    Abstract Objectives To assess the dietary intakes and diet
    quality of menopausal women relative to premenopausal women,
    and to determine whether their diets are compatible with
    reducing risks of cardiovascular disease (CVD) and
    osteoporosis. Design Cross-sectional study using 3-day food
    records and anthropometric measurements. Subjects Thirty
    apparently healthy, nonoestrogen using and nonsupplemented
    women menopausal since 3-5 years and 30 well-matched
    premenopausal women. Outcome measures Nutrient intakes, diet
    nutrient density, body mass index (BMI), waist
    circumference, waist-to-hip ratio and serum oestradiol.
    Results Energy intake and body weight of pre- and
    postmenopausal women were comparable. Their BMI, waist
    circumference and waist-to-hip ratios were within healthy
    ranges. The diet of postmenopausal women was compatible
    (less total lipids and saturated fatty acids; more fibres,
    antioxidant vitamins and potassium) with North American
    nutritional recommendations linked to cardiovascular health.
    Their dietary iron intakes exceeded their reduced
    physiological need, which may jeopardize their
    cardiovascular system. Their calcium and vitamin D intakes
    were far below recommendations for healthy bones. Five other
    nutrients were also suboptimal. Phosphorus intake (high in
    both groups) correlated with dietary proteins, sulphur amino
    acids and calcium. Conclusions The diet of the
    postmenopausal women studied were more compatible with
    national nutritional recommendations than that of
    premenopausal controls. However, these postmenopausal women,
    not taking hormone replacement therapy (HRT) and having
    inadequate dietary calcium and vitamin D intakes, may be at
    increased risk of osteoporotic fracture later in life. More
    studies on CVD risk inherent to body iron accumulation
    involving a large number of postmenopausal women are
    warranted before planning public health measures regarding
    dietary iron intake.
