OBJECTIVE Foods with contrasting glycemic index when incorporated into a meal, are able to differentially modify glycemia and insulinemia. However, little is known about whether this is dependent on the size of the meal. The purposes of this study were: i) to determine if the differential impact on blood glucose and insulin responses induced by contrasting GI foods is similar when provided in m...

BACKGROUND A chemically based classification of dietary carbohydrates that takes into account the likely site, rate, and extent of digestion is presented. The classification divides dietary carbohydrates into sugars, starch fractions, and nonstarch polysaccharides, and groups them into rapidly available glucose (RAG) and slowly available glucose (SAG) as to the amounts of glucose (from sugar an...

The Glycemic Index (GI) is a classification scheme based on the blood glucose rise after consuming a carbohydrate food. This measure is based on the absorption profile of the food and was originally considered an indirect, but adequate measure of the insulin response to food. The assumption was that the insulin rise would be proportional to the glucose rise. However, recent research has demonst...

The relative glycemic impact (RGI), the weight of glucose that would induce a glycemic response equivalent to that induced by a given amount of food, is preferably expressed for reference amounts of foods customarily consumed per eating occasion. But because customarily consumed portions of different foods deliver different glycemic carbohydrate doses, methods for determining their RGI need to ...

The Glycemic Index (GI) is intended to quantitatively rank carbohydrate based on its impact on blood glucose levels (1). It is a measurement of blood glucose response (over two hours) after ingesting a test food that typically contains 50 grams of glycemic carbohydrate. This value is then expressed as a percentage of the response to 50 grams of glycemic carbohydrate from either white bread or g...

Interest in the glycemic impact of diet on health and well-being is growing among health care professionals and consumers. Diets with high glycemic impact have been postulated to increase risk of obesity, insulin resistance, diabetes, and cardiovascular disease. A reduction in the glycemic impact of the diet has been proposed as a means of assisting body weight management, improving blood gluco...

OBJECTIVE Evaluate the influence of the glycemic index (GI) and glycemic load (GL) of the diet in the glycemic control of children and teenagers with type 1 diabetes mellitus (DM1). METHODS A total of 146 subjects, aged 7-19 years, monitored at the Division of Pediatric Endocrinology at the HC/UFMG participated in the study. The consumed diet was evaluated using a quantitative food frequency ...

BACKGROUND AND OBJECTIVES The glycemic response to commonly eaten fruits in Nigeria has not been reported. Therefore, this study assessed the plasma glucose response to selected fruits in Nigeria. PATIENTS AND METHODS Ten normal glucose-tolerant subjects randomly consumed 50 g carbohydrate portions of three fruits: banana (Musa paradisiaca), pineapple (Ananus comosus), and pawpaw (Carica papa...
