In this large scale epidemiological study of diet, lifestyle practices, and disease status among 39 765 men and 157 463 women, higher intake of white rice (> 4 servings per week vs < 1 per month) was associated with a higher risk of type 2 diabetes: pooled relative risk 1.17 (95% confidence interval 1.02 to 1.36).
The authors conclude with the recommendation that most carbohydrate intake should come from whole grains rather than refined grains to help prevent type 2 diabetes.
