About this study

Official title: Chronic Effects of Ice Cream Enriched With Cimarrón Bean Extrudate on Metabolic and Cardiovascular Risk Markers: A Randomized Crossover Clinical Trial in Adults

The goal of this clinical trial is to evaluate the chronic effects of consuming a functional ice cream enriched with Cimarrón bean (Phaseolus vulgaris local variety Cimarrón) extrudate in adults with at least one cardiovascular risk factor.

The main question it aims to answer is:

Read more
  • Does chronic daily consumption of the functional ice cream with Cimarrón bean extrudate improve fasting glucose, insulin, lipid profile, and other cardiovascular risk markers?

Researchers will compare a functional ice cream containing 10 g of extrudate per100 g to a placebo version without extrudate, using a crossover design in which participants consume both versions for 4 weeks each, separated by a 3-week washout period to determine metabolic responses.

Participants will:

  • Attend clinical visits in fasting conditions at the beginning and end of each 4-week intervention to provide blood samples for glucose, insuli, lipid profile, complete blood count plus Erythrocyte sedimentation rate and HbA1c assessment.
  • Undergo anthroprometric measurements and blood pressure assessment at the beginning and end of each 4-week intervention.
  • Consume 100g/day of the assigned ice cream during each phase (Two phases)
Read the detailed description

This randomized, single-blind, crossover clinical trial assesses the effects of daily consumption of a functional ice cream enriched with Cimarrón bean extrudate (Phaseolus vulgaris L., local variety Cimarrón) extrudate in adults with at least one cardiovascular risk factor.

Eligible participants are adults (20-59 years) health or present at least one cardiovascular risk factor (e.g., smoking, insulin resistance, overweight/obesity, hypertension) and a BMI between 18.5 and 39.9 kg/m^2.

Participants are randomized into two groups (Alfa and Gamma) to receive either the placebo or functional ice cream first. Each intervention period lasts 4 week during which participants consume 100 g/day of the assigned ice cream (two 50 g portions, ~2 hours after a main meal). Following a 3-week washout period, participants switch to the alternate intervention. At the beginning and end of each intervention period, anthropometric assessments are performed, including body weight, height, body mass index (BMI), waist circumference, and mid-upper arm circumference. Additionally, fasting blood samples are collected to assess glucose, insulin, lipid profile, complete blood count plus erythrocyte sedimentation rate, HbA1c, and blood pressure.

The placebo or functional ice cream are organoleptically identical to ensure blinding. Randomization is stratified by sex, age, and BMI using balanced block randomization with R software (v4.5.0).

The primary outcomes are the within-subject changes in serum glucose and serum insulin concentrations between the intervention and placebo phases.

The Secondary outcomes include within-subject changes in:

  • Lipid profile parameters: total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, and the total cholesterol/HDL-c ratio.
  • Anthropometric measurements: body weight, waist circumference, arm circumference, and body mass index (BMI).
  • Blood pressure: systolic and diastolic, measured after rest.

Other Pre-specified Outcomes Glycemic control: Hemoglobin A1c (HbA1c).

  • Liver and kidney function markers: including serum aspartate aminotransferase (AST), creatinine, and urea.
  • Coagulation marker: Prothrombin time (PT).
  • Complete blood count (CBC): including hemoglobin, white blood cell count, red blood cell count, and platelet count.
  • Monitor systemic inflammatory status: Erythrocyte sedimentation rate (ESR)
  • Adherence to the intervention (measured by portion tracking and consumption logs).
  • Gastrointestinal symptom frequency (assessed via participant questionnaires).
  • Product acceptability and palatability (evaluated using Likert-scale surveys).
  • Participant-reported adverse events (monitored continuously throughout the intervention).

Model description
This is a randomized, single-blind, crossover clinical trial with two arms: one receiving a functional ice cream enriched with 10 g of Cimarrón bean extrudate (intervention) and one receiving a placebo ice cream (control), both matched for appearance and taste. Participants are randomly assigned to one of two groups (Alfa or Gamma). Each participant undergoes two intervention phases, each lasting four weeks, separated by washout period. The order of receiving the intervention or placebo is randomized. During each intervention period, participants consume 100 g/day of the assigned ice cream. Fasting blood samples and anthropometric data are collected at the beginning and end of each phase. Randomization is performed using block randomization stratified by sex, age, and body mass index (BMI), to ensure balance across treatment sequences. This crossover model allows each participant to serve as their own control, reducing inter-individual variability and increasing statistical power
