A favorite measure of dieters in the present times, what index indicates how quickly blood sugar levels rise after eating a particular type of food?
"limitation of the glycemic index is that it does not measure insulin production due to rises in blood sugar. As a result, two foods could have the same glycemic index, but produce different amounts of insulin. Likewise, two foods could have the same glycemic load, but cause different insulin responses. Furthermore, both the glycemic index and glycemic load measurements are defined by the carbohydrate content of food. For example, when eating steak, which has no carbohydrate content but provides a high protein intake, up to 50% of that protein can be converted to glucose when there is little to no"

Glucose has a glycemic index of 100, by definition, and other foods have lower glycemic index. Sucrose has a GI of 68, fructose is 24, and tagatose has very low GI compared with other sweeteners. High blood glucose levels or repeated glycemic ""spikes"" following a meal may promote type 2 diabetes by increasing systemic glycative stress other oxidative stress to the vasculature and also by the direct increase in insulin levels, while individuals who followed a low-GI diet over many years were at a"
"indices may be useful for dietary management and avoidance of non-insulin-dependent diabetes mellitus and hyperlipidemia. The Insulin Index is not the same as a glycemic index (GI), which is based exclusively on the digestible carbohydrate content of a food, and represents a comparison of foods in amounts with equal digestible carbohydrate content (typically 50 g). The insulin index compares foods in amounts with equal overall caloric content (250 kcal or 1000 kJ). Insulin indexes are scaled relative to white bread, while glycemic index scores nowadays are usually scaled with respect to pure glucose, although in the past white bread has"

A higher satiety score indicates how much less was eaten from a buffet after participants ate the listed food. Glucose (glycemic) and insulin scores were determined by feeding 1000 kilojoules (239 kilocalories) of the food to the participants and recording the area under the glucose/insulin curve for 120 minutes then dividing by the area under the glucose/insulin curve for white bread. The result being that all scores are relative to white bread. The satiety"

The clinical importance of the glycemic index is controversial, as foods with high fat contents slow the resorption of carbohydrates and lower the glycemic index, e.g. ice cream. An alternative indicator is the insulin index, measured as the impact of carbohydrate consumption on the blood insulin levels. The glycemic load is an indicator for the amount of glucose added to blood glucose levels after consumption, based on the glycemic index and the amount"

Foods with carbohydrates that break down quickly during digestion and release glucose rapidly into the bloodstream tend to have a high GI; foods with carbohydrates that break down more slowly, releasing glucose more gradually into the bloodstream, tend to have a low GI. The concept was developed by Dr. David J. Jenkins and colleagues in 1980–1981 at the University of Toronto in their research to find out which foods were best for people with diabetes. A lower glycemic index suggests slower rates of digestion and absorption of the foods' carbohydrates and can also"

Because some foods typically have a low carbohydrate content, Harvard researchers created the GL, which takes into account the amount of carbohydrates in a given serving of a food and so provides a more useful measure. Liu et al. were the first to show that based on their calculation, the glycemic load of a specific food—calculated as the product of that food's carbohydrate content and its glycemic index value—has direct physiologic meaning in that each unit can be interpreted as the equivalent of 1 g carbohydrate from white bread (or glucose depending"

The Insulin Index can be more useful than either the glycemic index or the glycemic load because certain foods (e.g., lean meats and proteins) cause an insulin response despite there being no carbohydrates present, and some foods cause a disproportionate insulin response relative to their carbohydrate load. Holt et al. have noted that the glucose and insulin scores of most foods are highly correlated, but high-protein foods and bakery products that are rich in fat and refined carbohydrates ""elicit insulin responses that were disproportionately higher than their glycemic responses.""

It compares available carbohydrates gram for gram in individual foods, providing a numerical, evidence-based index of postprandial (post-meal) glycemia. The concept was invented by Dr. David J.

Once identified, this can be improved by using a faster acting insulin, or injecting insulin 20 minutes before eating, or by selecting carbohydrates to eat that are slower to peak in the bloodstream.

The concept of the glycemic index was developed in 1981 by David Jenkins to account for variances in speed of digestion of different types of carbohydrates. This concept classifies foods according to the rapidity of their effect on blood sugar levelswith fast-digesting simple carbohydrates causing a sharper increase and slower-digesting complex carbohydrates, such as whole grains, a slower one.

"low-GI food will cause blood glucose levels to increase more slowly and steadily, which leads to more suitable postprandial (after meal) blood glucose readings. A high-GI food causes a more rapid rise in blood glucose level and is suitable for energy recovery after exercise or for a person experiencing hypoglycemia. The glycemic effect of foods depends on a number of factors, such as the type of starch (amylose versus amylopectin), physical entrapment of the starch molecules within the food, fat and protein content of the food and organic acids or their salts in the meal – adding vinegar, for example,"
"Postprandial glucose test A postprandial glucose test is a blood glucose test that determines the amount of a type of sugar, called glucose, in the blood after a meal. Glucose is mainly made from carbohydrate foods. It is the main source of energy used by the body. Normally, blood glucose levels increase slightly after eating. This increase causes the pancreas to release insulin, which assists the body in removing glucose from the blood and storing it for energy. People with diabetes may not produce or respond properly to insulin, which causes their blood glucose to remain elevated. Blood glucose levels"

However, others have pointed out that foods generally considered to be unhealthy can have a low glycemic index, for instance, chocolate cake (GI 38), ice cream (37), or pure fructose (19), whereas foods like potatoes and rice have GIs around 100 but are commonly eaten in some countries with low rates of diabetes.

Hamman and Hirschman first reported improvement of carbohydrate tolerance following repeated glucose administration in 1919. H. Staub in 1921 and K.

Despite widely variable intervals between meals or the occasional consumption of meals with a substantial carbohydrate load, human blood glucose levels tend to remain within the normal range. However, shortly after eating, the blood glucose level may rise, in non-diabetics, temporarily up to 7.8 mmol/L (140 mg/dL) or slightly more. For people with diabetes maintaining 'tight diabetes control', the American Diabetes Association recommends a post-meal glucose level of less than 10 mmol/L (180 mg/dL) and a fasting plasma glucose"

It is usually detected by accidental discovery of mildly elevated blood sugar (e.g., during pregnancy screening). An oral glucose tolerance test is much less abnormal than would be expected from the impaired (elevated) fasting blood sugar, since insulin secretion is usually normal once the glucose has exceeded the threshold for that specific variant of the glucokinase enzyme.
