Trace Elements

Essential trace elements are;
—Iron
—Zinc
—Copper
Ulratrace elements:
—Cobalt
—Crom
—Fluoride
—Iodide
—Mangan
—Molibdenium
—Selenium

Iron:
—Body content 4-6 g
  in Hb %68,
ferritin 13 %,
Haemosiderin 12 %,
myoblobin 3%, 
iron enzymes 0.2 %
Sources: Leafy greens, broccoli,  whole grains, beans, pulses, liver, spleen, egg

—When iron deficient, hemoglobin cannot be produced.When there is unsufficient hemoglobin, red blood cells are small, microcyctic and hypochromic and so unable to deliver suffiennt oxygen to the tissues. This stuation is known as iron deficiency anemia

Zinc:

—Zinc is essential in the diet for growth  and development
—It is most abundant intracellular trace element
—It is involved in thr functioning of over 300 different enzymes, SOD (superoxide dismutase, protecting cells from free radical damage)
—Zinc can be bound phytates, affecting bioavailability
—It can be toxic if taken in excess as iron


Copper:

—Copper is important for enzyme activity
—Helping to prevent certain types of anemia
—The richest dietary source of copper is organ meat, seafood, nuts, whole grain foods, chocolate
—RDA 900 micrograms per day
—Zinc can decrease bioavailability of copper
