This study aims to investigate the effects of a 6-week dietary intervention of 22 g freeze-dried whole wild blueberry powder. The outcomes include measures of depression, anxiety, anhedonia, cognitive function, and biomarkers of inflammation and oxidative stress.


A randomized, double-blind, placebo-controlled, parallel-design study assessing the effects of a 6-week intervention of wild blueberry powder in young adults with depressive symptoms. A total of 60 participants will be randomly assigned to either 22 g blueberry powder or a matched placebo powder consumed daily with water. The severity of depression, anxiety, anhedonia, perceived stress, and quality of life will be measured at baseline and 6 weeks later. In addition, we will assess changes in cognitive function and transient mood 2 hours after consuming a single dose of blueberries.
