Human brain is a great machine that needs 25% of oxygen, sugar and calories consumed by the body; it became clear that the process of thinking require most of them (1). Your brain cells need two times more energy than the other cells in your body. Neurons, the cells that communicate with each other, have a high demand for energy because they're always in a state of metabolic activity. Even during sleep, neurons are still at work repairing and rebuilding their own out structural components (2). As known, energy comes from glucose sugar thus from food.
