(NaturalNews) As the population of American baby boomers continues to swell, age related afflictions including diabetes, cardiovascular disease and complications such as blindness are growing at a similar pace. The number of people aged 65 or older will double over the next 20 years creating an epidemic of chronic conditions that perpetuate with age. According to the result of a study published in the American Journal of Clinical Nutrition, a diet supplemented with the Omega-3 fatty acid DHA (Docosahexaenoic Acid) can significantly lower the risk of sudden cardiac death, heart disease and visual degeneration leading to blindness.
Another key component in the progression of cardiovascular disease is systemic inflammation that leads to unstable plaque known to rupture and cause a heart attack. Further evidence of the importance of DHA in lowering heart diseases risk is published in the journal Nature Chemical Biology. Researchers found that DHA influences the action of immune system macrophages. Working at the genetic level, DHA is shown to control the release of cellular antioxidants that inhibit the damage caused by excessive and chronic inflammation to the coronary arteries.
DHA is an important tool in the prevention of stroke. Many of the mechanisms that increase incidence of a heart attack also contribute to stroke risk. DHA becomes incorporated into the cell wall structure where it stabilizes existing plaque, making it less likely to break off and cause a stroke. DHA has been shown to help blood flow easier, lower the risk for clotting and reduce blood pressure. High levels of DHA can prevent hardening and thickening of the arteries that result in vascular decay.
The journal Science Translational Medicine reports the result of research that demonstrates how DHA regulated genes that can prevent blindness. DHA is highly concentrated in the retina and can control the abnormal growth of blood vessels in the eye that cause visual degradation. By halting unnecessary growth, DHA regulates vessel formation so that healthy blood vessels form and undesirable ones do not.
Fatty fish such as salmon, mackerel, herring and trout are ideal sources of Omega-3 fats including the DHA fraction. Due to the ever-increasing problem of mercury contamination in fish, supplementation is well advised. Nutrition experts recommend a molecularly distilled, dosage-controlled supplement that supplies 250 to 500 mg of DHA (not EPA and DHA combined, read labels carefully) daily to dramatically lower the risks from heart disease, heart attack, stroke and blindness.
