Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Raisins contain a significant amount of dietary fiber and polyphenolic compounds that represent an important substrate for microbiota fermentation which generates potentially beneficial end products, such as short-chain fatty acids. The mammalian gut contains a phylogenetically as well as functionally diverse microbiota that contributes to host physiology. To date, little is known about how increased raisin intake affects human gut microbiota composition. This research study will assess the effects of adding raisins to the diet of healthy adults on the bacteria from feces of human subjects and resulting self-reported GI symptoms as well as markers of immune function. The hypothesis is that by adding raisins to the diet this will result in changes in gut microbiota. Furthermore, the changes in microbiota will largely be beneficial, as evaluated by an increase in butyrate producers and bacteria associated with anti-inflammatory properties.
