Fluid diet - elemental

This document is part of the ACI Diet Specifications for Adult Inpatients. It is not to be used for patient education.

Aim

To provide nutrients as small molecular weight compounds, i.e. proteins as amino acids or peptides, carbohydrates as oligosaccharides or monosaccharides, and fats as medium-chain triglycerides.

Characteristics

All nutrition provided by commercial elemental nutritional supplement drinks.

Indications

The treatment of some gastrointestinal diseases, eg Crohn’s disease, pancreatitis, irritable bowel syndrome.

Nutritional adequacy

Palatability limits compliance with this diet and patients may not be able to meet their energy needs with an elemental sip feed. Polymeric formulas may be better accepted and as effective as elemental fluid diets. Exclusive extended use of elemental formulas can result in essential fatty acid deficiency.

Precautions

Patients do not receive a menu.

Paediatrics

Suitable for use in paediatrics when combined with an age-appropriate diet.
