from the truth.
Your genetic makeup certainly plays a
role in everything from height to eye color to
health. But even more important than the
genes in your DNA sequence is which of those
genes get turned on. A gene that isn’t turned
on doesn’t actually do anything. It’s the
intersection of your environmental inputs and
your genetics that is truly relevant to your
health.
Epigenetics is the intersection of your genes
and your environment.
Epigenetics is the study of gene
expression—whether genes turn on or turn
off, and how loudly their information is
expressed. While we are all born with a
certain code, we are also born with switches
that tell that code what to do. Our
environmental input (diet, exercise, air
quality, etc.) activates those switches. Think
