Omega-3s & Heart Health: Strong Science Supports Broad Recommendations

Broad medical recommendations, like those now advanced by the American Heart Association (AHA) and National Cholesterol Education Program, come only after extensive research has confirmed usefulness. Multiple types of research are used. Epidemiologic studies compare the difference in disease and diet across groups of people. Experimental studies assess the role of a nutrient or medication in laboratory animals. Clinical studies assess the impact when given to a test group of people. This impact is compared to a “control” group not taking the nutrient or medicine.

Omega-3s from fish oils have been subject to all types of studies, and the benefits associated with cardiovascular health and disease prevention have been consistently shown. As a result, leading medical organizations now recommend Omega-3s from fish oil for cardiovascular health. The recommendations include:

• 500mg/day of Omega-3s from fish oil for adults that have not been diagnosed with coronary artery disease.


• 1000mg (1g)/day for adults that have been shown to have coronary artery disease.


• 3000mg-4000mg (3-4g)/ day for adults with highly elevated triglycerides.

Omega-3s are not associated with reductions in LDL (bad) cholesterol levels. Yet, cholesterol alone is only part of the cause of heart disease. A number of other factors can determine the damage that cholesterol can do. Omega-3s appear to favorably affect these factors including decreased blood pressure, reduced inflammation that leads to plaque formation, and the stabilization of existing plaque.

How significant is the impact on Omega-3s? Studies have indicated as much as a 18-20% reduction in a cardiovascular event such as a heart attack for healthy adult. For those with a history of heart disease, the impact has been shown at least as significant, and perhaps higher.

Omega-3s from fish oil represent an important component of an integrated and comprehensive nutritional approach to cardiovascular health. Other broad recommendations include the consumption of 10+ grams/day of selected soluble fibers such as those from oats, beans, barley and psyllium, 2 grams/day of plant sterols, and diet that restricts saturated fats, trans fats and dietary cholesterol.

Cardiovascular Disease Prevention: Between Healthy Habits and Prescription Medications

With cardiovascular disease the largest cause of death and disability in the United States, the scientific community continues intense investigations into approaches for prevention. In the New England Journal of Medicine, Doctor Mark Hlatky of Stamford University School of Medicine, writes, "The aphorism 'prevention is better than cure' makes perfect sense when applied to healthy habits such as following a sensible diet, maintaining an ideal body weight, exercising regularly, and not smoking. But increasingly, prevention of cardiovascular disease includes drug therapy, particularly statins to lower cholesterol levels."

In this editorial, Dr. Hlatky is reponding to the growing interest in prescribing cholesterol-lowering medications to a much larger segment of the American population---including those with cholesterol levels well below the risk standards established by the National Cholesterol Education Program of the National Institutes of Health. These medications already are the single largest class of drugs sold in the U.S. today, exceeding $30 billion/year.

There is mounting evidence that lowering LDL cholesterol below the NCEP risk-adjusted standards is reducing the incidence of cardiovascular events such as heart attack and strokes. Further, recent studies, notably the JUPITER study published in the New England Journal of Medicine, reinforces the evidence that statin medications not only favorably alters cholesterol levels but also reduce the level of inflammation in the arteries. In addressing inflammation, the medication may reduce a root cause of arterial plaque development.

Yet, what remains lost in the discussions between healthy habits and drug treatment is the positive, therapeutic power of nutrition. Nutritional solutions extends beyond the restriction of saturated fats, trans fats and cholesterol to nutrients that actively improve cholesterol levels and reduce inflammation. For many, these nutritional tools can allow the individual to achieve target cholesterol levels and serve as an effective statin alternative. For others, the nutritional approach offers an opportunity for reductions in the dosages and number of medications required to achieve heart healthy targets.

The tragedy: compared with the funding for pharmaceutical studies, an incredible small amount of money is being spent to advance the nutritional science. With few major studies reporting on the benefits of nutritional cholesterol management, the news media reports on the pharmaceutical studies. The extensive and widely reviewed understanding of the nutritional solution is then overshadowed.
