Sugary breakfast foods slows children’s brains Children who miss proper breakfasts or who eat sugary snacks may end up with slower reaction times. Foods containing complex carbohydrates break down slowly providing energy throughout the morning. Sugary snacks contain simple sugars which are used up very quickly and children are then more likely to lose concentration and be tempted to eat more sugary snacks. Researchers have shown that two hours after eating a sugary snack, the children have a similar reaction time to a 70 year old. Stefan is worried because he always misses breakfast.
