Abstract

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

Design 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. Read More
