Berries, Inflammation, and Gut Microbiome (NCT04100200)

Polyphenols and Human Gut Microbiome Interactions: Role of in Ameliorating Inflammation

๐Ÿ”ต Active, Not Recruiting Observational / Diagnostic ๐Ÿ“‹ Clinical Research Protocol Sponsor: Clinical Nutrition Research Center, Illinois Institute of Technology

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The primary objectives are to characterize changes in indices of systemic and gut inflammation, assess host- and microbial-derived metabolite pools, and describe and link functional metagenomics and metatranscriptomic alterations in the gut microbiome with metabolite and inflammatory outcomes after acute (24hr) and chronic (4 week) intake of anthocyanins and ellagitannins from strawberry and red raspberries compared to a control diet (negative control), FOS (positive control, non-polyphenol, carbohydrate-based fermentable fiber/pre-biotic), or combination diet (berry composite + FOS) in human participants with low-grade inflammation.
