Omega 3's have been in the news lately, because a new study shows that having sufficient Omega 3's has anti-aging properties. These anti aging properties are on a cellular level.
You may remember this blog's reference to an article that discussed Telomeres. Telomeres are structures at the end of chromosomes. They are involved in
the stability and replication of the chromosomes and are being recognized as markers of biological aging. Various things will shorten Telomeres. Genetics, exposure to certain chemicals and environmental stressors can
shorten the length of telomeres.
While the article I referenced discussed exercise's effect on Telomeres, more recently the Journal of the American Medical Association (JAMA) published an article that indicates omega-3s slow down the shortening of telomeres -- also indicating that omega-3 fatty acids may protect against aging on a cellular level.
The sources of Omega-3 fatty acids are varied. Most people look to fish to supply Omega-3's, but over-consumption of fish may have other negative health effects, including exposure to mercury.
Many of you who know me know I am a vegetarian, so I began to look for non-animal sources of Omega-3 and there are plenty. Non-animal sources of Omega-3's include:
Walnuts; flaxseeds; flaxseed oil; hemp seeds (hulled); rapeseed oil; macadamia nuts; brazil nuts; hickory nuts; almonds; spinach; spirulina; wheat germ; peanuts; pumpkin seeds,soybeans, and olive oil. Generally oils should not be heated if you desire the benefits of Omega-3, because heating can break it down.
So, whether through fish or other sources, and in addition to exercise, having a good source of Omega-3 essential fatty acids in your diet may lead to a healthier life.
