  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    White rice, brown rice, and the risk of type 2 diabetes

    Because of differences in processing and nutrients, brown rice and white rice may have different effects on risk of type 2 diabetes mellitus.

    Researchers at Harvard Medical School, in Boston, examined white and brown rice consumption in relation to what is sometimes referred to as non-insulin-dependent diabetes (NIDDM) risk.

    First, the details.

    • 39,765 men and 157,463 women in the Health Professionals Follow-up Study and the Nurses’ Health Study I and II were interviewed to determine diet, lifestyle practices, and disease status.

    And, the results.

    • After adjusting for age and other lifestyle and dietary risk factors, higher intake of white rice (at least 5 servings/week vs less than 1/month) was associated with a higher risk of type 2 diabetes.
    • In contrast, high brown rice intake (at least 2 servings/week vs less than 1/month) was associated with a lower risk of type 2 diabetes.
    • It was estimated that replacing 50 grams/day (uncooked, equivalent to one-third serving per day) intake of white rice with the same amount of brown rice was associated with a 16% lower risk of type 2 diabetes.
      • The same replacement with whole grains as a group was associated with a 36% lower diabetes risk.

    The bottom line?

    The authors concluded, “These data support the recommendation that most carbohydrate intake should come from whole grains rather than refined grains to help prevent type 2 diabetes.”

    Whole grains or foods made from them contain all the essential parts and naturally-occurring nutrients of the entire grain seed. A list of these grains is here.

    Milling and polishing brown rice produce white rice. This process removes the fiber and most of the minerals and nutrients in the grain, which leads to more rapid digestion and uptake of sugar into the blood.
