Glycemic impact, defined as "the weight of glucose that would induce a glycemic response equivalent to that induced by a given amount of food" (American Association of Cereal Chemists Glycemic Carbohydrate Definition Committee, 2007), expresses relative glycemic potential in grams of glycemic glucose equivalents (GGEs) per specified amount of food. Therefore, GGE behaves as a food component, an...

This study aimed to investigate the influence of acute glycemic load on vascular endothelial function in patients with hypertension and to evaluate the protective effect of vitamins C and E during the acute glycemic phase. We randomly selected 39 hypertensive patients and 21 normal subjects and divided them into 3 groups: 75 g oral glucose (glycemic load group), 75 g glucose+0.9 g vitamin C (VC...

OBJECTIVE To systematically tabulate published and unpublished sources of reliable glycemic index (GI) values. RESEARCH DESIGN AND METHODS A literature search identified 205 articles published between 1981 and 2007. Unpublished data were also included where the data quality could be verified. The data were separated into two lists: the first representing more precise data derived from testing...

CONTEXT Carbohydrate-restricted diets have been popular in recent years. The theoretical glycemic impact of these diets, compared with other popular weight-loss diets, has not been reported. OBJECTIVE To assess the glycemic index (GI) and glycemic load (GL) of 2 popular, carbohydrate-restricted diets (South Beach and Sugar Busters!) and compare them with a low-fat, high-carbohydrate diet (Orn...

Reliable tables of glycemic index (GI) compiled from the scientific literature are instrumental in improving the quality of research examining the relation between GI, glycemic load, and health. The GI has proven to be a more useful nutritional concept than is the chemical classification of carbohydrate (as simple or complex, as sugars or starches, or as available or unavailable), permitting ne...

OBJECTIVE Diets with high glycemic index (GI), with high glycemic load (GL), or high in all carbohydrates may predispose to higher blood glucose and insulin concentrations, glucose intolerance, and risk of type 2 diabetes. We aimed to conduct a systematic literature review and dose-response meta-analysis of evidence from prospective cohorts. RESEARCH DESIGN AND METHODS We searched the Cochran...

The possibility that high, long-term intake of carbohydrates that are rapidly absorbed as glucose may increase the risk of type 2 diabetes has been a long-standing controversy. Two main mechanisms have been hypothesized, one mediated by increases in insulin resistance and the other by pancreatic exhaustion as a result of the increased demand for insulin. During the past decade, several lines of...

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...

Many people believe that when they are diagnosed with Diabetes – Type 1 or Type 2 and even prediabetes that they can no longer enjoy eating food. Part of the reason that those diagnosed with diabetes feel this way is they are asked to consider the carbohydrate content, fat content, glycemic load, and potential impact on your weight of everything you eat. This can make it extremely difficult to ...

BACKGROUND Risk of thyroid cancer has already been related to refined cereals and starch food, but the association has not been studied in terms of glycemic index (GI) and glycemic load (GL). PATIENTS AND METHODS We analyzed data from a case-control study conducted in Italy from 1986 to 1992 and including 399 histologically confirmed and incident cases of thyroid cancer and 616 control subjec...
