Higher dietary intake of fruit, whole grains, and coffee is associated with increased circulating levels of hippurate, a metabolite produced by gut microbiota that serves as a marker for higher gut microbiome diversity.

To potentially support gut microbiome diversity and metabolic health markers, increase your intake of fruit, whole grains, and coffee. These foods are associated with higher levels of hippurate, a metabolite linked to a lower risk of metabolic syndrome.

GoodSupportsHIGH confidence
Higher intakes of fruit and whole grains were associated with higher levels of hippurate cross-sectionally and longitudinally.
