In developing countries, complementary foods are based on local cereal porridges. These foods are poor in trace elements, with a high risk of inducing micronutrient deficiencies-the primary cause of mortality in children under the age of five. Inappropriate feeding of complementary foods is the major factor creating malnutrition and micronutrients deficiencies in Cameroon children, as well as in other developing countries. This study determined the zinc and phytate content of 30 complementary foods that were based on maize or Irish potatoes. The foods were blended or treated by dehusking, fermentation and germination. Zinc was measured by flame atomic absorption spectrophotometry and phytates by high pressure-liquid chromatography; then phytates/zinc molar ratios were calculated. Concentrations (mg/100g dry matter) ranged, respectively, from 0.20 to 2.58 (0.12±0.67) for zinc and from 0.00 to 6.04 (1.87±1.7) for phytates. The phytate/zinc ratio varied from 0.00 to 51.62 (11.12±11.53). It appears that germination and fermentation reduced the level of phytates: however, zinc levels in the samples did not change significantly. The traditional, local complementary foods were not only poor in zinc, but contained very high levels of phytates. These phytates have the potential to considerately reduce the acid extraction of zinc, and could impair its bioavailability.
