Perspective: use of beef in a dietary intervention as an effective strategy for improving cognition in young adult females.
Article 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
Iron deficiency disproportionately affects young adult females and may impair cognitive performance. While supplementation has been studied, dietary interventions using iron-rich whole foods, particularly beef, remain underexplored. Beef provides highly bioavailable heme iron along with vitamin B12, zinc, choline, and creatine, nutrients implicated in neurotransmission, myelination, and cortical function. This review synthesizes evidence on beef consumption, iron status, and cognition that demonstrate improvements in attention, memory, and visuospatial processing in young adult females. We examine intervention doses, methodological differences, and limitations in current iron deficiency diagnostic thresholds. Despite mixed findings across studies, beef emerges as a feasible dietary strategy to support cognitive function in young adult females. Standardized cognitive assessments, longer interventions, and comparative analyses of alternative protein sources are needed to clarify the long-term cognitive benefits of beef. Considerations regarding red meat intake, sustainability, and evolving dietary patterns remain important. This review provides an evaluation of dietary iron from beef as a modifiable factor in cognitive performance. It also offers guidance for future research and raises concerns for balancing nutritional adequacy, health, and environmental considerations.
