In this episode

• A plain-language primer on genetics vs. epigenetics
• Why the extra chromosome in Trisomy 21 makes epigenetics especially relevant
• How DNA methylation connects to detoxification, cognition, and cellular repair
• The genes on chromosome 21 that tend to run "loud," and what that can mean day to day
• Nutrients, antioxidants, and foods that support healthy gene expression
• How functional medicine personalizes a plan instead of taking a one-size-fits-all approach
• A Q&A on common questions parents ask about epigenetics

Show notes

Epigenetics is the study of how our environment, the food we eat, the sleep we get, the stress we carry, the toxins we're exposed to, influences which genes are turned up, turned down, or left quiet. Your DNA is the cookbook. Epigenetics decides which recipes actually get made, and how often.

That distinction matters deeply in the Down syndrome community. Trisomy 21 means a third copy of chromosome 21 and roughly 300 extra active genes, which can drive patterns of inflammation, oxidative stress, and altered methylation across the lifespan. Genes like DYRK1A, RCAN1, SOD1, APP, CBS, and IFNAR1/2 sit at the center of those conversations in the research.

In this episode, Dr. Blake Butler, DC walks through how a functional medicine approach supports healthier gene expression at a daily-habit level. That includes nutrients involved in methylation like B12, folate, and choline, minerals like zinc, antioxidant support through glutathione, NAC, and vitamins C and E, and an anti-inflammatory way of eating built around omega-3-rich foods and Mediterranean-style meals. It also includes the less glamorous pieces: reducing toxin exposure at home, protecting sleep, and giving the nervous system a chance to rest.

The takeaway Blake leaves families with: focus on what you can change. Food, environment, sleep, and daily habits are real levers, and small, consistent steps can add up.

About the podcast The Down For Health Podcast is hosted by Dr. Blake Butler, DC, a functional medicine practitioner with postgraduate training through The Institute for Functional Medicine and the founder of Down For Greens. Blake's older brother Nick has Down syndrome, and that lived experience shapes every episode. The show exists to give families, caregivers, and clinicians a functional medicine lens on the health questions that matter most in the Down syndrome community.
