About

The object of this study is to compare "100g Standard Noodles " with traditional carbohydrates including 75g glucose solution in 300ml water and 100g steamed bread in the diagnosis of diabetes mellitus.

In this study, we will compare the different effects of "100g Standard Noodles Tolerance Test"and "75g Oral Glucose Tolerance Test"on plasma glucose, insulin, c- peptide level and the relevant hormones level including glucagon-like peptide-1( GLP-1) and glucagon. Besides, in part of the subjects, the difference between "100g Steamed Bread Tolerance Test", "100g Standard Noodles Tolerance Test" and "75g Oral Glucose Tolerance Test" will be further evaluated.

Enrollment: 240 estimated patients

Ages: 16 to 70 years old
