Dietary Intervention With Lutein, Docosahexaenoic Acid, and Choline During Early Development Improves Recognition Memory in Young Adult Females in an Experimental Model.
Article in Molecular nutrition & food research, 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
The perinatal period and adolescence are critical for brain development, with nutrition being a crucial factor. Dietary intake of lutein, docosahexaenoic acid (DHA), and choline is positively associated with early neurodevelopment and cognitive function, but interactions remain unclear. This study systematically evaluates lutein, DHA, and choline to elucidate their specific and combined effects on neurodevelopment. To ensure fully controllable conditions, we performed nutritional interventions on a rat model during a critical developmental phase (days 14-56 after birth). After completion of the intervention, no relevant alterations in the open field test or the elevated zero maze were detected. However, both the combination of lutein, DHA, and choline and lutein monotherapy led to an increase in the recognition index for new objects in female rats. No relevant effects on blood and metabolic parameters were observed in any group. In vivo MRI analyses ruled out differences in brain morphology. Our results provide evidence that lutein supplementation during brain development has positive effects on recognition memory in female rats, underscoring the need for sex-specific research on nutritional strategies. Lutein supplementation, particularly in combination with DHA and choline, to enhance neurological development potential should be investigated in further translational studies.
