the compounds and enzymes within omega-3 that caused the positive outcome observed in the mice. An examination of the components of omega-3 revealed that its benefits are not inhibited by taking aspirin or non-steroid anti-inflammatory medication.

Lois Smith, a senior researcher and an ophthalmologist at the Children’s Hospital, is also collaborating with the National Eye Institute to study the effects of omega-3 on ocular diseases.
