Though the value of the first meal of the day cannot be overemphasized, what you actually have in that meal could make a major difference. A recent study showed that children had better memory skills (five to 12 percent better) after eating oatmeal for breakfast when compared to their performance after eating no breakfast. In addition, girls performed better on short-term memory tests after eating oatmeal than after eating ready-to-eat cereal or no breakfast at all. It is believed that the high fiber and protein content in oatmeal helps to slow down digestion and promote a slower and more sustained release of glucose into the bloodstream. This controlled release of glucose positively influences the way the brain uses it, especially when it comes to memory performance.
