Erythritol and blood sugar after meals in diabetic mice

What it found

In diabetic mice, erythritol lowered the rise in blood sugar after a dose of starch.

The authors say it likely works by blocking an enzyme that breaks starch down into sugar.

Blood sugar in mice

In diabetic mice, erythritol at 500 mg kg-1 lowered the rise in blood sugar after starch was given into the stomach.

How it may work

The authors found erythritol most likely acts by inhibiting the enzyme alpha-glucosidase in a competitive manner. This was supported by enzyme activity assays and molecular modeling.

Docking in the enzyme

In modeling experiments, erythritol docked into the catalytic pocket of alpha-glucosidase. The authors say the interaction was likely driven by electrostatic interactions involving Asp215, Asp69 and Arg446 residues.

What the authors conclude

“This study suggests that erythritol may not only serve as a glucose substitute but also be a useful agent in the treatment of DM to help manage postprandial blood glucose levels.”

Also in their conclusions

  • They suggest that erythritol may not only serve as a glucose substitute but also be a useful agent in the treatment of diabetes to help manage postprandial blood glucose levels.

How it was done

Diabetes is a serious metabolic disorder, and poor control of blood sugar after meals often leads to severe health complications. The authors wanted to see whether erythritol could play a role in controlling blood sugar after meals in diabetes.

They gave erythritol at 500 mg kg-1 to mice with alloxan-induced diabetes and tracked blood sugar changes after giving starch and drugs into the stomach. They also ran enzyme activity tests and molecular modeling experiments.
