[Options in dietary treatment by oral and parenteral balanced nutrition (author's transl)]

Balanced nutrition is an important tool in the treatment of several pediatric disorders. Its application is based on the knowledge of normal metabolism and of the pathophysiology in metabolic disorders. The principles of oral balanced dietary treatment are discussed in relation to phenylketonuria and renal insufficiency. In case of unability to ingest foods by the oral-enteral route parenteral nutrition becomes necessary. The indications, principles and hazards of parenteral nutrition are discussed, especially the type of amino acid solution required. It is pointed out that xylit and sorbitol containing solutions should be abandoned completely since there are no indications for its use but potential hazards by toxic side effects.
