What is this study about?
This study compares how different types of sodas affect blood sugar levels in adults who drink soda daily. We're testing whether switching from regular soda to a prebiotic soda with added fiber can help support healthy blood sugar levels. Your participation, providing blood samples and daily feedback, helps us understand if this simple beverage swap could be a practical way to manage blood sugar.
