Replacing White Rice with Whole Grain Bread May Lower Diabetes Risk

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.”

Switch to Whole Wheat for Better Liver Health

The liver is important for metabolism, so researchers wonder how substituting whole grains might impact liver health. To assess this relationship, 50 overweight middle-aged adults were randomly assigned to a diet with 5 servings of whole wheat foods per day or 5 servings of refined wheat foods per day for 12 weeks, and compliance was confirmed by measuring biomarkers of whole wheat intake (alkylresorcinol). The refined wheat diet significantly increased liver fat, indicating that it may contribute to the development of nonalcoholic fatty liver disease. On the other hand, the whole wheat diet prevented an increase in liver fat, and better maintained liver health.

Whole Grains Associated with Lower Risk of Diabetes

Whole grains are healthy carbohydrate foods that may be especially protective against type 2 diabetes. In this study, researchers analyzed the eating habits and health status of 55,465 middle-aged adults in Denmark. Those eating more whole grains were 11% and 7% less likely to develop type 2 diabetes (for men and women, respectively) over the 15-year study period. Rye bread, whole-grain bread, oatmeal, and muesli were all significantly associated with a lower risk of type 2 diabetes for both men and women, indicating a benefit for whole grains in general, rather than just one specific type of whole grain food.
