Consumption of Phytoestrogens May Alter Gut Ecology
Published Thursday, December 1, 2005

JOUY-EN-JOSAS, France--Isoflavone supplementation may stimulate the growth of specific subgroups of gut microorganisms, according to a new study in the Journal of Nutrition (135:2786-92, 2005). In a double blind, placebo-controlled study coordinated through the Institut National de la Recherche Agronomique and the Germany Institute of Human Nutrition Potsdam-Rehbruecke, 39 postmenopausal women received isoflavone supplementation with or without a probiotic and prebiotic for two months. Isoflavones alone stimulated microorganisms of the Clostridium coccoides-Eubacterium rectale cluster, Lactobacillus-Enterococcus group, Faecalibacterium prausnitzii subgroup and Bifidobacterium genus; the effect was relatively long-lasting, particularly in the bifidogenic area. Individual probiotic strains supplied in conjunction with isoflavones were detected by the researchers during the passage of the product through the gastrointestinal tract; ingestion of fructooligosaccharides (FOS) markedly increased bifidogenic activity.
