Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Resistant starch is a type of dietary fiber that resists digestion in the small intestine and reaches the colon largely intact. Its primary role is not to directly support the small intestine, but rather to benefit the gut as a whole, particularly the colon. However, some scientific evidence suggests that resistant starch can have a positive impact on the small intestine's health by modulating gut microbiota and enhancing the production of short-chain fatty acids (SCFAs), such as butyrate, through fermentation processes in the colon. These SCFAs can have systemic effects, including influencing small intestinal health by improving gut barrier function and reducing inflammation. Studies in humans and animals have shown that diets high in resistant starch can increase intestinal transit time and may favorably alter the composition of the gut microbiome, which could indirectly benefit the small intestine. However, direct effects of resistant starch specifically on the small intestine are less well-studied compared to its effects on the large intestine. Therefore, while there is some scientific rationale and preliminary evidence for its supportive role in small intestinal health, the strength of the evidence is moderate rather than robust, and its use for this purpose is not as extensively validated as it is for colon health.
