Additionally, SCFAs can exert other beneficial effects, acting as histone deacetylase inhibitors, playing a crucial role in epigenetic regulation and acting as anti-cancer agents [16,49]; and increasing transit time and satiety by activating hormones such as glucagon-like peptide 1, peptide YY, and leptin via their endogenous receptors Free Fatty Acid Receptors 2 (FFAR2) and 3 (FFAR3) [50]. Here, FFAR2 is linked to cancer.
