The results of this study provide stronger evidence of the role omega-3 fatty acids play in alleviating cardiovascular effects of pollution
Fort Lauderdale, FL (PRWEB) August 13, 2012
It is well documented that exposure to particulate matter in the air can increase cardiovascular disease and related deaths. Just in California, fine particulate air pollution is estimated to cause 9,000 premature deaths per year. In the first study of its kind, omega-3 fatty acids, such as found in Omega XL®, reduced lipid changes in the blood brought on by breathing particulate matter. More indirectly, the study demonstrated that omega-3 fatty acids might relax blood vessels, lowering blood pressure and affecting nervous system signals that control heart rhythm.
To date, no controlled studies have examined the association between air pollution and Heart Rate Variability. Defined as the variation in the time intervals between heartbeats, Heart Rate Variability is a measure of cardiovascular health. Low variability indicates the heart is poorly controlled by the autonomic nervous system – a part of the nervous system that regulates key involuntary functions of the body – and thus the risk of heart disease is increased.
In the study, conducted at the National Health and Environmental Effects Research Laboratory, U.S. Environmental Protection Agency, and published in the journal of Environmental Health Perspectives, 29 healthy middle-aged participants were supplemented in a randomized, double-blind protocol with either an omega-3 supplement or olive oil (placebo) for 4 weeks before sequential chamber exposure to either filtered air or ultra fine particulate matter for two hours.
The researchers found that after exposure to the high levels of particulate air pollution, heart rate variability decreased significantly in the placebo group. In contrast, the subjects taking omega-3s showed little change. Researchers also found that the placebo group showed an immediate increase in two types of lipid levels in the blood -very low-density lipoprotein and triglycerides - after exposure to particulate matter compared to the omega-3 group.
These data identified two ways in which omega-3 fatty acids offered protection against particulate exposure. First, heart rate variability measures differed between the omega-3 and placebo groups. Omega-3s protected against changes to the involuntary nerve controls that regulate the electrical signals guiding how often the heart beats (rhythmia) and how quickly it can recover. Low heart rate variability is associated with death and arrhythmia.
Second, exposure to the air pollution changed blood lipid levels in the placebo group. After pollution exposure, an upsurge in the types of lipids linked to heart disease and atherosclerosis were measured in those taking a placebo but not in those taking omega-3 supplements.
Many people in the world are exposed to particulate air pollution that may be contributing to ill health. The results of this study provide stronger evidence of the role omega-3 fatty acids play in alleviating cardiovascular effects of pollution than other human studies done to date.
