[Nutritional problems among adults in the Sahel].

A definite list of nutritional diseases can be ascribed to the adult people who live in the Sahel. It results from a food consumption rate which, though a decent energetic or caloric level, remains of little values because of some protein, trace element and vitamin deficiencies. Subclinical diseases that can only be detected through routine mass-examinations, are prevalent. But on the other hand, clinical diseases, the most typical and the most frequent of which is nutritional anemia, are of very frequent occurrence too. The usual disturbing factors of the precarious states of nutrition are pregnancy and lactation, the season of the gap and the associated infections.
