Breakfast reduces declines in attention and memory over the morning in schoolchildren
Twenty-nine schoolchildren were tested throughout the morning on 4 successive days , having a different breakfast each day ( either of the cereals Cheerios or Shreddies , glucose drink or No breakfast ) . A series of computerised tests of attention , working memory and episodic secondary memory was conducted prior to breakfast and again 30 , 90 , 150 and 210 min later . The glucose drink and No breakfast conditions were followed by declines in attention and memory , but the declines were significantly reduced in the two cereal conditions . This study provides objective evidence that a typical breakfast of cereal rich in complex carbohydrates can help maintain mental performance over the morning
