Gedetailleerde beschrijving
Participation in this study will last for a minimum of 35 days (Phase I: 14-days; baseline with removal of all NNS (eg saccharin, sucralose, steviosides, aspartame, acesulfame-k, erythritol) from the diet, Phase II: 21-days; sucralose intervention, and will involve one virtual visit (study visit 1) and two in-person study visits (study visit 2 and study visit 3).
Fecal & urine samples will be collected before/after each phase. Blood will also be collected.

Experimenteel: Crohn's participants
Crohn's participants will consume artificial sweetener: sucralose
|
Participants will consume 2 sachets/day during the exposure period resulting in the following daily dose: sucralose 2.5mg/kg.
This dose is below the acceptable daily intakes (ADI) of 5mg/kg.

Quantify the change in Crohn's Disease Activity Index.
The Crohn's Disease Activity Index (CDAI) is a validated clinical instrument used to quantify Crohn's disease activity.
It evaluates 8 components over a 7-day period: number of liquid or very soft stools, severity of abdominal pain, general well-being, extraintestinal complications, use of antidiarrheal medications, presence of an abdominal mass, hematocrit levels, and body weight deviation.
Each component is multiplied by a specific weighting factor and summed to calculate a total score.
Total scores range from 0 to approximately 600 points, where lower scores indicate lower disease activity.
A score of <150 indicates clinical remission, while a score of >450 indicates severe disease.
A negative change from baseline indicates clinical improvement.
