Food chemicals steer sleep and alertness via brain serotonin
University of Toronto researchers Dr. Harvey Anderson and Dr. Carol Greenwood show meals high in carbohydrates raise brain serotonin and promote sleepiness, while high protein meals increase amino acids reaching the brain, boosting alertness. They link insulin shifts to tryptophan delivery and note gender differences in appetite responses. Studied under NSERC and MRC funding.
