  • 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.

    Unraveling the mysteries of the subaleurone layer in rice

    There’s an ingredient in rice that may help control blood pressure and explain the lower risk of cardiovascular disease in Japan.

    Researchers at Temple University, in Philadelphia, Pennsylvania, presented the results of their laboratory study during the annual 2010 Experimental Biology conference.

    First, some background.

    • The subaleurone layer of Japanese rice (between the white center and brown fibrous outer layer) contains oligosaccharides (sugars) and dietary fibers, which provide nutritional benefits.
    • Polishing to make white rice removes the subaleurone layer.

    And, the results.

    • In the laboratory, some of the subaleurone components inhibited angiotensin II activity in cultured vascular smooth muscle cells.

    The bottom line?

    This finding suggests that something in the subaleurone layer of rice — possibly a statin — might protect against high blood pressure and atherosclerosis. It could also help explain why fewer people die of cardiovascular disease in Japan, where most people eat at least one rice-based dish per day, than in the US, where rice is not a primary component of daily nutrition.

    This “ingredient in rice… may be a good starting point for looking into preventive medicine for cardiovascular diseases,” concluded the authors.
