When you first take a bite of sugary cereal, your taste receptors that respond to sweetness, found at the tip of your tongue, send a signal to the portion of your brain called the cerebral cortex.
This signal activates ‘the reward system’ and causes you to want to take another bite. Excessive activation of this reward system, Dr. Avena suggests, can cause ‘loss of control, craving and intolerance to sugar.’
