topicBlueberry Visual Performance Randomized Trial
claimPurpose Despite equivocal human study data, anthocyanin-rich blueberries are associated with positive glycaemic effects which could benefit satiety and other cardiometabolic outcomes.

sourceA randomised, double-blind, placebo-controlled trial to assess the postprandial dose-dependent effects of wild blueberries on metabolic and cognitive outcomes following a high-carbohydrate breakfast.
topicBlueberry Visual Performance Randomized Trial
claimConclusion Wild blueberry effects on postprandial glucose and appetite hormone responses were evident at anthocyanin doses of 300 mg and above but did not impact other outcomes in healthy adults.

topicBlueberry Visual Performance Randomized Trial
claimThe objective of this study was to examine the dose-dependent effects of freeze-dried wild blueberries on postprandial glucose response simultaneously with changes in satiety, blood pressure and cognitive function.
