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 .
The influence on cognition of the interaction between the macro-nutrient content of breakfast and glucose tolerance
Previously it has been found that both missing breakfast and having poorer glucose tolerance were associated with better memory . The present study therefore examined the impact of eight breakfasts , in a factorial design , that contained either high or low levels of carbohydrate , fat or protein . The meals were design ed to vary the rate of release of glucose into the blood stream . Memory , reaction times and vigilance were assessed 30 , 75 and 120 min following breakfast . Using fasting blood glucose levels as a measure of glucose tolerance , better memory was found to be associated with better glucose tolerance and the consumption of meals that more slowly release glucose into the blood . The effects of the meals on reaction times and vigilance were opposite to those with memory in that higher levels of blood glucose tended to be associated with better performance . It was concluded that individual differences in glucose tolerance interact with the glycaemic load of a meal to influence cognitive functioning
