We often hear, “You are what you eat,” but did you know that what you eat can also affect how your genes are expressed? Lifestyle modifications, including personalizing your nutrition, can help change your gene expression for optimal health and well-being.
What is Gene Expression?
Before I delve into how nutrition affects gene expression, let’s define it. Gene expression refers to the process by which information in a gene is used to create a functional product, such as a protein. It is essential for maintaining biological processes in the body, including growth and development, and can be influenced by environmental factors and lifestyle choices.
How Does Nutrition Affect Gene Expression?
Now that we understand what gene expression is, the question is: how does nutrition affect it? Nutrition can influence gene expression in several ways, including:
- Epigenetics: Epigenetics refers to changes in gene expression that are not due to changes in the DNA sequence itself. These changes can be passed down from generation to generation and can be affected by environmental factors, including nutrition. For example, research has shown that nutrients such as folate, vitamin B12, and choline can affect DNA methylation, a type of epigenetic modification that can influence gene expression.
- Nutrigenetics: Nutrigenetics studies how genetic variation affects an individual’s nutrient response. Certain genetic variations can affect how the body metabolizes certain nutrients, such as caffeine or alcohol.
- Gut Microbiome: The gut microbiome refers to the trillions of microorganisms that live in our digestive tract and can also influence gene expression. Research has shown that the gut microbiome can modulate the immune system, affect inflammation, and influence mood and behavior.

Personalizing Your Nutrition for Optimal Health
So, how can we use this information to personalize our nutrition for optimal health and well-being?
Here are a few tips:
- Get tested. Consider getting genetic testing to identify any genetic variations that may affect how your body metabolizes certain nutrients. This information can help inform your dietary choices.
- Focus on quality. Choose high-quality foods that are nutrient-dense and free from additives and preservatives. A diet rich in fruits, vegetables, whole grains, and lean protein can provide the nutrients necessary for optimal gene expression.
- Balance your gut microbiome. Eat various fiber-rich foods to promote the growth of beneficial gut bacteria. Probiotic-rich foods like yogurt and fermented vegetables or supplementing with a pre/probiotic combo can also support a healthy gut microbiome.
- Listen to your body. Pay attention to how your body feels after eating certain foods. If you notice adverse effects, such as bloating or digestive discomfort, consider eliminating or reducing these foods for a while.
- Seek the advice of a certified nutritionist or a registered dietitian who is a Functional/Naturopathic Medicine Practitioner. These specialists can help you personalize your nutrition plan to meet your needs and goals based on genetic variations, gut health, and lifestyle factors.
It is probably surprising that we aren’t as tied to our genetics as we once thought. You can change and restore your health to optimal just by completing these simple tasks. Personalizing your nutrition can significantly impact your gene expression, ultimately contributing to optimal health and well-being. By focusing on quality, balance, and individual needs, we can use nutrition to improve our genetic expression and achieve optimal health.
