Details and patient eligibility

About

Food intake has a great influence on blood glucose of patients with diabetes. This study was designed to determine the glycemic index (GI) of a particular pomelo named Majia pomelo and its effects on postprandial glucose (PPG) excursions in both healthy subjects and patients with type 2 diabetes (T2DM).

Full description

The purpose of this study was to evaluate the GI and effects on glucose excursion of Majia pomelo in both healthy and diabetic subjects. The results may help diabetic subjects and their health care providers in developing a diet that is both medically and culturally appropriate.

59 participants in 4 patient groups

Diabetic
Other group
Description:
Diabetic patients use metformin or only on diet control(met or diet).18 of the patients were on metformin treatment and 2 patients were on diet control due to the early stage of this disease. On the first test day we utilized 50 g of glucose dissolved in 200 ml water. The second day was washout day. On the third day we used 922 g of Majia pomelos which contained 50 g carbohydrate.This group of diabetic patients enrolled for the case control period.
Treatment:
Drug: met or diet
Dietary Supplement: Glucose
Dietary Supplement: Pomelo
Healthy
Other group
Description:
On the first test day we utilized 50 g of glucose dissolved in 200 ml water. The second day was washout day. On the third day we used 922 g of Majia pomelos which contained 50 g carbohydrate.This group of volunteers enrolled for the case control period.
Treatment:
Dietary Supplement: Glucose
Dietary Supplement: Pomelo
Diabetic 2 - without pomelo
Other group
Description:
Patients of Diabetic 2 group were on CSII treatment with insulin subcutaneous pump.The scheme and dose of CSII for each patients were adjusted on the first 3 test days to optimize glucose control, followed by 3-day CSII treatment without change of insulin dose. On the 7th test day, patients consumed 100g Majia pomelos after meals (breakfast, lunch and dinner) for 3 test days. This arm refers to the group on the 4th to 6th day with a constant dose of insulin and did not consumed Majia pomelos after meals, and this intervention was defined as blank.
Treatment:
Drug: Insulin
Other: Blank
Diabetic 2 - with pomelo
Other group
Description:
Patients of Diabetic 2 group were on CSII treatment with insulin subcutaneous pump.The scheme and dose of CSII for each patients were adjusted on the first 3 test days to optimize glucose control, followed by 3-day CSII treatment without change of insulin dose. On the 7th test day, patients consumed 100g Majia pomelos after meals (breakfast, lunch and dinner) for 3 test days. This arm refers to the group on the 7th to 9th day with a constant dose of insulin and consumed 100g Majia pomelos after meals (breakfast, lunch and dinner).
Treatment:
Drug: Insulin
Dietary Supplement: Pomelo
