BACKGROUND: The EAT Lancet diet is increasingly recognized for its simultaneous benefits to human and planetary health. Its key components are known to exert anti-inflammatory and antiplatelet effects; however, the potential association between adherence to the EAT‑Lancet diet and incident venous thromboembolism (VTE), as well as the underlying biological mechanisms, remains unclear. METHODS: This prospective study involved 201,695 UK Biobank participants who were free of VTE at baseline, and integrated large-scale Olink plasma proteomics to identify diet-related molecular signatures. Adherence to the EAT-Lancet diet was quantified using two validated indices. Cox models were employed to evaluate associations between EAT-Lancet diet, plasma proteins, and incident VTE (including deep vein thrombosis DVT and pulmonary embolism PE). Mediation analyses quantified the role of plasma proteins. RESULTS: During a median follow-up of 13.77 years, participants in the highest adherence group of the Stubbendorff index showed lower risks of VTE (HR = 0.809, 95% CI: 0.750-0.874), DVT (HR = 0.856, 95% CI: 0.781-0.938), and PE (HR = 0.754, 95% CI: 0.678-0.838). Consistent protective associations were observed with the Knuppel index. Mediation analyses identified 94 shared plasma protein mediators, with mediation proportions ranging from - 4.77% to 8.45% of the association, among which FABP4, LEP, and ENPP6 were the top-ranked mediators. The overall proteomic signature mediated 59.19% (95% CI: 27.02%-92.15%) and 40.10% (95% CI: 14.53%-65.96%) of the associations between the Stubbendorff and Knuppel index and incident VTE, respectively. CONCLUSIONS: Higher adherence to the EAT-Lancet diet is significantly associated with a reduced risk of incident VTE, DVT, and PE, with plasma proteins potentially mediating this effect.
