I don't know anybody who is not getting older, but I know lots of people who would like to not look and feel old.
Telomeres are tiny caps at the ends of DNA segments. Current thinking is controlling them might be a major breakthrough in aging or as most of us would prefer -- anti-aging world.
Telomeres are caps at the end of chromosomes.
Teleomeres are often explained to the non-science types as being analogous to the plastic cap at the end of a shoelace. If the cap comes off the shoe lace it frays and pieces of it break off.
Each time a cell divides a little bit of its telomere end cap disappears and at some point its effectiveness diminishes and the chromosome becomes frayed sort of like a shoelace will. One solution would seem to be not doing anything that causes cells to replicate more than normal.
Or put another way: Do things that are good to your cell. Such as not doing things that are bad for your cells (smoking).
Cell replication is a normal process. One day soon it may be poven that accelerated aging is tied to the loss of telomeres.
Admittedly that was simplistic
The science of telomeres and the telomerase enzyme is fascinating, but complex. You can get the quick and dirty about the process here. I don't want to write several thousand words to explain it in detail, because that is not helpful to readers in a hurry.
So let me just sum up telomeres by suggesting they may prove to be extremely important in the rate at which we age, and we do not want to do things that affect them negatively, but if we can affect them positively -- that will be cool.
Omega-3 fatty acids (fish oil) and anti-aging via telomere preservation
Scientists have known for awhile that omega-3 fatty acids from food or pills deliver many health benefits, but what about a connection to aging?
A 2012 study from Ohio State University found that most overweight but otherwise healthy study participants who were middle-aged and older and took omega-3 supplements for four months altered the ratio of their fatty acids in a way that helped to preserve telomeres. It’s the first evidence to suggest that a nutritional supplement might actually help make a difference in aging.
Consumer Reports magazine, which many people think is almost Biblical (I don't share that belief). But here is something that Consumer Reports had to say about the preceding.
One more piece of anti-aging news
There is an article published yesterda about Resveratrol on my Fitness Page.
In the past decade Resveratrol has gained strong support from some fitness lifestylers.
If you use Reservatrol or are considering using the supplement, the article contains a link to new piece of research appearing in the Journal of Physiology that might be useful to you.
