This controlled study was designed to test the popular idea that ostensibly lowered blood sugar following excessive sugar intake adversely affects mood. Fifty-three normal subjects divided into three groups received respectively a sucrose solution, a saccharin solution, or water. Results from a self-reported mood scale, the serial sevens test for cognitive efficiency, and a self-report neuroticism scale, all administered before the solutions were taken and 20 minutes and four hours later, did not indicate that sugar ingestion noticeably affects mood more than ingestion of saccharin or water.
