Vitamin, mineral and trace element intakes were assessed in a rural African population using a novel dietary survey method, and compared with status measurements. In addition to the previously described protein deficiency, multiple micronutrient deficiencies were observed. Although vitamin A intakes were generally satisfactory, some low plasma retinol concentrations were observed in adults, due perhaps to the very low protein intakes or infectious diseases. Vitamin B1, B2 and niacin intakes were clearly inadequate, and for the two former were confirmed by status measurements. Whilst B6 intake was low, B6 status was adequate, probably resulting from lower requirements because of low protein intakes. B12 intake was low in some age groups, whereas that of folate was satisfactory. Fe, Cu and Mg intakes appeared to be adequate. Intakes of phosphorus and iodine were low for children and adolescents; those of Zn and Ca were clearly inadequate, except for Zn in women. Dietary interventions to prevent or treat malnutrition in this region should address several micronutrients in addition to protein.
