Our DNA is coded with a life span.
At the ends of each chromosome lies something called a ‘telomere’.
What exactly is a Telomere, and why should I care?
Telomeres protect chromosomes and prevent them from fusing into rings or binding with other DNA. I like to think of telomeres as being kinda like the little hard plastic ends on the ends of shoelaces, to put it simply. They keep the laces from coming undone.
Telomeres do a similar thing with chromosomes.
When a cell divides, as they do thousands of times every day, strands of DNA get snipped to in the process. The places that are snipped are the telomeres. And the telomeres get shorter and shorter each time.
Eventually the telomere gets too short, and the DNA becomes damaged, putting a halt to the cell’s ability to reproduce. This is where aging occurs.
The rate at which this happens varies among individual people and cells. This is why some people are may be more susceptible to age related disease than others.
How does this affect aging in our bodies?
Scientists can actually determine a cell's age and can estimate how many more times it may replicate by studying the length of the telomeres in a person.
As we age, we look for ways to lengthen our lives, slow aging and keep our cells young.
Recent scientific research shows omega 3 fats can actually slow down the rate at which telomeres on chromosomes shorten. This latest study on omega 3’s and their effect on telomeres that appeared in the Journal of the American Medical Association (JAMA) show that those that had the highest levels of omega 3‘s also had the slowest rates of telomere shortening over 5 years. And the patients with the lowest levels of omega 3’s had fastest rate of telomere shortening.
In other words, those with the highest levels of omega 3 fats, aged the slowest.
This is the first real study that shows a direct connection between a particular nutrient and real anti aging benefits.
Omega 3’s stellar health benefits just keep coming in, including: preventing heart disease, protecting the immune system, weight loss, keeping skin smoother, improving mental health, preventing cancer, and helping fight inflammation.
Telomere length is an important marker of true biological age that accurately predicts illness and lifespan in many areas of health. And, scientists have already shown that rodents live about one-third longer when given a diet enriched with omega 3’s from an animal source.
Obviously you are going to want to load up on omega 3’s.
The best source for well-absorbed omega 3’s fatty acids is from animals, primarily grass fed meat, wild caught fatty fish and pastured eggs. And don’t forget to load up on those antioxidant rich fresh vegetables and fruits.
You can find what foods contain the MOST amounts of quality omega 3 fats in The Fat Burning Kitchen Book.
Till next time,
Stay young, lean and healthy!

Great post. I take an Omega 3 but just learned I need even more. Planning another supplement and more salmon in my diet. 🙂
Thanks for the very important information Cat. Along with fish and eggs, I love avocados as well.
Best eggs are the ‘pastured’ kind–like you get from your local farmer or farmer’s market. Next best kind is organic. Love those eggs!
Very glad to hear a good source of omega 3’s is eggs, since I eat them every day! Great article!
Great info, Cat! And I love how you explained telomeres in a way that’s easy to “digest”. I will definitely be frying up some of our farm eggs for lunch today since I missed out on eggs for breakfast.
Yummy! Where do you get hemp hearts?
Great reminder as to the importance of omega 3’s. Glad I had my hemp hearts with breakfast :). My telomeres feel more robust already!
