About this study
To study the potential impact of a diet rich in both Slowly Digestible Starch (SDS) and Resistant Starch (RS), we propose a 2-month nutritional intervention study in which we will study the evolution of carbohydrate variability and metabolism and health-related parameters in 40 volunteers with insulin resistance. Regular sampling of blood, urine and faeces as well as continuous measurement of blood glucose levels will be performed to assess changes in blood glucose levels, insulin resistance, lipid metabolism, inflammation and the composition of the microbiota following the introduction of starch products rich in SDS and RS into the diet.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
To study the potential impact of a diet rich in both Slowly Digestible Starch (SDS) and Resistant Starch (RS), we propose a 2-month nutritional intervention study in which we will study the evolution of carbohydrate variability and metabolism and health-related parameters in 40 volunteers with insulin resistance. Regular sampling of blood, urine and faeces as well as continuous measurement of blood glucose levels will be performed to assess changes in blood glucose levels, insulin resistance, lipid metabolism, inflammation and the composition of the microbiota following the introduction of starch products rich in SDS and RS into the diet.

Questions about this trial
What is this clinical trial studying?
A study testing Balanced diet high in Slowly Digestible Starch and Resistant Starch and Balanced diet low in Slowly Digestible Starch and Resistant Starch in people with Insulin Resistance, run by Mondelēz International, Inc. at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 17 inclusion and 45 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Julie-Anne Nazare, PhD (+33 4 78 86 29 81, julie-anne.nazare@univ-lyon1.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in MAGE measured on 3 occasions between diets High or Low in SDS and RS (time frame: Evaluations done before, after 1 week and after 2 months on a diet). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Feb 2026.
