Eating During Exercise Makes You More Alert

A study from the Environmental Medical Research Institute of the United States Army in Natick, Massachusetts shows that taking extra carbohydrates during prolonged exercise markedly improves a person's ability to think and reason.

Almost all of the energy for your brain comes from sugar in your bloodstream. Most people know that exercise markedly increases your muscles' use of blood sugar, but this study shows that during exercise, the brain also has marked increase in its use of blood sugar, and that taking extra carbohydrates during prolonged exercise helps the brain to function better. So the next time you go for a long hike, run for more than an hour, cycle for more than two hours or do any continuous strenuous exercise, take in lots of fluids and calories in sugared drinks and solid foods such as nuts, seeds, beans, dried fruit, or anything else that you like to eat.

Carbohydrate administration during a day of sustained aerobic activity improves vigilance, as assessed by a novel ambulatory monitoring device, and mood.
