Stage-specific nutritional blueprints of date fruit revealed by integrated LC-MS metabolomics and ICP-OES profiling.
Article in NPJ science of food, 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 biochemical changes during date fruit (Phoenix dactylifera L.) maturation were studied using untargeted LC-MS metabolomics and ICP-OES mineral profiling across four ripening stages (Hababouk, Kimri, Rutab, and Tamr). Metabolite analysis showed stage-specific shifts in organic acids, flavonoids, lipids, and sugars, with early stages rich in antioxidants (malic acid, ferulic acid, diosmin) and minerals. Later stages accumulated simple sugars, prebiotic oligosaccharides (stachyose), and cardioprotective polyphenols (apigenin glycosides, procyanidin B2, niacin). Mineral content gradually decreased from Hababouk to Tamr, except for sodium, which peaked during Rutab, likely due to dehydration-related ionic adjustments. Ripening stages exhibited enriched carbohydrate and amino acid metabolism pathways, with key metabolites associated with neurological, metabolic, and cancer disorders. These results create a compositional profile linking fruit development to nutritional benefits: mineral- and antioxidant-rich extracts from early stages, neuroprotective compounds from Rutab, and energy-rich prebiotic foods from Tamr. Combining metabolomic and mineral data offers valuable insights for optimizing harvest timing, designing functional foods, and developing nutraceuticals.
