Summary
This prospective cohort study in EPIC-Potsdam identified specific ceramide and dihydroceramide species that independently predict type 2 diabetes and cardiovascular disease risk, using a novel network-based approach. Mendelian randomisation supported a causal role for ceramide C22:0 in type 2 diabetes aetiology, and mediation analyses suggested these lipid metabolites link dietary habits (red meat consumption, coffee intake) and genetic predisposition to cardiometabolic disease risk.
Regional applicability
The study was conducted in Germany and may have limited direct applicability to UK populations, which differ in dietary patterns, genetic ancestry, and lifestyle factors. However, the mechanistic findings regarding ceramide biology and cardiometabolic disease pathways are likely relevant to understanding disease aetiology in UK populations, though UK-specific validation would be warranted.
Key measures
Plasma ceramide (C16:0, C18:0, C20:0, C22:0) and dihydroceramide (C20:0, C22:2, C26:1) concentrations; incidence of type 2 diabetes and cardiovascular disease; mediation analysis of dietary associations
Outcomes reported
The study identified specific ceramide and dihydroceramide species associated with prospective risk of type 2 diabetes and cardiovascular disease in a nested case-cohort design. It also examined whether these lipid metabolites mediate associations between dietary factors (red meat, coffee) and cardiometabolic disease risk.
