A comparative study of the EAT-Lancet diet and the Mediterranean diet in relation to neuroimaging biomarkers and cognitive performance.

ABSTRACT:

Background

The impact of the sustainable EAT-Lancet planetary health diet on brain and cognitive health remains unclear. This study compared the impact of the EAT-Lancet diet with the well-established cognitive-beneficial Mediterranean diet (MeDi) in relation to neuroimaging biomarkers and cognitive performance among older adults.

Methods

The study included 615 dementia-free 70-year-olds from the Swedish population-based Gothenburg H70 Birth Cohort study. Dietary adherence was measured with EAT-Lancet diet and MeDi scores. Neuroimaging measures included cortical thickness, hippocampal volume, small vessel disease, and deep learning-derived brain age. Cognitive performance was assessed with a global cognitive composite score.
