It’s the heart of the Primal Blueprint: understanding that our lifestyle factors direct influence the expression of our genetic code. While the DNA itself is set, the structure fixed, that’s hardly the end of the story – our story. How we live – even where we live – holds significant sway over the final picture. And by picture I mean, of course, the picture of our genes’ activity: when proteins are produced (and how much), when or whether certain genes are turned on or off. This activity, researchers are increasingly finding, is key in the development – or avoidance – of any number of conditions like Parkinson’s, Alzheimer’s and cancer. Rather than a predetermined formula simply set in motion in the womb, our genes demonstrate a much more complex, nuanced interplay. The sum of all our daily choices and exposures direct our epigenetic signaling and the course laid out by that ongoing sequence of gene activity. As I’ve said many a time, our original genetic heritage doesn’t design our physiological fate. How we live determines how our genes play out their hand. No doubt a powerful concept, the comprehension can take us by surprise. The quickly expanding field of epigenetics has, indeed, rewritten old school genetics. It’s even ruffled a few feathers here and there, but isn’t that always the case with new breakthroughs?
