Effect of Polyphenol-Rich Dark Chocolate on Salivary Cortisol and Mood in Adults.

The aim of the present study was to investigate whether ingestion of polyphenol-rich dark chocolate improved salivary cortisol levels and subjective mood states in adults recruited from a health and social care setting.
