  1. Fulltext. Whole-grain intake may reduce the risk of ischemic heart disease death in postmenopausal women : the Iowa Women's Health Study.

    Article - En anglais



    A recent review of epidemiologic literature found consistently reduced cancer and heart disease rates in persons with high compared with low whole-grain intakes.


    We hypothesized that whole-grain intake was associated with a reduced risk of ischemic heart disease (IHD) death.


    We studied 34492 postmenopausal women aged 55-69 y and free of IHD at baseline in 1986.

    There were 438 IHD deaths between baseline and 1995.

    Usual dietary intake was determined with use of a 127-item food-frequency questionnaire.


    Whole-grain intake in median servings/d was 0.2,0.9,1.2,1.9, and 3.2 for quintiles of intake.

    The unadjusted rate of IHD death was 2.0/1 x 103 person-years in quintile I and was 1.7,1.2,1.0, and 1.4 IHD deaths/1 x 103 person-years in succeeding quintiles (P for trend<0.001).

    Adjusted for demographic, physiologic. behavioral, and dietary variables, relative hazards were 1.0. 0.96. 0.71,0.64, and 0.70 in ascending quintiles (P for trend=0.02).

    The lower risk with higher whole-grain intake was not explained by intake of fiber or several other constituents of whole grains.


    A clear inverse association between whole-grain intake and risk of IHD death existed.

    A causal association is plausible because whole-grain foods contain many phytochemicals, including fiber and antioxidants, that may reduce chronic disease risk.

    Whole-grain intake should be studied further for its potential to prevent IHD and cancer.
