DNA acetylation – activates genes – Epigenetics.
Activating genes can be great: for instance, yoga and meditation activate genes responsible for reducing oxidative stress (less oxidative stress, less free radicals, healthier and longer life).
Think of the magical resveratrol in red grapes that activates longevity genes.
But let us think about genes we don’t want to activate like cancer genes or the overgrowth of normal cells. Which are believed to be activated by heavy metals, chemicals or toxins.
