1008 - Best Diet to Repair Gut Health (Important New Research)

1008 - Best Diet to Repair Gut Health (Important New Research)

Author: Dr. Michael Ruscio, DC March 2, 2026 Duration: 25:22

Could an enzyme deficiency explain why you have food intolerances causing bloating, loose bowels, reflux, brain fog, joint pain, skin issues, and more? Namely, sucrase isomaltase.

 

This enzyme, known as the sucrase-isomaltase enzyme, may be deficient in many people dealing with chronic GI issues. One study found that 8% of people were at an increased genetic risk for this deficiency (https://jpedres.org/articles/frequency-of-congenital-sucrase-isomaltase-deficiency-by-whole-exome-sequencing-is-it-really-rare/doi/jpr.galenos.2024.65625?utm_). Another study found that 25% with chronic GI symptoms had issues breaking down sucrose (https://pubmed.ncbi.nlm.nih.gov/36304608/).

 

Thankfully, a diet exists for this which has been studied and shown to be very effective. In fact, it's been shown to be as or even more effective than some of the best diets we currently have for improving gut health – therefore maybe the best diet for gut health?

 

Let's break down what this enzyme deficiency is, what the diet is, SSRD, and how this diet applies and can be helpful even for those with underlying fungal or bacterial overgrowth and leaky gut.
