Prunes consumption changes the gut microbiome in postmenopausal women, finds study

The randomized controlled trial included 143 postmenopausal women between the ages of 55 and 75. Participants were assigned to one of three treatment groups: no prunes (n=52), 50g prunes per day (n=54), or 100g prunes day (n=37). Results collected at the 12-month mark indicated significant changes in the microbiomes for those in the prune treatment groups – most notably, the enrichment of the Lachnospiraceae family of bacteria. Researchers suggest that these results may have implications for the use of prunes as a non-pharmacological whole food intervention for gut health.2

“Consumers are becoming more concerned with their gut health and this study supports prunes’ long-standing reputation as a gut-healthy food. Prunes are a natural, whole food that is easy and convenient for consumers to incorporate into their daily meals or snacks,” says Andrea N. Giancoli, MPH, RD, Nutrition Advisor to the California Prune Board.

This new study adds to the growing body of research that explores the relationship between prune consumption, gut health, and the potential favorable effects on other major body systems. For instance, a recently published scientific review from Pennsylvania State University suggests that the phenolic compounds and dietary fiber content in prunes may alter the gut microbiome in a manner that ultimately supports bone health.3
