A Longevity Lesson

I found an article touting a blood test that can be used to predict longevity.  In actuality, the article was referencing a research study that was done in 2011 and the blood test is looking at microscopic structures on the end of your chromosomes (DNA) called telomeres.  The researchers of this study believe that lifespan can be predicted based upon how long your telomeres are -- the longer they are, the more replications of your DNA you still have left.  While it’s true that these telomeres are a very accurate indicator of how well your DNA is aging, I wouldn’t rush out to get the blood test.

Back in my teaching days, we taught that these telomeres work like photo copies.  Every cell and the DNA inside is constantly being copied or replicated.  Just like when you make a copy of copy of a copy of any document, eventually the quality fades to the point that it’s not functional.  The problem with this study is that it’s too fatalistic -- it suggests that we all have an inborn clock that will time out based on the telomere length we’re born with.  The science of Epigenetics has taught us that numerous lifestyle factors will either shorten or lengthen the lifespan of our chromosomes and their telomeres.  Specifically, a low glycemic diet, rich with fruits and vegetables, regular exercise as well as proper sleep and healthy adaptation to stress will all maintain telomeres for longer periods.  Unfortunately, inflammatory diets high in sugar, grains, and trans-fats, a sedentary lifestyle, and chronic stress will all accelerate the degeneration of these telomeres and our genes alike.  There are literally hundreds of articles that support this lifestyle model of DNA.  One study performed by a Dr. Kent showed that regular chiropractic adjustments reduce the oxidative stress on the cells and enhance repair of the DNA strands.

My point is that this telomere test is situational.  The good news is that no matter what your telomere length is right now, you can enhance longevity by practicing a healthy lifestyle.  Believe it or not, one of the best indicators of how well you are aging is your ability to maintain lean muscle in place of fat.  This is why resistance or strength training in addition to cardiovascular training is critical.  You must challenge your muscles and build strength! Adopting a healthy lifestyle is essential to outsmarting your DNA and living a longer life. Contact us about our wellness program if you are looking for some guidance to get started with this.
