Did you know that fish oil may help fight air pollution-linked changes in heart function? Pollution exposure can affect heart rate variability, a measure of the autonomic nervous system’s regulation of the heart. Heart rate variability is an independent risk factor for heart rhythm problems (arrhythmias), heart attack and sudden death.
A study in the December issue of the American Journal of Respiratory and Critical Care Medicine has found that a daily 2-gram fish oil supplement taken for 6 months prevented a decline in heart rate variability in 26 elderly people aged 81 to 83.
Research says that fish oil supplementation prevented the reduction in heart rate variability associated with the same-day exposure to indoor particulate matter.
