Bioavailability studies on zinc and copper from three different rural Nigerian peasant diets in Wistar albino rats were carried out. Serum levels of minerals were used to assess bioavailablity. The mineral composition of diets studied ranged between 0.94 and 1.79mg/100g for zinc and between 2.19 and 1.62mg/100g for copper. The serum zinc levels ranged between 1.90 and 3.54mg/l for the test groups and 3.67 and 5.54mg/l for the control groups. On the analysis of the effect of the diets on zinc bioavailability there was no significant difference (p>0.05) between group 2 fed on “foofoo and edikang ikong” which had the lowest level and group 3 fed on “ekpan nkukwo” which had the highest serum zinc value. There was a significant difference (p
