Brief summary

This study aims to evaluate and compare the glycemic load (GL) and glycemic index (GI) of different types of watermelons commonly available in the market. Using glucose as the reference standard, the study will measure the blood glucose response following consumption of each watermelon type in healthy adult participants.

Detailed description

his study aims to evaluate and compare the glycemic load (GL) and glycemic index (GI) of different types of watermelons commonly available in the market. Using glucose as the reference standard, the study will measure the blood glucose response following consumption of each watermelon type in healthy adult participants. The objective is to identify variations in glycemic impact among watermelon varieties to inform dietary recommendations for blood sugar management.

Interventions

OTHERWater melon (sugar baby)

Participants will consume a portion of watermelon Type A containing 50 grams of available carbohydrate to evaluate its glycemic index and glycemic load.

OTHERwatermelon (Charleston gray)

Participants will consume a portion of watermelon Type B containing 50 grams of available carbohydrate to evaluate its glycemic index and glycemic load.

OTHERwatermelon (Crimson sweet)

Participants will consume a portion of watermelon Type C containing 50 grams of available carbohydrate to evaluate its glycemic index and glycemic load.

Design outcomes

Primary

Measure	Time frame	Description
Glycemic Index (GI) of Watermelon Varieties	1 month	Description: Incremental area under the blood glucose response curve (iAUC) over 120 minutes after consuming each watermelon type, expressed as a percentage of the iAUC after consuming the glucose reference.

Secondary

Measure	Time frame	Description
Glycemic Load (GL) of Watermelon Varieties	1 month	Calculated using the formula: Glycemic Load = (GI × carbohydrate content per typical serving) ÷ 100
