About

This is a research study about the effects of blueberries on the health of children who do not eat much fruits and vegetables. By doing this study, we hope to find out what nutrients from blueberries appear in the blood and urine of the child

Full 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.
