Research indicates that vinegar consumption can beneficially regulate the gut microbiome and metabolome. In a study involving mice, administration of Shanxi aged vinegar (SAV) led to significant decreases in inflammatory factors and alterations in gut microbiota composition, including increased levels of beneficial bacteria such as Akkermansia and Verrucomicrobia. These changes were associated with enhanced immune responses and reduced inflammation, suggesting that vinegar intake may promote a healthier gut environment.
