Epigenetics is the study of how cells control a human body’s DNA programming. While DNA provides the codes for making body parts and activating muscles and behaviors, it does nothing without epigenetic inputs; those inputs put DNA into action. They also control the aging process.
Recent research into epigenetics suggests that aging may be delayed or even reduced through diet and lifestyle changes. This is because of biological process known as “DNA methylation” in which methyl molecules attached to the DNA determine whether genes are turned off or on (expressed), and to what extent.
“While it is true that DNA methylation has a ton of power over your health and well-being, you have tremendous influence over it,” says Dr. Kara Fitzgerald in Younger You: Reduce Your Bio Age and Live Longer, Better. "The choices you make every day — what you eat, when you go to be, how stressed you are, how much you move, how much loving touch you engage in — can all negatively or positively influence how and where those methyl groups are places, and therefore how your genes are expressed.”
