man - J Am Coll Nutr. 1994 Oct;13(5):479-84 - "the overall effect of the high Zn intake of the three groups combined,

absorption and of the Mg balance"

Increasing the Good Cholesterol - Health & Nutrition Breakthrough, 1/99
- "Low copper levels, which can be
induced by taking more than 25 mg/day of zinc, may increase triglycerides as

Copper
- Vitacost Health Library - "Cupric
oxide (CuO) is a form of copper frequently used in vitamin-mineral
supplements sold over-the-counter. However, animal studies have shown
conclusively this form of copper is poorly absorbed from the gut; it should
therefore not be used in supplements"

Damages Protein That Defends Against Alzheimer's - Science Daily, 11/7/07 -
"Copper can damage a molecule that escorts out of the
brain a substance called amyloid beta that builds up in toxic quantities in the
brains of people with Alzheimer's disease ... having appropriate levels of
copper in our body is crucial for our health. Copper helps keep our bones our
strong and our skin toned, and it helps our nerves fire crisply and our cells to
generate the energy we need to live. It helps keep our blood healthy so we can
get the oxygen we need to all our organs. And it plays a role in keeping our
immune system strong"

Dietary
Copper May Ease Heart Disease - Science Daily, 3/5/07 -
"Insufficient copper intake is
associated with increases in cholesterol levels, clot formation, and heart
disease. The new study found that feeding mice copper relieved heart disease and
restored proper heart function, even when the animals' hearts were continually
stressed ... The human equivalent of the beneficial dose of copper used in this
study is about 3.0 mg/day. The current recommended daily intake for humans,
however, is only 0.9 mg/day"

Intake Of Dietary Copper Helps Alzheimer's Patients - Science Daily,
10/4/05 - "low copper level in blood
correlates with advanced memory deficits ... Patients with higher blood
copper levels make fewer mistakes in this memory test. This result supports
the notion of a mild copper deficiency in AD patients. An increased uptake
of dietary copper may therefore be therapeutically relevant"
-
Copper levels in supplements should be reduced - Nutra USA, 7/5/05 -
"routine use of dietary copper
supplements containing 2 mg or more per day could lead to accumulation of
excess copper"

Low Dietary Copper Increases Fecal Free Radical Production,
Fecal Water Alkaline Phosphatase Activity and Cytotoxicity in Healthy Men
- J. Nutr. 133:522-527, 2/03 - "One possible
dietary factor that may increase susceptibility to
colon cancer is inadequate copper intake ... Low dietary copper
significantly (P < 0.01) increased fecal free radical production"

Inadequate Copper Intake Reduces Serum Insulin-Like Growth
Factor-I and Bone Strength in Growing Rats Fed Graded Amounts of Copper and
Zinc - J. Nutr. 133:442-448, 2/03 - "In summary, growing rats fed low and marginal Cu had lower serum
IGF-I than those fed high dietary Cu. Bone strength was also reduced
with low dietary Cu, despite compensatory changes in the bone matrix"
- So maybe a copper deficiency is a reason that many aren't getting an IGF-1
rise from growth hormone. A copper deficiency can be caused by taking
too much zinc.
