Ep. 165: Gut Health and Food Allergies: What the Microbiome Has to Do With It
Part of the series: Allergy, Asthma & Immunology Innovations Podcast
This podcast was made in partnership with Allergy & Asthma Network.
You have probably heard the word "microbiome", but what does it actually mean for someone living with a food allergy?
Dr. Carina Venter, a registered dietitian and professor of pediatric allergy and immunology at Children's Hospital Colorado, joins us to break down the gut’s role in food allergies. She explains what the microbiome is, how it connects to the immune system, and what families can realistically do right now to support a healthier gut.
What we cover in our episode about gut health and food allergies
What the microbiome actually is. Understanding the bacteria living in your gut, why diversity matters, and what happens when that balance gets disrupted.
The connection between gut bacteria and food allergy. Research consistently shows that children with food allergies have lower levels of two key bacteria, and that gap may affect how the immune system responds to food.
Leaky gut and ultra-processed foods. What leaky gut actually means and research on emulsifiers.
Should you be taking probiotics? Which strains have the most research behind them, what to look for on the label, and why diet diversity may matter more than any supplement.
Practical steps for families. From a diverse diet to when to use supplements.
