Official title
Berries and Bones: The Effect of Polyphenolic Metabolites From Blueberries on Bone Turnover
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study uses a bone labeling calcium tracer methodology to compare the dose-response effect of blueberry consumption on calcium retention and bone loss. Post-menopausal women will receive food or beverage products containing freeze-dried blueberries in the amount equivalent to 0.75 (low), 1.5 (medium), and 3 cups (high) of fresh blueberries per day over a 42-day period. The hypothesis is that the polyphenolics found in blueberries will reduce calcium loss from bones.
