The study found that the aronia berry matrix affects how aronia polyphenols interact with gut microbiota in healthy mice, leading to differential impacts on SCFA, microbiota, and fecal anthocyanin levels.
The objective of this study was to determine the extent that the aronia berry matrix affects gut microbiota composition, fecal short chain fatty acids (SCFAs), and colonic anthocyanins in healthy mice. C57BL/6J mice were fed AIN-93 M control diet (C) or C with whole aronia berry (AB), aronia extract (AE), or polyphenoldepleted AB (D) at the expense of cornstarch. After one week of feeding, AB and D increased fecal anthocyanins more than AE. Diets differentially affected SCFA and microbiota. AB fecal SCFA was associated with increased metabolism of succinate and pyruvate to butyrate. D increased acetic acid production, was associated with increased abundance of predicted genes for fermentation of carbohydrates to acetyl-coA. AB and D also increased predicted abundance of microbial catechol metabolism pathway I relative to C, which was attributed to enrichment of Lachnospiraceae. Therefore, the berry matrix impacts how aronia polyphenols interact with the gut microbiota in healthy mice.
