Daily intake of enriched yogurt may help people cope with stress

stress - yogurt

The aim of this study was to evaluate the impact on chronic stress of yogurt enriched with bioactive peptides and group B vitamins, compared to normal yogurt.

Sixty-seven individuals aged from 18 to 63 suffering from severe anxiety were enrolled in this randomised, double-blind study. To detect changes in psychological and physiological stress, State-Trait Anxiety Inventory, Profile of Mood States, salivary cortisol, inflammatory markers, blood pressure, heart rate variability (HRV) and actigraphy were monitored.

Results showed higher ratings of vigor and reduced feeling of inefficiency in the active group. HRV (baseline adjusted mean 49.1 ± 2.3 ms) and recovery index (106.6 ± 33.4) were significantly higher in the active group than in controls (42.5 ± 2.2 ms and 80.0 ± 29.3). Even if these results still need confirmation, they once again put the anti-stress effects of certain peptides in milk proteins into the spotlight.
