Background & Aims: Some foods rich in cholesterol are associated with high risk of type 2 diabetes (T2D). To confirm the association between dietary cholesterol intake and T2D risk, we performed a meta-analysis of observational studies.
Methods: We searched for longitudinal studies that provided data on the relative risk (RR) for T2D in relation to the cholesterol intake level using MEDLINE (from 1950 for July 10, 2013) and EMBASE (from 1974 to July 10, 2013).
