zinc

talk to me.

A metallic chemical element, chemical symbol Zn, atomic number 30. Zinc is a bluish silver metal, ductile when very pure but brittle otherwise. It forms brass (with copper) and many other alloys. Its major use is in galvanizing iron, steel, and other metals. Zinc is an essential trace element, particularly in red blood cells; in snails, it corresponds to iron in the blood of vertebrates. Zinc oxide is used as a pigment, ultraviolet light absorber (to prevent sunburn), dietary supplement and seed treatment, and photoconductor. Zinc's many other compounds (in which it has valence 2 or, rarely, 1) are used in industrial and consumer applications, incl. as pesticides, pigments, mordants (see dye), fluxes, and wood preservatives.

Maybe you could be a little more specific with your question.

I don't really believe in supplements.
However i'm interested in Zinc and Selenium.
Men lose big amounts of Zinc in Sperm and Selenium is uncommon in our food.

I'm concerned though, because they seem to stimulate prostate cancer.
Anybody have any ideas/concerns?

Concerns yes, enough for me to stop taking zinc.  If you are going to consume, however, I would recommend combining with a lycopene supplement (evening out the odds, perhaps?)

      Zinc has the potential to be toxic if too much is taken. Excess zinc can result in copper deficiency, which is associated with anemia as well as a factor to prostate cancer. Yet, many people are zinc deficient
    You can get a test marker for prostate cancer known as prostate-specific antigen (PSA).  PSA is a substance normally produced by the prostate gland that can serve as an indication of prostate cancer when it rises above the level of 4 nanograms per milliliter (ng/mL) of blood.
    The average PSA level was 0.6 ng/mL for men in their 40s and 0.7 ng/mL for men in their 50s.To help you could:
   *  Vegetable juicing
    * Ground Flax Seeds
    * Vitamin D
    * Avoiding Milk
    * Natural Progesterone
     * Use broccoli or cauliflower sprouts

Do you know the exact reason why it causes copper deficiency?
From what i've read copper and zinc seem to block each other's absorption. I don't know if that's just in the digestive system.

Also one more thing worth mentioning about zinc is that it's best absorbed on an empty stomach. Def. no dairy cause calcium blocks it as well.

It could be specifically interested for bodybuilders

Zinc also is essential for protein synthesis, integrity of cell membranes, maintenance of DNA and RNA, tissue growth and repair...

They cancel each other out:
Zinc absorption is increased by Amino Acids
Absorption is decreased by:
   * Calcium
    * Iron
    * Manganese
    * Selenium
    * Copper
That is why I don't favor Multi-Vitamins so much.
