Clinical Trial Summary

This study aims to evaluate the acute (1-day) and repeated (2-week) effects of combinations of Sweeteners & Sweetness Enhancer blends on metabolic, sensory, neuro-behavioural and microbiota-mediated processes involved in satiety, consumer preferences and health.


Clinical Trial Description

This protocol has the overall objective to evaluate the acute (short-term, 1 day) and repeated (medium-term, 2 week) effects of combinations of sweeteners and sweetness enhancers (S&SEs) on metabolic, sensory, neuro-behavioural and microbiota-mediated processes involved in satiety, consumer preference and health, and to explore mechanistic processes, genetic background, safety issues and consumer perspectives. There are 5 products being tested in 3 different formulations (sucrose-sweetened control vs 2 reformulated with S&SE). Each product will be tested at 2 intervention sites in double-blind cross-over trials with 48 subjects (24 per site) tested per product. Therefore a total of 240 subjects will take part across the 5 intervention sites (Navarra, Leeds, Liverpool, Copenhagen, Lyon). Using identical procedures each trial will consist of 2 Clinical Investigation Days (CIDs) scheduled 12 days apart for each of the 3 product formulations. A 2-week wash-out period will be given between formulations. The total duration of WP2 Phase 2 is 12 months, including a 5-month duration for each cross-over trial. ;
