Summary

The blood glucose and plasma insulin responses to test milk samples were studied in healthy normal volunteers. After an overnight fast the subjects were given 500 ml of either regular fat free milk (∼ 25 g lactose) or 500 ml of a new low-lactose fat free milk (3.75 g lactose and 4.25 g fructose). Blood glucose levels were not significantly altered after either milk sample, but plasma insulin responses were significantly elevated after milk consumption. The response was slightly but not significantly higher after regular fat-free milk than after the low-lactose fat free milk. The results suggest that fat free milk does not exert a fast effect on blood glucose concentration and therefore fat free milk and especially low-lactose fat free milk may prove to be suitable for diabetic diets.

Zusammenfassung

An gesunden freiwilligen Versuchspersonen wurde die Reaktion des Blutglukosespiegels und der Plasmainsulinkonzentration auf Test-Milchproben untersucht. Nach Fasten über Nacht bekamen die Versuchspersonen 500 ml einer gewöhnlichen fettfreien Milch (ca. 25 g Laktose) oder 500 ml einer neuen laktosearmen, fettfreien Milch (3,75 g Laktose und 4,25 g Fruktose). Die Blutglukosespiegel wurden durch keine der beiden Milchproben signifikant erhöht, aber die Plasmainsulinkonzentration erhöhte sich nach der Milchzufuhr signifikant. Diese Reaktion war nach der gewöhnlichen fettfreien Milch geringfügig, aber nicht signifikant höher als nach der neuen laktosearmen, fettfreien Milch. Die Ergebnisse zeigen, daß fettfreie Milch keine rasche Wirkung auf die Konzentration der Blutglukose ausübt und daß deshalb fettfreie Milch, insbesondere solche mit geringem Laktosegehalt, auch für die Diabetesdiät geeignet ist.
