I’d encourage you to make time to watch the Gut Health Masterclass course if you haven’t already. In there I dive deep into how digestion works, how it dysfunctions, how it connects to the rest of the body, and practical solutions for each stage of digestion.
In the meantime, here’s a video on the triggers and causes of leaky gut.
Butyrate is a a type of short chain fatty acid (SCFA) we can consume and produce in the colon. Here’s the short video that explains how we produce butyric acid in the colon, and what happens when dysfunction in the colon happens like leaky gut.
Butyrate is produced by bacteria in our colon when they ferment carbs (mostly soluble fiber) which nourishes the colon and is believed to be the most anti-inflammatory SCFA.
If low, we can increase butyrate production by supporting our microbiome health through fermented foods and/or probiotic supplements when needed.
We can also increase it with larch gum (arabinogalactan) and other fibrous additions like psyllium husk, but again – those with IBS/SIBO will want to correct their dysbiosis first and go slow on having too much fiber initially.
