Dextrose (glucose) serves as a reference substance in the system glycemic index (GI) and is normative with the value 100 defined. The GI describes how strongly and how quickly carbohydrate-containing foods affect the body blood sugar level compared to pure glucose.
What is the Glycemic Index?
The Glycemic index (GI) is a classification system for evaluating the blood sugar effect of carbohydrates. Pure glucose (dextrose) With a GI of 100, it forms the reference size. Other foods are ranked relative to this value.
The GI refers to a standardized amount of available carbohydrates and describes the speed of the blood glucose response.
Glycemic index comparison
| Carbohydrate source | Typical GI value | Classification |
|---|---|---|
| Dextrose (glucose) | 100 | Reference value |
| Maltodextrin | 85–105 | high |
| Sucrose | approx. 65 | medium |
| Fructose | approx. 20 | low |
Glycemic index vs. glycemic load
While the GI the speed of the blood sugar increase describes, takes into account the glycemic load (GL) Additionally, the amount of carbohydrates actually consumed. For the practical evaluation of a meal, the combination of GI and portion size is often crucial.
Factors influencing blood sugar response
- Nutrient combination: Fats and proteins can slow stomach emptying.
- Degree of processing: Finely ground or heavily processed products are absorbed more quickly.
- Fiber: May delay glucose absorption.
- Individual metabolic situation: Insulin sensitivity, activity level and hormonal status influence the response.
Classification of dextrose in the GI system
There Dextrose chemically identical to that measured in blood Glucose is, it serves as a scientific reference value for the evaluation of other carbohydrates. The GI describes a standardized test condition and does not replace an individual metabolic assessment.
