DNA analysis can tell us how fast our body goes through the aging process. American and Spanish researchers believe that very soon, this analysis will be included in the broad practice.
We often draw attention to the fact that some people and manages to look 50 years 30 and some 25 have the impression of forty. Of course, lifestyle, physical activity and diet play an important role in the issue aging . But equally important, and have internal factors, such as DNA.
A simple blood test, based on which the experts will be able to calculate the length telomere (end portions of chromosomes) in the DNA, is capable of a high degree of certainty tell how fast we age. Length telomere - A key predictor of processes aging . That is the conclusion reached by researchers from the US and Spain.
"If we know whether the length telomere our chronological age, it will give us an overall picture of the state of health, - the head of the research team, Dr. Maria Blasco from the Spanish National Cancer Research Centre. - Determination of physiological age, in turn, can help detect the disease before its occurrence ".
Telomeres are located at the ends of chromosomes. Many scientists consider them to be a marker of biological aging, a sort of "molecular" clock that is ticking survival cell, as well as an indicator, and overall health. Research shows strong correlation between telomere length and style of life. People exposed to stress, the shortest telomere length.
