Epigenetics | Andrea Nakayama's Field Guide to Functional Nutrition


Let’s talk epigenetics.

Epi- is a prefix taken from the Greek that means “upon, at, by, near, over, on top of, toward, against, among.”

Epigenetics are the factors that bathe our genes and prompt them to express negatively or positively. This contributes to all known dysfunctions.

We’ve all got genes. We know that.

And by now most of us also know that the genes we have don’t dictate our health or lack thereof. Most of us are familiar with the saying “genes load the gun, but environment pulls the trigger”.

Epigenetics are that environment.

And the environment is how we influence the genetic and cellular expressions that manifest as signs, symptoms and disease states. We shift the environment by modifying factors like diet, lifestyle, and biological function (or how the body performs its many jobs).

These habit changes that each and every patient can make—especially with your help and know-how as an allied functional medicine practitioner—result in clinical remedies. When we develop Epigenetic Mastery we have the skills to guide our clients in ways that enable all controllable health factors to be addressed.

And when you help your clients take charge of their internal and external environments, you catapult their health, and your success.

Let’s take a quick lesson from twins to drive the concept of epigenetics home…

Identical twins are said to be genetic carbon copies of one another. And yet, over time, these identical twins shift and change so that their physical expression often becomes distinct. In other words, we can more easily tell one from the other.

While it’s the genes that provide the instructions for the development of the body, it’s the epigenome that interacts with the DNA to provide what might be considered a second set of instructions.

This second set of instructions works to turn on or turn off particular genes by tagging them, thereby influencing the expression, but not the genetic code itself.

Twins start out with not just the same genes, but the same imprinted epigenome (the tags that come with us at birth, that are handed down from our parents—something otherwise known as “antecedents” in Functional Medicine). Yet as aging occurs, the environment of the twins will begin to differ—different relationships, different food choices, different sleep patterns, exposures to viruses, etc. These differences will influence their epigenome—or environment—and therefore their genetic expression and physical manifestation.

Here’s a quick list of factors that you can consider that impact genetic expression:

  • diet
  • nutrition
  • hydration
  • toxic exposures
  • stressors
  • relationships
  • community/support
  • sleep
  • relaxation
  • exercise
  • and more

When you find yourself lost, trying to be a genetic genie, remember that you likely have more of an opportunity to influence gene expression by backing up and considering the epigenome.
