Also studies then did not consistently support a hypothesis relating sweet preference to serotonin activity within the brain.
Results then provided preliminary evidence that craving for sweet food may be a significant part of the clinical syndrome of dementia. But at that time further research was needed to delineate the psychological and biological mechanisms accounting for it. Now a new study shows that insulin acts differently in the brain than elsewhere. Continue to read: examiner.com
