This study aims to evaluate the effect of different peach varieties on the glycemic index (GI) in healthy adult participants. While peaches are generally classified as low-GI fruits, variations in sugar composition, fiber content, and ripeness among different cultivars may influence their glycemic response. By assessing and comparing the GI values of several commonly consumed peach varieties, this trial seeks to provide more precise dietary recommendations for glycemic control and support better fruit selection for individuals managing blood glucose levels.
BMI between 18.5-24.9 kg/m²
Normal fasting blood glucose (<100 mg/dL)
Willingness to adhere to the study protocol
Use of medications or supplements that affect glucose levels
Allergy to peaches or intolerance to test/reference foods
Pregnant or breastfeeding women
Smoking or use of recreational drugs
Single group
EARLY GRAND
Other interventionParticipants will consume a standardized portion of peach variety A containing 50 grams of available carbohydrates. Capillary blood glucose levels will be measured at multiple time points post-consumption to assess glycemic response.
SPRING CREST PEACH
Other interventionParticipants will consume a standardized portion of peach variety B containing 50 grams of available carbohydrates. Capillary blood glucose levels will be measured at multiple time points post-consumption to assess glycemic response.
INDIAN BLOOD
Other interventionParticipants will consume a standardized portion of peach variety C containing 50 grams of available carbohydrates. Capillary blood glucose levels will be measured at multiple time points post-consumption to assess glycemic response.
Glycemic Index
Participants will consume a standardized portion of a peach variety containing 50 grams of available carbohydrates. Capillary blood glucose levels will be measured at multiple time points post-consumption to assess glycemic response.
Incremental Area Under the Curve (iAUC) for Blood Glucose
The iAUC will be calculated for each intervention using the trapezoidal method, excluding values below baseline. This helps quantify the glycemic response.
Peak Blood Glucose Concentration
The highest recorded blood glucose concentration during the 2-hour postprandial period following consumption of each intervention.
