Relationship between Dietary Components and Aspects of Sleep

Abstract

To test the hypothesis that major dietary constituents are related to quantity or quality of sleep, 27 adult volunteers participated in a five-day study. Subjects completed detailed dietary logs each day, and each morning completed the St. Mary's Hospital Sleep Questionnaire. Dietary data were converted to seven major nutritional constituents and these were averaged over the 5-day period. None of the 98 correlations between diet and sleep were significant. These findings provide no support for a link between sleep and diet in adults.
