Brief summary
The aim of this study is develop recipes containing CHO less than ICR, prepare new snacks alternatives that could be consumed without need for additional insulin doses, and evaluate the glycemic and insulinemic responses of these recipes. A randomized crossover trial will include 15 healthy adults aged 19-30 years. All participants will consume 3 test foods and reference food (glucose solution, 2 times) in a random order. Blood samples will be collected at time points 0,15, 30, 45, 60, 90 and 120 min. Glucose and insulin analyzes will be performed from blood samples. The results of these time points will be marked on the chart and the incremental area under the curve (iAUC) will be calculated for both glucose and insulin.
Interventions
OTHERBlueberry Cake
Blueberry cake containing 25 g available CHO will be served to the participants after 10-hours fasting and asked to consume it within 15 minutes, along with 250 ml of water. Taking the first bite from test food will be considered as 0 min. Blood samples will be collected at time points 0,15, 30, 45, 60, 90 and 120 min.
OTHERSnacks with Cheese
Snacks with cheese containing 25 g available CHO will be served to the participants after 10-hours fasting and asked to consume it within 15 minutes, along with 250 ml of water. Taking the first bite from test food will be considered as 0 min. Blood samples will be collected at time points 0,15, 30, 45, 60, 90 and 120 min.
OTHERSpicy Crackers
Spicy crackers containing 25 g available CHO will be served to the participants after 10-hours fasting and asked to consume it within 15 minutes, along with 250 ml of water. Taking the first bite from test food will be considered as 0 min. Blood samples will be collected at time points 0,15, 30, 45, 60, 90 and 120 min.
OTHERGlucose Solution First Repeat
The glucose solution will be prepared by dissolving 25 g of glucose in 250 ml of water. Participants consume the glucose solution within 15 minutes after 10-hours fasting. Blood samples will be collect at time points 0,15, 30, 45, 60, 90 and 120 min.
OTHERGlucose Solution Second Repeat
The glucose solution will be prepared by dissolving 25 g of glucose in 250 ml of water. Participants consume the glucose solution within 15 minutes after 10-hours fasting. Blood samples will be collect at time points 0,15, 30, 45, 60, 90 and 120 min.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postprandial glucose response | two hours postprandial period | Postprandial glucose response will be quantified as incremental area under the curve (iAUC) (mg/dL x minutes), which is calculated according to the trapezoidal rule by using blood glucose values at time points 0, 15, 30, 45, 60, 90, and 120 minutes. |
| Postprandial insulin response | two hours postprandial period | Postprandial insulin response will be quantified as incremental area under the curve (iAUC) (mg/dL x minutes), which is calculated according to the trapezoidal rule by using blood glucose values at time points 0, 15, 30, 45, 60, 90, and 120 minutes. |
