Comparative Evaluation of Glycemic Index of Different Types of Jaggery Produced Locally in Pakistan

June 3, 2025 updated by: Naseer Ahmed, Rehman Medical Institute - RMI
This study aims to evaluate and compare the glycemic index (GI) of various types of jaggery by measuring their effect on blood glucose levels in healthy individuals. Using glucose as the reference standard , the objective is to determine how different jaggery types influence postprandial blood sugar response.

Detailed Description

This study aims to evaluate and compare the glycemic index (GI) of various types of jaggery by measuring their effect on blood glucose levels in healthy individuals. Using glucose as the reference standard , the objective is to determine how different jaggery types influence postprandial blood sugar response. The findings will help identify which types of jaggery have lower glycemic impact, contributing to better dietary choices for glycemic control.

Eligibility Criteria

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:Participants should be clinically healthy, as determined by their medical records and verbal history. Only individuals with normal fasting blood glucose levels (70-99 mg/dL) during screening will be eligible -

Exclusion Criteria:1) Participants must not have any chronic disease, not be taking any medications that influence carbohydrate metabolism (such as corticosteroids or metformin), and should be non-smokers and non-alcoholics.

2) Pregnant or lactating female participants, as well as any person with gastrointestinal, metabolic, or endocrine disease (e.g., thyroid disease, PCOS, IBD), will be excluded.

3) Also, subjects with a history of recent acute illness (within the last 2 weeks) will be deferred.

Design Details

  • Primary Purpose: Prevention
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Single group (cross over)
Participants will receive all test interventions (2 different varieties of jaggery and a glucose reference) in a randomized sequence with appropriate washout periods between each session. Blood glucose levels will be measured after each test food to determine and compare glycemic index values.
Other: Golden sugarcane jaggery
Participants will consume a standardized portion of jaggery Type A providing 50 grams of available carbohydrates. Capillary blood glucose will be measured over a 2-hour postprandial period.
Other: Dark brown sugarcane jaggery
Participants will consume a standardized portion of jaggery Type B providing 50 grams of available carbohydrates. Capillary blood glucose will be measured over a 2-hour postprandial period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Glycemic Index (GI) of Different Types of Jaggery
Time Frame: Measured at multiple time points post-consumption (e.g., 0, 15, 30, 45, 60, 90, and 120 minutes) during each test session.
The incremental area under the blood glucose response curve (iAUC) over 2 hours after consumption of each type of jaggery, expressed as a percentage of the glucose reference.
Measured at multiple time points post-consumption (e.g., 0, 15, 30, 45, 60, 90, and 120 minutes) during each test session.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postprandial Blood Glucose Response Curve
Time Frame: Same as primary outcome (0-120 minutes).
Blood glucose levels at each time point following consumption of jaggery types and glucose, to assess the shape and peak of glycemic response.
Same as primary outcome (0-120 minutes).
