Anti-inflammatory dietary patterns and cognitive aging in older adults: a scoping review of mechanistic, clinical, and nursing implications.
Synthesis in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Dietary patterns with lower inflammatory potential may support cognitive aging, but Mediterranean, Dietary Approaches to Stop Hypertension (DASH), Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND), and dietary inflammatory scores represent non-equivalent exposures, and observational findings have not been consistently confirmed in randomized trials. This scoping review mapped evidence linking whole-diet patterns and dietary inflammatory indices with cognitive aging, measured biological pathways, and clinical interpretation and potential nursing implications. Methods: PubMed, Embase, Web of Science Core Collection, and Scopus were searched from inception to 30 June 2026. Eligible studies evaluated dietary patterns or validated inflammatory indices in older adults or cohorts assessed in later life and reported cognitive, dementia, mechanistic, neuroimaging, neuropathological, or implementation outcomes. Evidence was synthesized narratively, with observational and interventional findings considered separately. Results: Thirty-eight reports were included: 27 longitudinal observational studies, seven randomized intervention reports, three cross-sectional biomarker or neuroimaging studies, and one Conclusion: The evidence is epidemiologically suggestive and biologically plausible, but does not establish that any specific diet prevents dementia. Dietary improvement may be incorporated into individualized multidomain risk reduction, provided that nutritional adequacy, frailty, cultural fit, affordability, and sustained adherence are addressed. Better-contrasted trials, temporally ordered mechanistic studies, and prospective implementation evaluations are needed.
