Rice

White rice has displaced many traditional whole grains across Asia, so researchers wonder how white rice might relate to diabetes risk. In a study of 45,411 Chinese adults followed for 11 years, researchers found that replacing white rice with white bread and whole grain bread can reduce type 2 diabetes risk by 10% and 18% respectively, and that replacing white rice with noodles, red meat, or poultry might actually increase diabetes risk. Rice intake itself was not associated with higher type 2 diabetes. The authors conclude that “recommendations to reduce high white rice consumption in Asian populations for the prevention of [type 2 diabetes] may only be effective if substitute foods are considered carefully.”

Many people are surprised at how effective lifestyle changes can be when it comes to managing chronic disease. In this study, 160 hospital patients in South Korea with high blood pressure changed their diet to eat a plant-based (vegan) diet based on brown rice at each meal, with lots of kimchi and pickled vegetables, fermented soy foods, and lots of other vegetables (both raw and cooked). They averaged about 1,700 calories per day and did not eat any refined grains or any noodles or breads, relying on brown rice as the staple. Their sodium intake was quite high, at 7,382mg per day. However, after about 2 weeks, 86% of the patients were able to stop taking their blood pressure and diabetes medications, and their reduced blood pressure levels remained stable even after stopping the medications. Similarly, HBA1C reduced from 7.6 to 7.2, indicating better blood sugar management. More research is needed to see if similar approaches might be effective in other populations.
