Evidence indicates that aging is coupled to an accumulation of errors in DNA that arise due to strand breakage, DNA replication errors, or dysfunctional DNA repair mechanisms. Naturally occurring background radiation is a pervasive mutagen known to adversely affect DNA. Deuterium oxide is also pervasive and adversely affects DNA.
As a consequence and over time, through the mechanism of increased hydrogen bonding strength, deuterium may disrupt DNA repair enzymes and slow the rate of DNA replication, exposing it to a greater chance of corruption. The maximum lifespan that an organism can achieve is tied to its DNA. DNA is damaged by free radicals produced by radiation, mutagens, and normal metabolic processes.
Deuterium depleted water (DDW) does not change its chemical composition when digested and has a direct effect at the cellular level. Consumption of DDW can conceivably protect DNA from damage and assist DNA repair mechanisms, but it does not directly repair DNA.
It remains undetermined, given present scientific knowledge, whether DDW consumption will “rejuvenate” the body, but it may become a new therapeutic approach or intervention that may assist in protecting cells and tissues of the body, enabling them to function more efficiently.
It is the author’s hope that future studies comparing deuterium in the drinking waters of inhabited and developed environments versus that of lesser developed and sparsely populated locations will elucidate a mechanism for DNA damage and its prevention or reversal
