Introduction: Type 2 diabetes mellitus is deficiency of insulin and caused by decreases of insulin receptor or bad quality of insulin. As a result, insulin hormone does not work effectively in blood glucose regulation. String bean juice contains thiamin and fiber may regulate blood glucose level. The aim of this study was to analyze the effect of string bean juice to decrease blood glucose level of patients with type 2 diabetes mellitus.

Method: This study employed a quasy-experimental pre-post test control group design and purposive sampling.  The population were all type 2 diabetes mellitus patients in Puskesmas Pacar Keling Surabaya. Sample were 12 patients who met inclusion criteria. The independent variable was string bean juice and dependent variable was blood glucose level. Data were analyzed by using Paired T-test with significance level of α≤ 0.05 and Independent T-test with significant level of α≤0.05.

Result: The results showed that string bean juice has an effect on decreasing blood glucose between pre test and post test for blood glucose with independent T-test is p=0.003.In conclusion, string bean juice has an effect on blood glucose level in patients with type 2 diabetes mellitus.

Discussion: The possible explanation for this findings is string bean juice contains two ingredients: thiamine and fiber. Thiamine helps support insulin receptors and glucose transporter in cells hence GLUT-4 could translocated to the cell membrane brought glucouse enter to the  intracellular compartment, that leads to blood glucouse level well regulated.  Dietary fiber reduces food transit time so slowing the glucose absorption. Therefore blood glucose level will be decreased.
