You can’t change your genes. But you can program them.
The modern world presents a number of problems for our genes. The world we’ve constructed over the last 50 years is not the environment in which our genetic code evolved. Our genes don’t “expect” historically low magnesium levels in soil, spending all day indoors and all night staring into bright blue lights, earning your keep by sitting on your ass, getting your food delivered to your door, communicating with people primarily through strange scratchings that travel through the air. So when these novel environmental stimuli interact with our genetic code, we get disease and dysfunction.
The genes look bad viewed through a modern prism. They get “associated” with certain devastating health conditions. But really, if you were to restore the dietary, behavioral, and ambient environments under which those genes evolved, those genes wouldn’t look so bad anymore. They might even look great.
This is epigenetics: altering the programming language of your genes without altering the genes themselves.
