Summary

This is a double-blind, controlled, parallel, randomized sensory study. The study will consist of two cohorts; habitual regular full-calorie Carbonated Soft Drink (CSD) consumers and habitual low-calorie CSD consumers. Each cohort will be randomized to one of 3 interventions for six months (24 weeks):

* Intervention 1: Control (full sweetness) beverage
* Intervention 2: Step-wise sweetness reduction series of beverages
* Intervention 3: Moderate sweetness (reduced sweetness) beverage

The primary outcome is to assess the perception changes in sweetness (magnitude scale) and sweetness liking (Likert scale) of a test product and a control product over a period of six months. The study endeavors to explore whether consumers of sweetened carbonated beverages can adapt liking to lower sweetness beverages after prolonged exposure of daily consumption of beverages with step-wise reduction of sweetness, or maintenance at reduced (moderate) sweetness.

Additional analysis will be to assess dietary compensation for sweetness in the step-wise and moderate reduction arms compared to the control arms (the full calorie and low calorie control beverages). Dietary analysis of calories and intakes of total sugar, added sugar, and servings of low-/non-calorie sweeteners will be assessed using a 3-day diet record pre-intervention and monthly for 6 months.
