Butyric acid: The crucial link

Short chain fatty acids (SCFA) positively affect the microbiota and modulate immune responses in the gut. SFCA can also offer a way to resist or limit the effects of a Salmonella infection. SCFAs are organic acids produced naturally by the body as by-products when dietary fibre and indigestible saccharides in the large intestine are fermented by the microbiota – bacteria, viruses and fungi that colonise the gastrointestinal system. Of the common SCFAs, butyrate has perhaps been the most studi
