Water Intake and Glycemic Response : Preliminary Study
December 4, 2015 updated by: Nutrifood Research Center, Jakarta, Indonesia
Glycemic index concept is widely used to determine impact of a food to blood glucose.
Several studies showed that water content and intake after meal may influence glycemic response of the meal and thus have an effect on the result of GI measurement.
Currently these studies found conflicting results.
Therefore, this study aims to determine whether water intake, specifically after meal, may influence the glycemic response and glycemic index value of the meal.

Experimental: Glucose Ref - Std
250 ml glucose solution with 50 gram available carbohydrate per serving, used as reference
|
First, fasting blood glucose was measured.
Then, subjects consumed the glucose sample in 5-10 minutes and blood sugar level were measured at 0', 15', 30', 45', 60', 90', and 120'
|
|
Experimental: Glucose Ref and 450 ml water
250 ml glucose solution with 50 gram available carbohydrate per serving.
Sample was consumed with additional water intake @150 ml at 45, 75, and 105 minutes after meal consumption
|
First, fasting blood glucose was measured.
Then, subjects consumed the glucose sample in 5-10 minutes.
Subjects given additional 150 ml water at 45, 75, and 105 minutes and blood sugar level were measured at 0', 15', 30', 45', 60', 90', and 120
|
|
Experimental: White Bread with 250 ml water
White bread with 50 gram available carbohydrate was consumed with 250 ml water immediately after meal consumption
|
First, fasting blood glucose was measured.
Then, subjects consumed the samples in 10-15 minutes and blood sugar level were measured at 0', 15', 30', 45', 60', 90', and 120'
|
|
Experimental: White Bread and 700 ml water
White bread with 50 gram available carbohydrate was consumed with 250 ml water immediately after meal consumption.
Moreover, subjects given additional water intake @150 ml at 45, 75, and 105 minutes after meal consumption
|
Sample consumed with 250 ml water immediately after meal consumption, and additional 150 ml water at 45, 75, and 105 minutes. First, fasting blood glucose was measured.

|
Experimental: White Bread with 125 ml water (twice)
Sample consumed with 125 ml water immediately after meal consumption, and additional 125 ml water after 60 minutes
|
Sample consumed with 125 ml water immediately after meal consumption, and additional 125 ml water after 60 minutes First, fasting blood glucose was measured. Then, subjects consumed the samples in 10-15 minutes and blood sugar level were measured at 0', 15', 30', 45', 60', 90', and 120' |

Measure Description |
Time Frame |
|---|---|---|
|
2 h postprandial blood glucose level (Glycemic Response)
Time Frame: fasting 0 min, 15 min, 30 min, 45 min, 60 min, 90 min, 120 min
|
fasting 0 min, 15 min, 30 min, 45 min, 60 min, 90 min, 120 min

|
Glycemic index value of meal (white bread)
Time Frame: fasting 0 min, 15 min, 30 min, 45 min, 60 min, 90 min, 120 min
|
The glycemic index is a calculated from measurements of area under the glucose curve after the food is eaten, divided by the corresponding area after the control food is eaten.
The value is multiplied by 100 to represent a percentage of the reference food.
