If a report highlights low abundance of butyrate-producers, what is the actionable dietary modification suggested?

Increasing resistant starch and fermentable fiber.

When analyzing a complex gut report, actionable gaps should be prioritized over esoteric findings, especially concerning bacteria linked to critical functions. Butyrate is a short-chain fatty acid (SCFA) vital for colonocyte energy, and its production relies on specific gut species metabolizing certain dietary components. Therefore, if a report shows an unusually low presence of these known producers, the most evidence-based and immediate dietary change involves adjusting inputs that feed these microbes. This means consciously increasing the consumption of resistant starch and fermentable fiber, which serve as the necessary substrates for these beneficial bacteria to flourish and produce the required SCFAs.
