Bei DM gibt es solche isotonische Lösungen.

Maltodextrin wird langsamer resorbiert: Dadurch kommt es nicht wie beispielsweise bei Traubenzucker zu einem starken Blutzuckeranstieg, der im Körper eine kompensatorische, überschießende Insulinausschüttung bewirkt und so mittelfristig eher zu einer Unterzuckerung führt („Hungerast“)

Maltodextrin wird langsamer resorbiert

There has been a multi-phase research study conducted at the University of Memphis under the supervision of Dr. Richard Kreider, prior to his departure to Baylor University, that documents some of the benefits of honey in sport.

In the first phase7 of the study, honey was evaluated regarding its efficacy as a pre-workout energy source. Blood glucose, insulin concentration, glycemic index and the insulin response index were determined in seventy-one subjects. After an eight-hour fast, the subjects were given one of seven gel packets. The packets contained either dextrose, sucrose, fructose, maltodextrin, honey, PowerGel (a commercially available gel product), or similarly flavored placebo. At the conclusion of the study, the investigators found that dextrose, sucrose, maltodextrin, honey and PowerGel significantly increased blood glucose levels following ingestion although honey had the lowest glycemic index response. When ranked in order from lowest to highest, the glycemic index of each gel was:

Fructose 5
Honey 35
PowerGel 43
Sucrose 71
Dextrose 100
Maltodextrin 121

Another finding from this first phase was that the insulin response (insulin response index or IRI) of honey was relatively low. Comparisons between the gel groups showed that maltodextrin has the highest, or fastest, IRI. When ranked from lowest to highest, the IRI for the gels were:

Fructose 41
Honey 59
Dextrose 100
PowerGel 113
Sucrose 147
Maltodextrin 158
