To assess the effects of consumption psyllium seed husk on fecal bifidobacteria in healthy women and ability to metabolize vitro.Poor microbiologic evidences are nowadays available concerning promote growth human gut.Eleven consumed 7.0 g/d for 1 month. Viability feces was assessed at different time points.In vivo results showed that average content viable not significantly affected even if counts were found increase after treatment 6 out 11 having low initial concentration. In vitro trials conducted strains isolated from treated failed confirm prebiotic potential undigested husk, whereas with simulated gastric pancreatic juices mimicking physical chemical alterations during gut transit allowed Bifidobacterium isolates as carbon source a medium deprived sugar.Psyllium can be metabolized by only partial hydrolysis. Bifidogenic detected case level before treatment.
