Detailed description

This is a double blinded randomized control trial aiming to characterize the profile of polyphenol-derived metabolites in plasma and urine for children ages 11-12 years supplemented short term with wild blueberry powder. The study will assess if a short-term supplementation (5 days) with wild blueberry powder impacts immune responses as well as markers for cardiovascular and bone health. Up to 44 children will be recruited. The participants will attend three visits at Arkansas Children's Nutrition Center.
