Abstract

BACKGROUND: Because of differences in processing and nutrients, brown rice and white rice may have different effects on risk of type 2 diabetes mellitus. We examined white and brown rice consumption in relation to type 2 diabetes risk prospectively in the Health Professionals Follow-up Study and the Nurses' Health Study I and II. METHODS: We prospectively ascertained and updated diet, lifestyle practices, and disease status among 39,765 men and 157,463 women in these cohorts. RESULTS: After multivariate adjustment for age and other lifestyle and dietary risk factors, higher intake of white rice (> or =5 servings per week vs <1 per month) was associated with a higher risk of type 2 diabetes: pooled relative risk (95% confidence interval [CI]), 1.17 (1.02-1.36). In contrast, high brown rice intake (> or =2 servings per week vs <1 per month) was associated with a lower risk of type 2 diabetes: pooled relative risk, 0.89 (95% CI, 0.81-0.97). We estimated that replacing 50 g/d (cooked,equivalent to one-third serving per day) intake of white rice with the same amount of brown rice was associated with a 16% (95% CI, 9%-21%) lower risk of type 2 diabetes,whereas the same replacement with whole grains as a group was associated with a 36% (30%-42%) lower diabetes risk [corrected]. CONCLUSIONS: Substitution of whole grains, including brown rice, for white rice may lower risk of type 2 diabetes. These data support the recommendation that most carbohydrate intake should come from whole grains rather than refined grains to help prevent type 2 diabetes.

  • Replacing white with brown rice (50 grams/day) reduced T2DM risk by 16%.

    “Replacing white with brown rice (50 grams/day) reduced T2DM risk by 16% (113),”
  • In the Nurses' Health Study, higher consumption of white rice is associated with increased risk of diabetes, whereas consumption of brown rice protects against the disease.

    “Despite relatively low consumption of rice in the U.S. population, in the NHS, we found that higher consumption of white rice is associated with increased risk of diabetes, whereas consumption of brown rice, a whole grain, protects against the disease (23).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
