Prebiotic intake reduces the waking cortisol response and alters emotional bias in healthy volunteers.

The effect of hormonal contraceptive on the first sample of salivary cortisol after waking showed a trend for lower levels in females taking contraceptives compared to those who were not (mean (SD) = 8.20 (3.42) vs. mean (SD) = 10.65 (4.37), F (1,17) = 3.74, p = 0.07); however, this difference was stable across days of testing and treatment groups (all interactions’ p values >0.7).
