[Nutrition and inflammatory bowel disease].

In this paper, the causes and consequences of nutritional deficiencies in inflammatory bowel disease are reviewed. Particular emphasis is made on their pathophysiological implications. In addition, the basis for nutritional intervention in these patients are described (both in terms of dietary counseling and the use of specialized nutritional support). Particular mention is made on the current evidences in favour of a primary therapeutic role of artificial nutrition and some specific nutrients in Crohn's disease.
