Cells of the nervous system, including the brain, rely less on blood sugar (glucose) for energy than do other body cells.

The above statement is false.

Cells of the nervous system, including the brain, rely more on blood sugar for energy than do other body cells. Cells of the brain and the nervous system are energy-hungry. Brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the food consumed daily and is regularly delivered to brain cells through the blood.
