“…This finding appears to be in concordance with previous work in the literature in which increased blood glucose concentration has been associated with enhanced response times Owens and Benton 1994). The current study finding that glucose ingestion improves response times during a recognition memory task extends previous work from our laboratory which suggests that the glucose memory facilitation effect can be generalised to healthy adolescents (Smith and Foster 2008a;Smith and Foster 2008b).…”

“…An 'inverted U'-shaped dose-response curve was reported for the effects of plasma glucose [35], and insulin concentration [36] on cognitive functions. It is likely that the ascending or descending part of an 'inverted U' relation represents the acute positive and negative effects of a rise or fall [37,38] in blood glucose concentration on specific cognitive functions. However, constant metabolic conditions [39] might optimize overall cognitive performance [34,27] for a longer time period.…”

Background: The high protein (HP) breakfast reduced gastric emptying and the most satiating macronutrient appears to be dietary protein.Few studies have investigated the effects of protein to energy ratio in breakfast on mood, alertness and attention. Objective: This study was designed to investigate whether the HP breakfast is more beneficial to mood, alertness and attention of the healthy undergraduate student than adequate-protein (AP) breakfast through the rising body temperature and remaining stable blood glucose or through other physiologic processes. Methods: Thirteen healthy male undergraduate students (18 -23 y) were studied in a double-blind, randomized crossover design. Blood samples, body temperature, satiety, mood and Continuous Performance Test (CPT) were assessed after the consumption of two isocaloric breakfasts that differed in their protein and carbohydrate content: an HP breakfast (50%, 30%, and 20% of energy from protein, carbohydrate, and fat, respectively) or an AP breakfast (10%, 70%, and 20% of energy from protein, carbohydrate, and fat, respectively). Results: Consumption of an HP breakfast resulted in more steady glucose and insulin than AP breakfast consumption (p < 0.05). Satiety scores and body temperature were higher after HP breakfast consumption (p < 0.05). And most important, the positive mood and CPT scores were higher after HP breakfast than after AP breakfast intake (p < 0.05). Conclusion: HP breakfast can effectively stabilize postprandial serum glucose concentration and elevate postprandial temperature of healthy male undergraduate students. Our present findings demonstrate the relationship between HP breakfast and mood, alertness and attention. This study indicated that HP breakfast may enhance human performance probably by increasing the thermic effect of a food and elevating body temperature.

The brain relies upon glucose as its primary fuel. In recent years, a rich literature has developed from both human and animal studies indicating that increases in circulating blood glucose can facilitate cognitive functioning. This phenomenon has been termed the 'glucose memory facilitation effect'. The purpose of this review is to discuss a number of salient studies which have investigated the influence of glucose ingestion on neurocognitive performance in individuals with a) compromised neurocognitive capacity, as well as b) normally functioning individuals (with a focus on research conducted with human participants). The proposed neurocognitive mechanisms purported to underlie the modulatory effect of glucose on neurocognitive performance will also be considered. Many theories have focussed upon the hippocampus, given that this brain region is heavily implicated in learning and memory. Further, it will be suggested that glucose is a possible mechanism underlying the phenomenon that enhanced memory performance is typically observed for emotionally laden stimuli.
