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 .
Blood glucose influences memory and attention in young adults
There is evidence from animal studies that increased blood glucose levels are associated with improved memory and attention . Although previous studies have found human memory to be facilitated by the administration of glucose , attentional measures have been largely ignored . Therefore the impact of a glucose drink , or a placebo , on the Rapid Information Processing Task and the Stroop Task was examined . The reaction times of those taking the Rapid Information Processing Task were faster both during the baseline period and after a glucose drink if the blood glucose values were high . With the  Stroop task  the ability to perform the most cognitively dem and ing sub-test was selectively enhanced if blood glucose values were increasing prior to starting the test . The ability to recall words from a word list was greater if a glucose drink had been consumed , although primary and recency were not differentially influenced . The possibility is discussed that higher levels of brain glucose are associated with better memory and attention
