Consumption of a diet high in fat and sugar is associated with worse spatial navigation ability in a virtual environment

The results highlight the impact of diet beyond traditional indicators of physical health, and reveal the specificity of the association between diet and spatial ability. These findings are consistent with those from animal studies and are the first to reveal the adverse effect of diet on spatial learning and memory in a task that requires navigation in three-dimensional space. The results confirm the importance of making healthy dietary choices for cognitive health.
