White rice consumption and risk of type 2 diabetes: meta-analysis and systematic review

To summarise evidence on the association between white rice consumption and risk of type 2 diabetes and to quantify the potential dose-response relation.

Meta-analysis of prospective cohort studies. DATA SOURCES: Searches of Medline and Embase databases for articles published up to January 2012 using keywords that included both rice intake and diabetes; further searches of references of included original studies. STUDY SELECTION: Included studies were prospective cohort studies that reported risk estimates for type 2 diabetes by rice intake levels. DATA SYNTHESIS: Relative risks were pooled using a random effects model; dose-response relations were evaluated using data from all rice intake categories in each study.
