abstract
Phytoestrogens are plant constituents which possess pro- and antiestrogenic properties and are therefore considered to play a beneficial role in the prevention of hormone related disorders. Soy is the major dietary source of phytoestrogens and hops contain the most potent phytoestrogen. The microbial metabolism is important for the bioactivity of the ingested phytoestrogens. There is a large interindividual variation in the metabolism partially due to the interindividual differences in activity and composition of the gut microbiota. The factors influencing the microbial metabolism are still largely unknown. A randomized intervention study with 150 healthy menopausal women was undertaken. Exclusion criteria were hormone replacement therapy, allergy to soy products and the use of antibiotics up to 3 month before the study. After a 4-day washout period, all participants delivered a fecal sample for incubation purposes and microbiological characterization, a control urine sample, and filled a gas collection bag for methane analysis. Participants ingested a soy or hop extract or 250 mL soymilk 3 times a day for 5 consecutive days. A 24-h urine sample of the fifth day was collected. Subjects consumed their habitual diets but were asked to avoid all products based on soy or hops during the study. A food frequency questionnaire was used to elicit the usual fat and fiber consumption.
