    Manganese is a trace mineral that is essential for many important functions in the body. It acts as a cofactor for many enzymes involved in metabolism. Manganese is necessary for bone development, wound healing, blood sugar control, and protecting against free radical damage. Good food sources of manganese include whole grains, nuts, leafy vegetables, and teas. While deficiencies are rare, prolonged deficiency can impact growth, digestion, bone development and fertility. Toxicity from high levels is also rare when consumed through diet alone.

    MANGANESE

    PALASI, JUDELITA
    PIAS, EZRA KATE JOY
    DESCRIPTION

     Inthe 1930s, researchers


    discovered that our bodies
    require small amounts of
    dietary manganese each
    day. Since then, it has been
    determined that each adult
    has about 15-20 mg of
    manganese stored in his or
    her body.
     Manganese is a cofactor for
    enzymes involved in hydrolysis,
    phosphorylation,
    decarboxylation, and
    transamination.
     Manganese is an important
    component of many enzyme
    systems which are involved in the
    metabolism of carbohydrates,
    fats, and proteins.
    FUNCTIONS: HEALTH
    Bone development.

     Manganese is the preferred


    cofactor of enzymes called
    glycosyltransferases which
    is required for the synthesis
    of proteoglycans that are
    needed for the formation
    of healthy cartilage and
    bone.
     Osteoporosis: Manganese and
    other trace elements are
    necessary for bone health.
    Therefore, many experts feel
    that appropriate balance and
    intake of manganese and
    these other nutrients may play
    a role in preserving bone
    density and preventing
    osteoporosis.
    Wound healing

     Wound healing is a
    complex process that
    requires increased
    production of collagen.
    Blood Sugar Control

     Manganese is needed to
    help multiple enzymes in a
    process called
    gluconeogenesis.
    Protection Against
    Free Radical Damage
     As noted above, manganese
    is a co-factor for an enzyme
    called manganese
    superoxide dismutase
    (MnSOD), which is a potent
    antioxidant associated with
    protection against free
    radical damage.
    Health Benefits of
    Manganese
     Also includes:
    1.Free Radicals
    2.Inflammation and sprains
    3.Preventing Osteoporosis
    4.Alleviating PMS syndrome
    5.Thyroid health
    SOURCES
     FOOD SOURCES. Rich sources of
    manganese include whole
    grains, nuts, leafy vegetables,
    and teas. Foods high in phytic
    acid, such as beans, seeds, nuts,
    whole grains, and soy products,
    or foods high in oxalic acid, such
    as cabbage, spinach, and
    sweet potatoes, may slightly
    inhibit manganese absorption.
    Although teas are rich sources of
    manganese,
    the tannins present in tea may
    moderately
    reduce the absorption of
    manganese

    RISK FOR DEFICIENCY
     Non-vegetarian diets= insufficient
    intake of manganese
     Unusual medical problems
    Effects of deficiency
     A prolonged deficiency of manganese
    may cause retarded growth, digestive
    disorders, abnormal bone development,
    and deformities. It may also cause male
    and female sterility and sexual
    impotence in men. However, the human
    body obtains sufficient manganese
    through normal dietary intake, so a
    deficiency syndrome is rare.
    EFFECTS OF EXCESS:
     No reported cases of manganese
    toxicity resulting from dietary intake
    have been reported. Manganese
    toxicity has been observed from
    inhalation manganese-containing
    dust by workers in mines and steel
    mills manifested by adverse effects
    on the central nervous system. The
    upper limit of safety for manganese
    established by the Food and Nutrition
    Board of the Institute of Medicine is
    approximately 11 mg daily for adults.
     Symptoms of manganese
    toxicity include headaches,
    tremors, loss of appetite,
    muscle rigidity, leg cramps
    and hallucinations. Some
    people with manganese
    toxicity may get extremely
    irritable and be prone to acts
    of violence
    METABOLISM:
     Only three to four percent of the
    manganese present in the diet is
    absorbed from the intestine and
    reaches the blood. It is stored in the
    blood and liver. Serum manganese
    levels are almost always elevated
    following a myocardial infarction.
    Manganese is excreted in the feces.
    The urine contains only traces of this
    element. High calcium intakes have
    been shown to increase the fecal
    excretion of manganese.
