Malnutrition is frequent in the north of Ivory Coast, catching 63,7% of the children admitted in the Korhogo hospital, 39% of the children in the out-patients services, 25% of the children living in villages and 6,9% of the admitted adults. We note animal protein and lipid deficiencies mainly. Syndrome of protein deficiency is very well known, but lipid deficiency is less; its responsibility in peripheral neuropathy, as hypothesis, is recalled. Fish and butcher's meat protein consumption remains stable, because of the economic context. Hunting meat consumption remains stable and important. Lipid intake is also under economic and cultural constraints. Development projects, and difficulties are briefly exposed.
