Since we now know that telomers play an inescapable role in the aging processes and therefore in maintaining youth or rejuvenation, let's see precisely what their role is.
From birth, every cell in our body contains a nucleus. Each nucleus contains our genetic heritage. This heritage is inscribed in the chromosomes, which are themselves made up of a double branch of DNA, each branch being composed of units called "protein bases". You have to imagine that each strand of DNA contains about 100 million bases. The successive bases resemble the rungs of a spiral ladder. It is at the ends of these strands (at the foot of the ladder) that the telomers are located, which are themselves made up of several protein bases (about 15,000).
From the first moments of embryonic development, the cells (mothers) start to divide and already at this moment the telomeres start to shorten.
At different rates, all cells in all tissues divide throughout life. With each cell division, the telomers get a little shorter. When the telomers contain only 5000 bases left, old age death occurs.
Like a protective cap, telomeres ensure the integrity and maintenance of the DNA ladder
When this cap becomes too small, it becomes unable to perform this role and the cells that constitute it die in turn.
Many factors can accelerate the shrinkage and death of telomers. Among them are: overweight or obesity, lack of exercise, emotional and psychological stress, smoking, alcoholism, junk food, etc., all factors that generate free radicals. These molecules attack the telomers and cause premature shortening and death of these protective elements.
This phenomenon is far from inevitable. The latest scientific research shows with certainty that we can act on this degenerative process and slow the wear and tear of these telomers.
