Students who eat a low-glycemic, balanced breakfast may have better concentration and more positive reactions to difficult tasks than students who eat a carbohydrate-laden breakfast. According to research published in “Physiology and Behavior," students given a low-glycemic breakfast were able to sustain attention longer than children given a high-glycemic breakfast. Children following the low-glycemic breakfast plan also had improved memory and fewer signs of frustration when working on school tasks. Try old-fashioned oatmeal with a handful of walnuts or some scrambled eggs with spinach, peppers and a sprinkle of cheese.
