A comparative study of the EAT-Lancet diet and the Mediterranean diet in relation to neuroimaging biomarkers and cognitive performance.
Article in Alzheimer's & dementia : the journal of the Alzheimer's Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe 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.
methodsThe 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.
resultsIn multi-adjusted models, higher adherence to the EAT-Lancet diet was associated with higher total mean cortical thickness, and thicker cortex in Alzheimer's disease-signature regions, while a higher adherence to the MeDi was associated with better cognitive performance. DISCUSSION: The results indicate the beneficial effects of both the EAT-Lancet and the MeDi on brain health. HIGHLIGHTS: There were no indications of detrimental effects of adhering to the EAT-Lancet diet. Adhering to the EAT-Lancet planetary health diet was associated with thicker cortex. Results confirm links between the Mediterranean diet and better cognitive function.
