High consumption of white rice (≥450 g/day) is associated with an increased risk of incident type 2 diabetes, with the strongest association observed in South Asian populations.
If you eat large amounts of white rice (more than 3 cups cooked per day), your risk of developing type 2 diabetes increases, especially if you are of South Asian descent. To reduce this risk without necessarily giving up rice, try switching to brown rice, choosing high-fiber white rice varieties, or adding legumes (beans, lentils) to your rice meals to lower the glycemic impact. Be aware that in China, this specific risk was not statistically significant, suggesting regional or varietal differences.
In the overall PURE cohort, after adjusting for lifestyle and dietary factors, higher consumption of white rice (≥450 vs. <150 g/day) was significantly associated with an increased risk of incident diabetes (HR 1.20; 95% CI 1.02–1.40; P for trend = 0.003). The subgroup analysis by regions showed that the association was most pronounced in South Asia (HR 1.61; 95% CI 1.13–2.30; P for trend = 0.02).
Why this rating
Large multinational prospective cohort (n=132,373) with long follow-up (9.5 years) and multivariable adjustment, though observational design limits causal inference.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
