Gut Health

Summary. Bacteria that produce short-chain fatty acids (SCFAs) - such as butyrate, propionate, and acetate - break down dietary fibers and other complex carbohydrates that human digestive mechanisms cannot digest, converting them into SCFAs.

Summary. Hydrogen sulfide (H2S)-producing bacteria in the gut can play a complicated role in gut health. At low, physiologically normal levels, hydrogen sulfide can have some signaling or regulatory functions. However, when these organisms become overly abundant, they can increase H2S concentrations to levels that may cause or exacerbate intestinal inflammation and epithelial damage.

Summary. Mucin-degrading bacteria help maintain a healthy turnover of the mucus layer. This process allows for the production of fresh mucus, which helps keep the barrier robust. However, if these bacteria become overabundant then degradation can outpace replenishment. The result is a thinned mucus layer, exposing the intestinal epithelium to potential pathogens and increasing the risk of “leaky gut” or inflammatory conditions.
