Abstract
Cognitive function may be affected by long-term diet and most of the support for this idea is derived from human correlational studies and animal prescribed diet
studies. To date there has been no systematic examination of human
experimental studies that examine whether a prescribed long-term (24 h+)
diet can cause changes in
cognitive function. Here, we review the experimental evidence of
long-term changes in cognition following prescribed diet interventions. A total of 30 diet
interventions were identified and reviewed. Measures of working memory,
long-term memory, and attention appeared most sensitive to dietary
manipulation, but there was considerable variability in outcome.
Additionally, energy and fat intake manipulations tended to influence
performance on these measures to the greatest degree. This review also
serves to identify factors that should be considered in designing future
diet-cognition studies. We
also suggest a series of cognitive tests based on this review and
indicate potentially profitable directions to take the diet-cognition literature. © 2015 Elsevier Ltd.
