Not all fiber does the same job. Resistant starch is the type of fiber most modern diets have largely stripped out, and research suggests it may be one of the nutrients your gut microbiome misses most. Carl Pradelli explains what it is and why it matters.
What You'll Learn:
- What resistant starch is and how it behaves differently from ordinary starch and other fibers.
- Why current intake sits near 4 grams a day when 15 to 20 grams is often cited for gut and metabolic support.
- How resistant starch may feed beneficial microbes like Bifidobacterium and Akkermansia.
- Why Akkermansia is drawing research interest for metabolic health, healthy blood sugar metabolism, GLP-1, and the gut barrier.
- How a low-dose resistant starch ingredient helps fill the gap and can easily fit into a daily routine.
A lot of people know fiber is important. Fewer realize that not all fiber is the same. In this episode, Carl Pradelli, CEO and Co-Founder of NatureCity, makes the case that resistant starch may be one of the most overlooked nutrients missing from diets in the 21st century.
For most of human history, people regularly ate starchy plants that naturally contained resistant starch, which gave the gut microbiome fermentable fuel. Modern food processing, refinement, and cooking practices have steadily removed much of it. Current intake is estimated at only about 4 grams per day across the United States and Europe, while 15 to 20 grams per day is often cited for supporting bowel, gut, and metabolic health.
Carl explains what makes resistant starch unique. It resists digestion in the small intestine and reaches the large intestine intact, where beneficial microbes can ferment it. That gives it qualities of both insoluble and soluble fiber. Research suggests this fermentable fiber may selectively feed beneficial bacteria, including Bifidobacterium and Akkermansia.
Akkermansia is drawing particular research interest for metabolic health and healthy blood sugar metabolism. Studies suggest it may help support healthy GLP-1 levels and help the body use insulin more efficiently, and it appears to play a role in protecting the gut lining and gut barrier function.
Carl walks through additional research areas discussed for a low-dose resistant starch called Solnul that can deliver key benefits with just 3.5 grams per day. These include supporting a healthy inflammation response in the gut, consistent stool quality, intestinal barrier function, nutrient absorption, the gut-skin connection, and broader metabolic markers. Every claim stays in research framing.
The takeaway is practical. Resistant starch is a fermentable fiber the modern diet provides far less of than it once did and filling that gap at a sensible daily dose with Solnul may be a simple way to support the gut microbiome.
NatureCity features this low-dose resistant starch ingredient in its advanced TrueDYB digestive formula.
