The science of epigenetics is turning what we’ve long held true about biological destiny upside down. Although it remains true that our DNA—our genetic code—provides the blueprint for our physiological makeup, researchers have discovered that there’s something extra controlling our genes—and food and herbs may in fact be the most important factors in our genetic well-being.
That extra “something” controlling our genes is the epigenome, the cellular material that sits on top of the genome (the complete set of genetic material present in a cell or organism). While epigenomes do not alter the genetic code, they direct genes to switch on (becoming active) or off (becoming dormant) through a variety of biological mechanisms. This intriguing finding means that your genetic heritage is not the primary determinant of your health, disease risk, or longevity.
