What Is Epigenetics? How Your Child’s Environment Shapes Their Health More Than Genes
Episode 119, Experience Miracles Podcast | Host: Dr. Tony Ebel, DC, CACCP, Pediatric Chiropractor & Founder of PX Docs | Published: July 1, 2024 | Duration: ~15 min
Key Takeaways
- Epigenetics, the science of how environment influences gene expression, shows that lifestyle, toxin exposure, and stress during critical developmental windows have far more impact on a child’s health than predetermined genetics.
- The dramatic rise in autism, ADHD, anxiety, and autoimmune disorders cannot be explained by genetics alone; human genetic code requires hundreds to thousands of years to shift enough to produce population-level changes in chronic illness rates.
- The Perfect Storm, the combination of fertility and pregnancy stress, birth interventions and trauma, and early toxin exposure, represents the three most significant epigenetic stressors driving chronic childhood conditions today.
- During critical development windows (fertility, pregnancy, early infancy), high stress and toxicity literally alter how a child’s genes are expressed, affecting nervous system development, immune function, and long-term health outcomes.
- Parents have more control than conventional medicine acknowledges: changing the environment, reducing stress, and supporting nervous system function through Neurologically-Focused Chiropractic Care can shift gene expression and support healing.
What Is Epigenetics, and Why Does It Matter for Your Child’s Health?
Epigenetics is the science of how environmental factors influence which genes are activated or suppressed, without changing the underlying genetic code itself. While conventional medicine has long operated under the genetic theory, the idea that conditions like autism, ADHD, and anxiety are largely predetermined by heredity, epigenetics reveals a fundamentally different picture: your child’s genes are not their destiny. The environment they develop in is.
The “epi” in epigenetics literally means “above” or “outside” the genetic code. When children experience high stress, toxin exposure, or physical trauma during critical windows of development, fertility, pregnancy, and early infancy, it can change how their genes express themselves. The nervous system is the key mediator in this process. As researcher Dr. Bruce Lipton explains, “The function of the nervous system is to perceive the environment and coordinate the behavior of all other cells.” The nervous system reads the environment and tells the genome how to respond.
For parents navigating chronic childhood conditions, this is fundamentally empowering news. The rise in autism, ADHD, autoimmune disorders, and anxiety isn’t a genetic lottery, it’s largely a product of an increasingly stressful, toxic environment during the most sensitive periods of development. And what environmental stressors have influenced, targeted intervention can begin to address.
Why the Genetic Theory Doesn’t Add Up [00:00:00 – 00:03:30]
Dr. Tony Ebel, DC, CACCP: Are you tired of being told your child’s health challenges are just genetic and there’s nothing you can do about it? Do they keep blaming genetics and bad luck while offering little to no explanation of the real root cause, then just recommending more and more medication? It’s time for parents to learn the fascinating science behind epigenetics, which clearly shows that your child’s genes are not their predetermined destiny.
The conventional medical system still operates under what’s called the genetic theory, the idea that your health destiny is largely written at birth. If autism is on your family tree, they say autism is in your genes. If ADHD runs in the family, ADHD is predetermined. They dismiss chronic childhood conditions through this lens, and then recommend medications to manage what they claim is genetically inevitable.
The problem is the math doesn’t work. The human genome project attempted to map how many genes we have against how many proteins those genes produce, because proteins create the biological reactions that determine health. The numbers didn’t add up. More importantly, it takes hundreds, really thousands, of years for genetic expression to shift enough from one generation to the next to explain a population-level change. Yet we’ve seen a dramatic meteoric rise in autism and chronic illness within just one to two generations. That rate of change is impossible to explain through genetics alone.
The medical system’s attachment to the genetic theory isn’t purely scientific. They need us to believe in genetic predeterminism because they need us to believe that we need their products and their medications. If your child’s condition is genetic, you’re dependent on pharmaceutical management for life. If it’s environmental, you have agency, and the pharmaceutical model loses its grip.
A Farm Kid, a Genetics Major, and the Moment It Clicked [00:03:30 – 00:07:00]
Dr. Tony Ebel: A little bit of backstory. I’m also a farm kid from Iowa, and I love to keep things simple as well. The farm kid story actually comes into this epigenetics conversation.
I grew up on a farm during the time that genetically modified organisms (GMOs) entered the agricultural marketplace. I was my dad’s right-hand man when we started planting corn that was already genetically modified in a lab so that you could spray pesticides on it, things that would kill humans and other animals. Literally every other living thing in the vicinity. But the corn and soybeans, the food that billions of people now eat, was genetically modified to survive. I grew up during this genetic shift in the agricultural world.
I went into undergrad at Iowa State as a molecular biology and genetics major, and I eventually dropped the genetics major. Because when you run the math on genetics, as the medical field has told us it is, it doesn’t add up. It literally doesn’t math out.
The full throttle irony here is that the medical establishment labels chiropractors and natural health advocates as “unscientific” and “conspiracy theorists”, while continuing to operate on a genetic model that the human genome project began to disprove around 20 years ago. What put it to rest back then still hasn’t filtered through to how conventional medicine treats chronic conditions in kids today.
“It takes literally hundreds, really thousands of years to change our genetic expression from one generation to another enough to explain the dramatic meteoric rise in autism and chronic illness. Whenever you see a condition change that much, it has to be outside environmental epigenetic influences.”
What Epigenetics Actually Means [00:07:00 – 00:09:00]
Dr. Tony Ebel: The “epi” part means environmental influence over our genetic code. What we now know about the way our genetics really play out for our kids and our families is that our environment very much influences the activation and bringing forth of certain genetic presentations.
Therefore, if our kids grow up in a natural, nervous system-regulated, toxin-free, chemical-free, fear-and-anxiety-free environment, because nervous system development does have a lot to do with genetic code, it changes what their genetics actually produce. The science is not one factor or another. It’s an interplay between genetics, the nervous system, and the environment.
The nervous system turns on within the first couple of weeks of fetal development and then coordinates and modulates everything from that point forward: every developmental milestone, gut function, immune function, inflammation response. Everything else from there on after is controlled by the brain and the nervous system.
Here’s the key principle: if there’s a significant amount of stress, fear, anxiety, and toxicity during critical sensitive periods of development, fertility, pregnancy, early infancy, it changes the expression of that child’s genetic code. This is no longer theory. The research base on epigenetics has grown substantially, and the science is clear.

The Perfect Storm: The Three Epigenetic Stressors [00:09:00 – 00:11:00]
Dr. Tony Ebel: The three epigenetic influences that every parent deserves to know about are what we call The Perfect Storm.
First: high-stress fertility and pregnancy journeys. The stress hormones and physiological environment a mother experiences during conception and pregnancy directly shape fetal nervous system development.
Second: birth injuries and interventions, forceps, vacuum extraction, emergency C-section, cord complications, induction, epidural. These represent significant physical and neurological stressors at one of the most critical windows of nervous system formation.
Third: early and cumulative exposure to toxins and medications. The toxic load theory, the idea that the body can only handle so much before its regulatory systems are overwhelmed, fits within the Perfect Storm framework as the third major epigenetic stressor.
These three factors together explain the chronic illness rates we see today. The research backing the Perfect Storm and epigenetic influence has been mounting for 10 to 20 years. The traditional genetic model of disease is being quietly abandoned at the research level, but the clinical system is slow to follow.
“High-stress fertility and pregnancy journeys, birth injuries and interventions, and early exposure to toxins, these are the three epigenetic influences that drive what we call the Perfect Storm.”
The Deck of Cards Analogy [00:11:00 – 00:13:00]
Dr. Tony Ebel: Think of your child’s genetics like a deck of cards. There are four suits, and depending on the hand you’re dealt, certain outcomes become more or less likely. Some families have a deck with more cards in the autoimmune suit, or more in the emotional and mental health suit, ADHD, anxiety, depression, because of generational environmental habits, lifestyle patterns, and stressors passed down through families.
But here’s where the empowerment lives: genetics isn’t a verdict. It’s a set of probabilities. And epigenetics is how you influence which cards get played.
If a child’s parents didn’t exercise, ate poorly, and carried chronic stress and negativity, the environment those choices created is what shapes the next generation. Not just genetically, but epigenetically, through the lived environment that child steps into.
For me personally, heart disease runs in my family. Rather than treating that as a death sentence, I use it as information. If my deck has more heart problem cards in it, I’d better take exceptional care of my lifestyle. If the deck is slightly or somewhat stacked against me, well then I can control which cards I play. I can control which actions and behaviors I take on when it comes to my health and my lifestyle, and which I do not. That’s the real message of epigenetics.
Taking Control: Epigenetics as Empowerment [00:13:00 – 00:15:00]
Dr. Tony Ebel: When you understand epigenetics, you can take it two ways. You can look at the toxic, stressful world we live in and say, “What chance do we have?” Every chance possible. Because we can take this information, about how much control we truly do have over our health and the health of our kids, and use it to reverse challenges we’ve been navigating once we get the right information.
Epigenetics applies in two directions. For families already navigating chronic illness: change the internal and external environment, reduce incoming stressors, support the nervous system through regulation and Neurologically-Focused Chiropractic Care, and the body can begin to repair, restore, and heal. You have to do both, healing from the inside and cleaning up the lifestyle so there’s less stress coming in.
For families already living naturally and proactively: this science confirms that your choices matter. You’re not subject to good luck or bad luck. The lifestyle and environment you create for your children is the single most determining factor in their long-term health outcomes, far more so than the genetic cards they were dealt.
“Our lifestyle and our environment that we choose to put ourselves in is the most by far determining factor as to what we get out of this. And we have control over that.”
This is why epigenetics matters as a foundational concept for parents. It replaces passive acceptance of genetic predeterminism with agency. It reframes chronic illness as the result of addressable environmental stressors rather than an immutable biological sentence. And it points toward a path: clean up the environment, support the nervous system, and work with how the body was designed to function. God bless, be well.
Frequently Asked Questions
What is epigenetics, and how does it affect my child’s health?
Epigenetics is the science of how environmental factors influence which genes are activated or suppressed during development. For children, high stress, toxin exposure, and birth trauma during critical development windows can change how genes express themselves, influencing the risk for conditions like autism, ADHD, anxiety, and autoimmune disorders. Unlike fixed genetics, epigenetic influences can be addressed by changing the environment and supporting nervous system health.
If autism or ADHD runs in my family, does that mean my child is destined to have it?
No, that’s the genetic theory, and the science has moved well past it. Epigenetics shows that genetic predisposition is only one input. The environment during pregnancy, birth, and early childhood plays a significant role in whether those genetic tendencies are ever activated. A family history of ADHD or autism indicates a susceptibility, not a sentence. Choices around stress, nutrition, toxin exposure, and nervous system care directly influence which genetic expressions emerge.
What are the biggest epigenetic stressors for children?
According to Dr. Tony Ebel’s Perfect Storm framework, the three most significant epigenetic stressors are: high-stress fertility and pregnancy journeys, birth injuries and interventions (forceps, vacuum, C-section, induction, epidural), and early exposure to toxins and medications. These three stressors during critical developmental windows are the primary drivers behind the rise in chronic childhood conditions.
Why is the medical system slow to accept epigenetics?
Epigenetics undermines the genetic predeterminism model that has justified pharmaceutical-based treatment for decades. If genes are destiny, patients need medications for life. If environment shapes gene expression, the answers lie in lifestyle change, toxin reduction, and nervous system support, none of which fit the conventional treatment model. Dr. Tony Ebel notes the research has pointed in this direction for 10 to 20 years; the clinical system is simply slow to follow.
How can Neurologically-Focused Chiropractic Care support epigenetic health?
Neurologically-Focused Chiropractic Care addresses the nervous system function that mediates the relationship between environment and genetic expression. By reducing nervous system interference, particularly in the upper cervical spine, and helping the body shift out of chronic Sympathetic Dominance (fight-or-flight mode), this approach creates the internal environment where healing and healthier gene expression become possible. It works alongside lifestyle and toxin reduction as part of a whole-environment approach.
