See why resistant starch is the Unsung Hero of Dietary Fiber.

Here's why resistant starch is crucial for supporting a healthy gut microbiome:

It’s a starch that arrives in the large intestines intact like insoluble fiber, but is fermentable like soluble fiber demonstrating the benefits of both types of fiber.

It increases healthy endogenous bacteria, like Bifidobacterium, which in turn help to modulate the immune system and support healthy digestion.

It selectively feeds Bifidobacterium, its primary degrader, that cross feeds other bacteria like Akkermansia, which helps to support gut barrier function and weight management.

It works in areas beyond the gut like metabolic health, helping to reduce insulin resistance. Its effects on kidney function are currently being studied.
