Colourful cans, gut-health promises and low-calorie claims have helped prebiotic sodas become one of the hottest new beverage trends. The researchers examined 108 prebiotic sodas launched in the United States between 2021 and 2025. Overall, prebiotic sodas occupied the middle ground. Although all prebiotic sodas contained more fibre than standard soft drinks, the fibre content varied greatly. In my assessment, this study offers valuable guidance for consumers rather than criticism of prebiotic sodas.
