Aronia Juice's Metabolic Boost Depends on Your Gut Microbiome

A study using humanized mice found polyphenol-rich Aronia juice can shield against high-fat-diet–induced metabolic disruption, but benefits vary with the gut microbiome: mice with low-inflammatory microbiomes showed preserved gut diversity and favorable metabolic markers after Aronia treatment, while those with high-inflammatory microbiomes did not exhibit the same benefits.
