Scope Published data support that gut microbiota play an important role in the pathological process of obesity and related metabolic disorders. In current study, it is investigated whether a standardized extract from Jamun ( Eugenia jambolana ), widely consumed tropical fruit, could alleviate alter microbial community high‐fat diet (HFD)‐fed mice. Methods results C57BL/6 mice are fed either standard (SD) or HFD with without fruit (JFE; 100 mg kg −1 day ) by oral gavage for 8 weeks. JFE...
