Anti aging properties of omega-3 fatty acids

images (4)There are a lot of myths around fish oil supplements rich in omega-3 fatty acids. Several days before yellow newspapers tried to tell that omega-3 fatty acids are useless and even harmful. Really reckless comments. But scientists know the trueth: PUFA regulate cholesterol metabolism (antisclerotic factor), reduce blood clotting and
vascular permeability. The protective function – increases resistance to infections, toxicants, excess of UV (antioxidants). Plastic function – are part of the walls of blood vessels and nerve myelin.
Taking enough of these supplements appears to have enormous health benefits — including dramatic anti-aging effects.

Now, a new study by Ohio State University researchers found that overweight but healthy middle-aged and older adults who took a substantial amount of omega-3 supplements regularly for four months altered a ratio of their fatty acid consumption in a way that boosted preservation of tiny DNA segments in their white blood cells.
The Ohio State scientists found that lengthening of telomeres in immune system cells was more prevalent in people who substantially improved the ratio of PUFA in diet. What’s more, the substantial and regular supplementation also reduced oxidative stress, known to be caused by excessive free radicals in the blood, by about 15 percent compared to the oxidative stress measured in a control group of research subjects who received placebos instead of real supplements.

In yet another finding from this study, Kiecolt-Glaser’s research team reported that omega-3 fatty acid supplements lowered inflammation in this same group of adults. This blows the assertion that fish oil has no heart benefits out of the water.

Inflammation is the main part of many deseases, so any natural substance which has anti-inflamation effect could be useful for older people. It is also known that people with those diagnosis as chronic stress could have much more benefits from PUFA than others.

The scientists also found that decreases in an inflammatory marker in the blood called interleukin-6 (IL-6) in the people taking omega-3 supplements were associated with telomere lengthening. In their earlier paper on omega-3s and inflammation, the same researchers had already reported that omega-3 supplements lowered IL-6 by 10 to 12 percent, depending on the dose. By comparison, those taking a placebo saw an overall 36 percent increase in inflammation-linked IL-6 by the end of the study.
The researchers concluded that this combination of powerful and healthy effects suggests that taking omega-3 supplements could represent a rare, single nutritional intervention that has potential to provide extraordinary health benefits. Specifically, taking these supplements regularly may lower the risk for a host of diseases associated with aging, including coronary heart disease, Type 2 diabetes, arthritis and even mind-robbing Alzheimer’s disease.
