Effects of Chocolates With Different Cocoa Content on Postprandial Blood Glucose in Healthy Adults

This randomized controlled study evaluated how chocolates with different cocoa contents affect blood glucose levels after consumption in healthy adults. Sixty healthy adults aged 18-35 years were randomly assigned to one of six groups: a control group or groups receiving chocolate containing 55%, 60%, 72%, 80%, or 90% cocoa. All participants consumed a standardized meal. Participants in the intervention groups then consumed 40 g of their assigned chocolate. Blood glucose was measured before chocolate consumption and at 15, 30, 60, 90, and 120 minutes afterward. The study aimed to compare postprandial blood glucose responses among chocolates with different cocoa contents.
