Have you ever been told that your health challenges are just "in your genes"? While genetics play a role in shaping who you are, they don’t tell the whole story. Science now shows that your daily choices, environment, and even your mindset can influence which genes are activated and how your body functions.
As a holistic nutritionist and gut health expert with 12+ years experience, I’ve seen firsthand how changing your environment - both physical and emotional - can transform your digestion and overall well-being.
Let’s explore how epigenetics works and how you can use this knowledge to take charge of your health.
What Is Epigenetics?
Epigenetics is the study of how your environment influences gene expression.
Your genes sit locked away in your DNA, protected by a protein shield. This shield acts like a bodyguard, preventing genes from being read and expressed. The only way to unlock a gene is through an environmental signal.
Something as simple as nutrition, stress, or emotions can trigger this change. It might sound simple, but the impact is profound. Environmental factors have been shown to create more than 30,000 variations of a single gene blueprint!
So, instead of being fixed, your genes act more like dimmer switches - your lifestyle choices can turn them on or off. That means things like food, stress, and even your thoughts can influence how your body functions, including your digestion.
Your genes aren’t fixed, but responsive. Just like your DNA holds your genetic code, your daily choices - from food to stress - hold the key to how your body functions, especially your digestion.
Why It Matters for Your Digestion and Health
Your body is constantly responding to your environment. The signals you send - through food, stress, sleep, and even mindset - can activate or suppress genes, affecting how you feel and function every day. Here’s how:
Nutrition: Whole, nutrient-dense foods provide your cells with the right information. Processed foods, artificial additives, and excess sugar can create inflammation and digestive issues.
Stress Levels: Chronic stress can disrupt gut bacteria, alter digestion, and trigger inflammation. Managing stress supports better cellular and digestive function.
Sleep Quality: Restorative sleep allows healthy gene expression for your body to repair and regulate digestion, energy, and mood.
Toxins & Chemicals: Pesticides, artificial ingredients, and household chemicals can alter gene expression. Reducing exposure supports better gut and overall health. [Check out my blog Reduce Toxins for Gut Health to learn more.]
Mindset & Beliefs: Your thoughts directly impact your stress response. Positive affirmations and supportive beliefs foster a healing environment, while negative self-talk can trigger resistance and symptoms.
As you can see, your mind plays a significant role in influencing your environment. The human brain consists of both subconscious thought and self-conscious awareness. The trouble lies when there’s conflict between the two. Have you tried to make a change out of sheer willpower, only to falter? That may be your subconscious mind at work.
If you constantly tell yourself that you can’t heal, that you’re stuck with poor digestion, or that you’ll never feel better, your mind might resist change. But, you can change your thoughts and story. By consciously shifting your mindset and perceptions, you take a giant step toward regaining control over your health.
Foods like garlic, ginger, and fresh vegetables send supportive signals to your cells, promoting digestion and reducing inflammation. Unlike processed foods and added sugars, nutrient-dense choices help your gut thrive from the inside out.
How to Support Better Digestion Through Your Environment
Despite having positive thoughts and perceptions, there are still environmental stressors you may face - pesticides, artificial ingredients, trans fats, processed foods, overtraining, work pressure, financial worries, and emotional stress. Whether physical or emotional, stress puts your body into survival mode, making it harder to grow, repair, and thrive.
Here’s where you can begin - small steps you can take at your own pace to support your genes and well-being:
1. Nourish Your Gut. Prioritize whole foods, fiber, probiotics, and hydration to support digestion.
2. Reduce Stress. Try deep breathing, meditation, or a gratitude practice to shift your body's stress response.
3. Prioritize Rest. Create a bedtime routine to improve sleep quality and support gut health.
4. Minimize Toxins. Choose organic when possible, reduce processed foods, and opt for natural household products.
5. Reframe Your Mindset. Replace negative self-talk with supportive, empowering affirmations about your health journey.

Final Thoughts: Your Environment is a Conversation With Your Body
Supporting your digestion isn’t just about what you eat. It’s about the world you live in, the thoughts you carry, and the way you respond to life’s demands. The beauty of epigenetics is that it reminds us we’re not stuck. You’re in dialogue with your body every day, and your environment speaks volumes.
When you begin shifting the signals - choosing foods that feel good, slowing down, clearing space for rest, and reshaping the story you tell yourself - you send a message of safety and support. That’s when your body can finally start to heal.
You don’t need to overhaul everything overnight. Just one choice, one breath, one mindset shift at a time is enough to change the conversation - and your health.
