GC-MS determined distribution of urinary equol producers as affected by age, gender, and repeated ingestions of soymilk.

Status of equol excretion is likely a reflection of incidence risk of sex-hormone related diseases and deserves research attention. In this study, urine samples collected from 182 volunteers after soymilk ingestion were subjected to equol quantification using GC-MS. As categorized into male, female, and both genders and each category further classified into 6 age (year) categories, namely, <20, 21 to 30, 31 to 40, 41 to 50, >51 and overall, a trend indicating that the younger age the higher equol producer ratio was observed.

Particle size reduction effectively enhances the intestinal health-promotion ability of an orange insoluble fiber in hamsters.

The effects of particle size changes by micronization on the intestinal health-promotion ability of orange insoluble fiber fraction (IFF) were investigated in a hamster model by feeding 3 diets, which contained unmicronized IFF (control), jet-milled IFF, and high-pressure micronized IFF as the sole fiber source in diet. The results showed that the micronization treatments significantly altered the physicochemical properties of insoluble fiber. The consumption of the micronized fibers (6.
