Potato Resistant Starch for Gut Health: The Butyrate Connection

Resistant starch behaves like fibre rather than a digestible carbohydrate — it resists digestion in the small intestine and becomes one of the most reliable substrates for butyrate production in the colon.

Why butyrate matters

Butyrate is a short-chain fatty acid produced by gut bacteria fermenting resistant starch. It's a primary fuel source for colon cells and is associated with gut barrier integrity in category-level research.

The glucose-response angle

Resistant starch research on post-meal glucose response is reasonably solid at the category level — a genuine mechanism distinct from its fibre-like fermentation role.

The same dose caveat applies

As with inulin, resistant starch research typically runs at gram-scale doses. A 100mg capsule contribution is a token amount by comparison — a real ingredient, contributing modestly rather than at a clinically-matched level.
