Aspartame and Human Behavior: Cognitive and Behavioral Observations
- 107 Downloads
Little is known regarding the possible cognitive and behavioral effects of the artificial sweetener aspartame in humans. Few, if any, studies have addressed the issues raised by the potential elevation of brain phenylalanine levels which may be induced by aspartame ingestion and the concomitant depletion in specific neurotransmitter supplies which may result. In this chapter, the relevant literature addressing this topic is reviewed, the results of a new double-blind, acute study are briefly summarized, and findings from the pilot phase of a new chronic exposure study are reviewed.
