Bioavailability and pharmacokinetics of (poly)phenols following consumption of selected blueberries and a blueberry-rich protein bar by adult males and females: a randomized, crossover, controlled trial.

Background: It is commonly believed that higher nutrient content equates to healthier foods and that food processing lowers nutrient content, although bioavailability studies often indicate otherwise. Blueberries, a rich source of (poly)phenols with proven health benefits, provide a feasible model to evaluate phytochemical bioavailability following consumption of raw and processed fruits.

Objectives: This study evaluates the effect of processing on the bioavailability of (poly)phenols following consumption of 4 interventions: 2 blueberry varieties (i.

The berry health tool chest - an evidence map and interactive resource.

Berry consumption is linked to diverse health benefits, but numerous questions remain regarding mechanism of action, dose efficacy, and optimal duration and frequency of intake. Addressing these outstanding questions requires an organized assessment of current research, to inform future study designs and fill critical knowledge gaps. Tools that organize such information will also facilitate consumer messaging, targeted nutritional health initiatives, and dietary intake guidelines.
