Each time chromosomes divide and
multiply, instead of losing the DNA that matters, they lose only some of the
telomere’s DNA. With every replication of our DNA, part of the telomere
sequence is chopped off. This is how nature protects the DNA in a chromosome. Basically,
we start to die the day we are conceived: the embryo has about fifteen thousand
base pairs in its telomeres, a newborn human approximately ten thousand base
pairs. With each cell division, a few base pairs are lost, until the critical limit
is reached. In some people this process happens quickly, in others it can take
much longer.
Seldomly, a few telomeres become
longer, thanks to the telomerase activity. The key to immortality is turning
the telomerase gene from off to on.
Nature already does that: it is
NOT impossible. In sperm cells, the enzyme telomerase adds telomere DNA back to
the cells’ telomeres and keeps those telomeres as long as they have always
been. That’s why an eighty year old man can still father children.
Now it should be much clearer how
telomeres and telomerase work.
In an ideal world telomeres would
shorten slowly and we’d live longer: in our sad reality the food is grown in
nutrient-poor soil that contains pesticides and heavy metals from acid rain. Cattle,
chickens and other animals are raised in unsanitary conditions, pumped full of
hormones and antibiotics.
So, the first hint to preserve
your telomeres is to switch to organic food. Although not being perfect is so
much better than regular food.
