Pollution exposure can cause heart rate variability to decline, which is a risk factor for problems including cardiac arrhythmia and heart attack. A new study indicates that fish oil may help counter air pollution-related changes in heart function.
Fish Oil Vs. Soy Oil
Residents of a nursing home took either a daily two-gram fish oil supplement or soy oil supplements for six months. Those who took the fish oil did not experience any decline in heart rate variability.
In contrast, those who took the soy oil experienced only "marginal, nonsignificant" benefits.
Prevents Arrhythmia and Sudden Death
The omega-3 polyunsaturated fatty acids found in fish oil could, therefore, act as a preventive measure against arrhythmia and sudden death, especially among those exposed to ambient air pollution.
With all the wonderful things omega-3 fats can do to help you
I wasn't at all surprised to learn it may also protect your heart from exposure to pollution.
There is very little doubt in my mind that omega-3 fats are the single most important nutritional deficiency in the United States. There would be a massive improvement in our health if more people started consuming more of this vitally important animal fat.
There is quite a bit of confusion regarding omega-3 fats though and many people believe that flax oil is superior to fish oils. Unfortunately flax oil is a shorter chain omega-3 fat called ALA. Your body must take it through two major conversions before it becomes the important DHA omega-3 fat that provides most all of the benefits of omega-3 fats.
Unfortunately most people have a serious impairment of the enzyme (delta-6 desaturase) that converts the ALA to DHA. This is one of the primary reasons why I promote fish and cod liver oil so strongly.
While we all need ALA, I believe it is best obtained from organic freshly ground flax seeds and only as a supplement to, never as a replacement for fish or cod liver oil.
There is even suggestion that those that use flax oil instead of fish oil will actually worsen their health problems.
Krill oil is one of the few supplements I regularly take.
