In summary , GI breakfasts do not affect cognitive domains in children and adolescents
This systematic review and meta- analysis aims to compare the effect of High-Glycemic Index ( GI ) versus Low-GI breakfasts on cognitive functions , including memory and attention , of children and adolescents .
Glucose facilitation of cognitive performance in healthy young adults: examination of the influence of fast-duration, time of day and pre-consumption plasma glucose levels
Abstract . Rationale : Previous investigations have demonstrated increased performance after the administration of a glucose-load on certain aspects of cognitive functioning in healthy young adults . Generally these studies have used a procedure where participants were tested in the morning after an overnight fast . Objective : The aim of the present study was , for the first time , to investigate the glucose cognitive facilitation effect under more natural testing times and with shorter duration of the previous fast . Methods : Measures of verbal and non-verbal memory performance were compared under different fasting intervals ( 2-h fast versus overnight fast ) , times ( morning versus afternoon ) and glycaemic conditions ( glucose versus aspartame drinks ) in healthy young participants . Results : There was a significant glucose facilitation effect on long-term verbal memory performance . In addition , glucose significantly enhanced long-term spatial memory performance . The effect of glucose was essentially equivalent whether it was given after an overnight fast or a 2-h fast following breakfast or lunch . There was no effect of drink and time of day on working memory performance . Conclusions : The results of this study further support the hypothesis that glucose administration can enhance certain aspects of memory performance in healthy young adults . More significantly , the findings indicate that this cognitive facilitation effect persists under more naturalistic conditions of glucose administration and is not restricted to long fast duration s or morning administration
