Sweetness Liking Adaptation Clinical Trial
Official title:
Liking Adaptation to Beverages of Varying Sweetness Levels After Prolonged Exposure
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.
The secondary outcome 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.
