Randomized Crossover Study on Effects of Six Cranberry-Based Fruit Juices on Blood Sugar and Insulin in Adults Aged 18 to 45

What this Trial Is About

Researchers are investigating how different cranberry-based fruit juices affect blood sugar and insulin levels after eating. The study focuses on the immediate metabolic responses to these beverages, which may help clarify their role in diet and metabolic health. This trial is a randomized, controlled crossover design sponsored by Ocean Spray Cranberries, Inc., evaluating various fruit juice formulations in healthy adults. Participants will consume six different study beverages one at a time in a set order. Each visit involves drinking one type of fruit juice, followed by a 3 to 7-day break before the next beverage. The beverages include versions with zero sugar, low sugar two formulations, full sugar two formulations, and a glucose control drink. This crossover design allows each participant to experience all study products. During the study visits, participants will have blood samples taken to measure glucose, insulin, and GLP-1 hormone responses over 2 hours after consuming each beverage. Researchers will track blood sugar and insulin levels at multiple time points to assess changes and peak concentrations. The total participation period includes multiple visits spaced by wash-out periods, ensuring detailed monitoring of metabolic responses to the different juices.
