Bioavailability of zinc from different pakistani cereal grains

ABSTRACT

The zinc has been determined by Neutron Activation Analysis while phytate by spectrophotometric method in some Pakistani cereal grains. The zinc phytate ratio found is more than 401 in all cereal grains which is far more than the suggested binding ratio of 41. Therefore, bioavaliability of zinc from Pakistani cereal grains is more than sufficient and no deficiency can be encountered due to bioavailability of zinc. The only deficiency of zinc which could happen will be due to the pathological conditions
