Determine Food Sources of Zinc?
Zinc is normally associated with the protein and/or nucleic acid fraction of foods. Thus, foods high in proteins are good sources of zinc. Lean red meat, whole-grain cereals, pulses and legumes provide the highest concentrations of zinc: concentrations in such foods are generally in the range of 25-50 mg/kg (380-760 μmol/kg) raw weight. Processed cereals with low extraction rates, polished rice, and chicken, pork or meat with high fat content have moderate zinc content, typically between 10 and 25 mg/kg (150-380 μmol/kg). Fish, roots and tubers, green leafy' vegetables, and fruits are only modest sources of zinc, having concentrations
