145 Breakfast Improves Mental Sharpness If you are not in the habit of having breakfast， then you should start doing so. A recent study shows that not only is breakfast the most important meal of the day， but it is also important to eat it at the right time. The timing of breakfast may affect one’s performance in school or at work. For instance， if children eat breakfast 30 minutes before school， they will probably do better than those who eat it two hours earlier. What you eat is also an important factor. If you eat sweet foods， they will probably improve your ability to think and remember. In brief， the study claims that they improve mental sharpness. If I were you， I would give it a try. After all， what’s there to lose？
