  • But the highest rates of fructures are found in
    countries with high dairy consumption, and large
    prospective studies have not shown a lower risk
    of fructures among those who eat plenty of dairy
    products.

  • The Harvard Nurses Health Study, which followed
    more than 75,000 women for 12 years, showed no
    protective effect of increased milk consumption
    on fracture risk. In fact, increased intake of
    calcium from dairy products was associated with a
    higher fracture risk.

    no protective effect of dairy calcium on bone.

  • Decrease your risk of osteoporosis by reducing
    sodium and animal protein intake in the diet,
    increasing intake of fruits and vegetables,
    exercising, and ensuring adequate calcium intake
    from plant foods such as leafy green vegetables
    and beans, as well as calcium-fortified products
    such as breakfast cereals and juices.

  • The average protein intake in many
    industrialized countries is at least 50 above
    recommended levels. Excess protein intake has
    been proposed as a reason for the high incidence
    of osteoporosis in such populations despite
    moderate to-high average calcium intakes. The
    proposed mechanism is the calciuric effect of
    protein. Over a wide range of protein intake, an
    average increase in dietary protein of 1 gram
    results in the loss of an additional 1 mg of
    calcium in the urine. The effect of protein is
    rapid and is not balanced by a change in calcium
    absorption.

  • Another factor implicated in bone loss is the
    possibility that excessive acid intake,
    particularly in the form of high-protein diets,
    results in dissolution of bone in an attempt to
    buffer the extra acid.

  • Increased phosphorus has an opposing effect on
    calcium balance A diet high in phosphorus and
    low in calcium produced an increase in PTH
    secretion. If extended over a long period of
    time, it is suspected that this common dietary
    pattern could lead to unfavorable bone balance,
    but this has not been demonstrated.

  • " What is more, we cannot assume that high dairy
    consumption is safe in several studies, men who
    consumed large amounts of dairy products
    experienced an increased risk of prostate
    cancer, and in some studies, women with high
    intakes had elevated rates of ovarian cancer.

    Pyramid. Scientific American, January 2003 , pp.

  • According to a study by Daniel Cramer, M.D., and
    his colleagues at Harvard, when dairy product
    consumption exceeds the enzymes capacity to
    break down galactose, it can build up in the
    blood and may affect a womans ovaries.

    consumption and metabolism in relation to the
    risk of ovarian cancer. Lancet 1989266-71.

  • Higher intake of meat and dairy products has
    been associated with greater risk of prostate
    cancer, which may be related to their saturated
    fat content.
  • Modern Nutrition In health Disease 1999, P.
    1250. Diet, nutrition, and the prevention of
    cancer.

22
  • In a large case-control study among various
    ethnic groups within the US, consistent
    association with prostate cancer risk were seen
    for saturated fat, but not with other types of
    fat.
  • Whitteemore AS et al. J Natl Cancer Inst
    199587652-61.

23
  • Although further data are desirable, the
    evidence from international correlations,
    case-control, and cohort studies is reasonably
    consistent in supporting an association between
    consumption of fat-containing animal products and
    prostate cancer incidence.

  • IGF-I is found in cows milk and has been shown
    to occur in increased levels in the blood by
    individuals consuming dairy products on a regular
    basis.
  • A recent study showed that men who had the
    highest levels of IGF-I had more than four times
    the risk of prostate cancer compared with those
    who had the lowest levels.

    ??????.

26
Cholesterol-raising fatty acids (CRFA)
  • can be calculated as the sum of
    cholesterol-raising saturated FA plus trans FA.
    About 2/3 of Saturated FA in the american diet
    comes from animal fat. Sources of animal fat
    include milk fat and meat fat. Milk fat is more
    hypercholesterolemic than meat fat because of its
    higher content of cholesterol-raising fatty
    acids.

Most prevalent FAs in milk C14/16/180
  • A review of the literature shows palmitic acid
    (C160) to be a potent CRFA. Another SFA ,
    Myristic acid (C140), occurs in lesser amounts
    in the diet, but it appears to be even more
    potent than palmitic acid in elevating the serum
    LDL- Cholesterol concentration.
