This non-randomized acute clinical trial evaluates the effect of consuming a water-based solution of Cimarrón bean extrudate on platelet function and postprandial glycemia in adults. Participants will consume a single 10-gram dose of Cimarrón bean extrudate dissolved in water. Blood samples will be collected before and after the intervention to assess platelet reactivity using flow cytometry and to measure glucose levels through colorimetric spectrophotometry. The total intervention period will last approximately 8 hours. This study aims to explore whether the acute consumption of this legume-based functional product can influence hemostatic and glycemic responses in the postprandial state.
This clinical trial aims to evaluate the acute effects of consuming a beverage made from Cimarrón bean extrudate on platelet function and postprandial blood glucose levels in adult participants. The study involves a single-arm, non-randomized, open-label design in which each participant will consume a single oral dose of 10 grams of Cimarrón bean extrudate dissolved in water (SAEP: Solution of Cimarrón Bean Extrudate in Water). The trial includes baseline and post-intervention assessments of platelet reactivity using flow cytometry, employing specific agonists (CRP, TRAP, ADP) and labeled antibodies (anti-fibrinogen FITC, PE-CD61/CD62). Blood glucose levels will also be measured at multiple time points using colorimetric spectrophotometry to evaluate postprandial metabolic response. The total study duration per participant is approximately 8 hours, including fasting baseline measurements, administration of the intervention, and postprandial monitoring. This study seeks to provide preliminary data on the potential hemostatic and glycemic effects of a legume-derived functional food ingredient in a controlled, acute setting.

Change in platelet reactivity after acute consumption of SAEP
Platelet reactivity will be assessed by flow cytometry using CRP, TRAP, and ADP as agonists, with fluorescent antibodies (anti-fibrinogen FITC and PE-CD61/CD62). Measurements will be performed before and after consumption of SAEP to evaluate acute changes in platelet activation.
Time frame: Baseline and 2 to 6 hours post-intervention
Change in postprandial blood glucose levels after consumption of SAEP
Blood glucose concentrations will be measured at baseline and postprandial time, 2 hours after consuming 10 g of Cimarrón bean extrudate dissolved in water. The aim is to evaluate the glycemic response and potential glycemia-lowering effects of the intervention.
Time frame: Baseline and up to 2 hours post-intervention
