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 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 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
