The research investigates the effects of cranberry polyphenols on cognitive function and stress-related hormones in healthy young adults. The Cranberry Institute's double-bind study involved 72 college students aged 20 to 25. Participants consumed eight fluid ounces of a [cranberry drink](https://www.trendhunter.com/trends/sour-blueberry-lemon-craisins) daily with breakfast over a 12-week period, while a control group received a placebo. The results showed that those in the cranberry group experienced significant changes in circulating polyphenol metabolite concentrations, along with reduced diurnal cortisol levels — a hormone involved in stress regulation — and demonstrated enhancement in certain [cognitive functions](https://www.trendhunter.com/trends/goodrays-1), specifically short-term and phonological memory.
