Researchers from the University of Aberdeen have discovered that persimmons (specifically the Rojo Brillante variety) act as a potent prebiotic. The fermentation of persimmon fiber by gut bacteria produces short-chain fatty acids like butyrate and acetate, which maintain the integrity of the intestinal barrier. The study highlights that soluble fiber is particularly effective in stimulating the growth of beneficial bacteria such as Bacteroides and Oscillibacter, leading to significant anti-inflammatory and antioxidant benefits.
