Study Design

Allocation randomized
Endpoint classification pharmacodynamics study
Intervention model crossover assignment
Masking double blind (subject, caregiver, investigator, outcomes assessor)
Primary purpose basic science
Subjects in this group ate capsule filled with sucralose 200 mg for 4 weeks (week 1-4) and measured oral glucose tolerance test (OGTT), acute insulin response (AIR), and gut microbe examination at week 4.
sucralose Trichlorosucrose
Consumption of capsules containing either 200 mg sucralose (equivalent to diet soda 3 cans) per day for four weeks
(Placebo Comparator)
Subjects ate empty capsule (placebo) for 4 weeks (week 1-4) and measured OGTT, AIR, and gut microbe examination at week 4.
Consumption of empty capsule everyday for 4 weeks

Additional Information

Official title Effects of Sucralose Consumption on Glucose Metabolism, Incretin and Gut Microbiota in Healthy Adult
Principal investigator Chutintorn Sriphrapradang, M.D.
Description Artificial sweeteners such as sucralose, are among the most widely used food additives worldwide. Artificial sweetener consumption is considered safe and beneficial owing to their low caloric content. However, many emerging evidences showed artificial sweeteners may induce glucose intolerance. The objectives of this study were to determine the effect of sucralose on glycemic response, insulin secretion, insulin sensitivity, incretin response, gut microbiota and food behavior in healthy subjects.
