Diabetes-specific formula
Brief summary
Hypothesis: the diabetes-specific formula Nutren diabetes provides better postprandial glucose control in patients with type 2 diabetes when compared to the isocaloric diet.
Detailed description
This study is an open label, randomized controlled cross-over study Research objectives: 1. To study the efficacy of diabetes-specific formula (Nutren Diabetes) in comparison with an isocaloric diet in the aspect of postprandial blood glucose and insulin response (baseline, 30, 60 and 120 minute). 2. To study the safety and tolerance of a diabetes-specific formula compared with an isocaloric diet in patients with type 2 diabetes mellitus Statistical analysis method 1. Descriptive statistics: categorical data will be summarized as number and percentage, continuous data with normal distribution will be presented as means and standard deviations, and continuous data with non-normal distribution will be summarized as median, minimum and maximum. 2. Inferential statistics: Repeated Measure ANOVA from analyzing the difference of means from measuring fasting glucose and insulin more than two times. 3. Inferential statistics: Paired T-Test or Wilcoxon Matched pairs Signed Rank Test derived by analyzing the comparison between the means of two dependent groups. 4. Report of the difference between two categories by the difference of means with 95% Confidence Interval 5. Number of participant (subjects) and criteria for participation 30 participants by calculation formula of Frison and Pocock (1992) with STATA program.

Intervention model description
This is an open-label, randomized cross-over study. The study date will be 1 day for group A and 1 day for group B, separated by 7-day wash out period. The tolerability of DSF, assessed by questionnaire, will be collected while the subjects consume DSFs daily 7 days before the study date (only group A). The questionnaire will ask about gastrointestinal symptom including abdominal distention, nausea, vomiting, and stool frequency. Group A participants will be asked to drink 360 ml of Nutren Diabetes which provides 360 kcal. Group B participants will be asked to consume isocaloric diet (360 kcal)comprising one carton of soy milk (250 ml) and bologna and mayonnaise sandwiches (two slices of bread). Plasma glucose and insulin will be collected at baseline (minute 0) and 30, 60, 120 minute postprandially. The participants will be asked to complete the questionnaire (Visual analog scale) to assess hunger and satiety at minute 0, 30, 60 and 120 minute.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 2-hour postprandial glucose | Change form baseline blood glucose level at 30,60, and 120 min. | The primary outcome will be the difference of 2-hour postprandial glucose between group A and group B |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Area under the curve of postprandial plasma glucose (AUC glucose 0-120 min) | Time Frame: Postprandial blood glucose response at 0, 30, 60,120 min | The secondary outcome will be the difference of AUC glucose 0-120 min between group A and group B. Blood samples will be collected to assess plasma glucose at baseline and 30, 60, 120-minute postprandial. We will calculate the area under the curve of plasma glucose of patients in each arm at baseline and, 30, 60, 120 minute postprandial (AUC glucose 0-120 min) . Blood samples will be collected to assess plasma insulin at baseline and 30, 60, 120-minute postprandial. We will calculate the area under the curve of plasma insulin of patients in each arm at baseline and, 30, 60, 120 minute postprandial (AUC insulin 0-120 min) . |
| Area under the curve of postprandial plasma insulin (AUC insulin 0-120 min) | Postprandial plasma insulin response at 0, 30, 60,120 min | The secondary outcome will be the difference of AUC insulin 0-120 min between group A and group B. |
| Gastrointestinal tolerance | 7 days prior to the treatment phase. | Gastrointestinal tolerance including abdominal distention, nausea, vomiting, and stool frequency will be assessed by questionnaire. We will collect the symptom of GI tolerance everyday during the period that the patient consumes Nutren diabetes and isocaloric diet (7 days before the study date; only participants in group A ) |
