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 Cognitive Performance Randomized Trial
claimBy improving satiety response to a meal, this may reduce the risk of obesity and other metabolic conditions such as type 2 diabetes mellitus or metabolic syndrome.
