Abstract

Previous studies have found a small association between the level of blood glucose and subjective reports of energy in those sitting quietly. Given reports that both memory and attention are influenced by the level of blood glucose it was hypothesised that under conditions of cognitive demand there would be a stronger association between mood and blood glucose levels. In three studies, with three cognitive tasks, the Stroop Task, Rapid Information Processing Task, and a difficult test of hand-eye coordination, falling blood glucose was associated with feeling less energetic.
