Online ahead of print.ABSTRACTThis structured narrative review is a study of foods specifically mentioned in the Quran and for which recent scientific findings support several nutritional observations mentioned in the hadith literature. The two-phase method was used: searching for scripturally described foods and summarizing the literature (2016-26) available in PubMed, Scopus, and Web of Science. It was found that 16 foods were plant-, animal-, or marine-based. Compositional analysis revealed common bioactive components, including polyphenols, flavonoids, unsaturated fatty acids, soluble fiber (such as 0-glucan), thymoquinone, gingerols, and long-chain omega-3 fatty acids. Mechanistic proof suggests common antioxidant, anti-inflammatory, glycemic-regulatory, lipid-modulating, and microbiota-associated routes. The strength of clinical substantiation of the clinical benefits of olive oil, fish, and barley represents a continuum of evidence: there is comparatively strong evidence of cardiometabolic benefit in these three items, but weak to mottled evidence of promise in pomegranate, grapes, Nigella sativa, ginger, vinegar, and dates. All in all, most of the scripturally discussed foods are consistent with modern functional food paradigms; nevertheless, their health implications can be most appropriately viewed through the lens of balanced diets rather than singular therapeutic assertions. More, longer, and standardized clinical trials are required to shed light on dose-response relations and long-term disease outcomes.PMID:42364260 | DOI:10.1016/j.nut.2026.113326
