OBJECTIVE We sought to assess the intra- and interindividual variability of glycemic index value determinations for white bread using glucose as the reference food. RESEARCH DESIGN AND METHODS A total of 23 healthy adults (aged 20-70 years) completed up to three sets of two visits per set. Each pair of visits assessed the glycemic response to 50 g available carbohydrates from commercial white...

Sugars have a long history of safe use in foods. Placed on the Food and Drug Administration’s list of foods that are ‘‘generally recognized as safe’’ in 1958, sugars and the health aspects of sugar consumption continue to be evaluated. Recent research has focused on several potential sugars and health relationships, sugar consumption and nutritional quality of the diet, recommendations for suga...

BACKGROUND Although the associations of dietary glycemic index (GI) and dietary glycemic load (GL) with many chronic diseases have been examined in epidemiologic studies, information regarding the reproducibility and validity of these measures assessed with the use of food-frequency questionnaires (FFQs) is lacking. OBJECTIVE We examined the reproducibility and validity of dietary GI and diet...

OBJECTIVE To determine the association of insulin sensitivity and pancreatic beta-cell function parameters assessed by the homeostasis model assessment (HOMA) and glycemic control, and their potential utilization in the clinical care of patients with type 2 diabetes mellitus. MATERIAL AND METHOD The HOMA indices were assessed in 204 (62 males, 142 females) type 2 diabetic outpatients aged 60....

We aimed to prospectively examine the association between the glycemic index and glycemic load of foods consumed and the dietary intakes of carbohydrates, sugars, fiber, and principal carbohydrate-containing food groups (eg, breads, cereals, and sugary drinks) with changes in blood pressure during adolescence. A total of 858 students aged 12 years at baseline (422 girls and 436 boys) were exami...

The conventional glycemic indices used in management of diabetic patients includes A1c, fructosamine, 1,5-anhydroglucitol, and glycated albumin (GA). Among these indices, A1c is currently used as the gold standard. However, A1c cannot reflect the glycemic change over a relatively short period of time, and its accuracy is known to decrease when abnormalities in hemoglobin metabolism, such as ane...
