Ultra-processed food intake and cognitive decline in older adults.
Article in European journal of nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundGlobal ultra-processed foods (UPFs) intake has increased. While several studies have linked the intake of specific UPF products to cognitive decline, fewer have investigated overall dietary UPF intake, with conflicting results.
objectiveTo examine the association of overall UPF intake with cognitive function and 10-y decline among Dutch older adults (≥ 55 years).
methodsData from 1371 participants of the Longitudinal Aging Study Amsterdam (LASA) were used. Cognitive function was assessed four times between 2011/2012 and 2021/2022 using five tests covering global cognition (MMSE), information processing speed (Coding task), episodic memory (15-Word Test) and executive function (Word Fluency and Digit span). Dietary intake was measured in 2014/2015 with a validated food frequency questionnaire. Food items were classified as UPFs based on the NOVA classification. Total UPF intake was expressed as a percentage of total dietary intake in grams, and divided into quartiles (1.5– < 13.2%, 13.2– < 18.5%, 18.5– < 24.9% and 24.9–72.4%). Linear mixed models assessed associations between UPF intake quartiles and cognitive function and decline with age, while adjusting for potential confounders and testing for interaction with sex.
resultsOn average, UPFs contributed 20.1% of total dietary intake in grams per day. No associations were found between UPF intake and cognitive function or decline with age for any of the cognitive domains.
conclusionWe found no evidence of an association between total UPF intake and cognitive function or decline with age in Dutch older adults.
