Genomic instability
Protecting the integrity of your genetic blueprint.
Every day our DNA takes tens of thousands of hits: radiation, toxins, free radicals, replication errors. Our cells have remarkable repair machinery, but its efficiency declines with age.
Unrepaired damage accumulates into mutations, cellular dysfunction and, eventually, cancer. This is the first of the nine hallmarks of aging: the one that hits the source code itself.
What this pillar covers
Sources of damage
Tobacco, UV, pollutants, endocrine disruptors, heavy metals, microplastics: identifying what actually damages DNA day to day.
Repair systems
How the body repairs lesions, why these systems run out of steam, and the cofactors that support them (zinc, magnesium, NAD+).
Antioxidant defenses
Glutathione, selenium, carotenoids, polyphenols: the internal shield against oxidative stress and how to put it to work.
Mutations and cancer
From a single lesion to an inherited mutation: understanding the chain that links genomic instability to age-related disease.
Why it matters
DNA is the blueprint for every cell. When the blueprint degrades, everything downstream degrades with it: badly built proteins, cells that lose control, tissues that lose function. Genomic instability sits upstream of almost everything else.
The good news is that this hallmark is largely within our control. Cutting exposure to mutagens and supporting repair through food, sleep and physical activity genuinely changes the trajectory.
You do not choose the genes you inherit. You do influence, every single day, how fast they get damaged.
Where to start
Reduce exposure
Tobacco, excess alcohol, unprotected UV, heated plastic containers: remove the best-documented sources first.
Feed the repair
Colorful vegetables, cruciferous greens, zinc, magnesium, selenium: the cofactors without which repair enzymes simply do not work.
Protect the night
DNA repair is at its most active during deep sleep. Cutting your nights short means cutting repair short.
