Study summary

The objective of this project is to determine the impact of incorporating brewers' spent grain into cookie formulations on postprandial blood glucose absorption levels following consumption. The methodology for assessing blood glucose response to cookies formulated with brewers' spent grain is described as follows.

A total of 20 participants will be recruited from the Universidad Católica del Uruguay. Volunteers will be recruited through institutional email dissemination, with Dr. María Belén Gutiérrez serving as the research contact.

Eligible participants will be healthy adults without diagnosed diseases and not taking regular medication. Inclusion criteria will be: men and women aged 18 to 75 years and a body mass index (BMI) between 18.5 and 30 kg/m². Exclusion criteria will include: pregnancy, diabetes, special dietary regimens, recent surgeries, and hypersensitivity or allergy to any of the components of the tested foods.

A physical assessment will be performed for each participant, including waist and hip circumferences, body weight, and height. Each participant will be assigned a volunteer identification code, and the data analyst will be blinded to the identity of the participants. Volunteers may withdraw from the study at any time without any consequences.

Participants will be studied on four separate occasions (one session per week). On two occasions they will receive 30 g of a commercial María cookie, and on the other two occasions 30 g of a reduced-sugar cookie containing 17% extruded brewers' spent grain. During the study period, participants will be asked to maintain their usual lifestyle.

Participants will attend the University Clinic in the morning after an 8-10 hour overnight fast. After a fasting blood sample is obtained, the corresponding treatment will be provided, and participants will have 15 minutes to consume it. Capillary blood samples will be collected at 15, 30, 45, 60, 90, and 120 minutes after the start of treatment consumption.

Blood sampling will be performed via capillary puncture using a commercially available glucometer, with disposable lancets used for each measurement and safely discarded after each sample. Sample collection will be carried out by trained personnel from the Department of Health and Well-being of the Universidad Católica del Uruguay.

During the testing period, participants will be allowed to drink up to 250 mL of water and must remain seated. For each participant and each treatment day, a data collection sheet will be used to record all measurements. After each experimental session, participants will receive a breakfast voucher.

Inclusion criteria

  • (BMI) between 18.5 and 30 kg/m².

Exclusion criteria

Exclusion Criteria:

  • Pregnancy
  • Diabetes

  • Food allergies
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2026 (actual). Primary completion is estimated for Jul 2026, 4 months after the start.

Of 2,066 non-industry interventional studies with no phase under Diabetes Mellitus, Type 2, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 40. This study's planned 4 months is below that.

Counting every sponsor, half of 2,243 studies reached it within 21 months; a quarter within 10 and three quarters within 39.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
