Distribution of selected minerals in some Nigerian white breads

Abstract

The minerals content of white breads consumed in 15 states and Federal Capital Territory of Nigeria were determined using atomic absorption spectrophotometry. The levels of Ca (528-1250mg 100g^-1), Na (240–920mg 100g^-1), Mg (120–460mg 100g^-1) and K (70–1060mg 100g^-1) were high. The levels of Cd (ND–0.52mg Kg^-1) and Pd (0.72–1.82mg Kg^-1) were low and below WHO maximum standard. The bread samples were found to be very good sources of the minerals examined, except the toxic minerals (Cd and Pd) which must be regularly monitored in order to minimize their intake.
