[Oral nutritional supplements. Are they useful?].

Oral nutritional supplements are products included in enteral nutrition, preferably used in hospital settings, although their use in the community is gradually increasing and in the United Kingdom has doubled in the last seven years, with prescriptions covering a wide range of the population from children to the elderly, and different pathologies affecting their nutritional status. There is, however, no consensus on the usefulness of oral nutritional supplements among these patients, so we do not have any recommendations for use. In this paper we have reviewed the various studies available in the literature in order to clarify the usefulness of these supplements in different contexts or pathologies.
