The study feed is a high energy (1.5kcal/ml), high protein (7.5g protein/100ml) peptide-based feed, available as a 500ml enteral tube feed, and a 200ml Vanilla-flavour oral nutritional supplement. However, the tolerance, compliance and acceptability of this feed is unknown in this patient group who have complex clinical conditions. Therefore this study is required to assess gastrointestinal tolerance, compliance and acceptability of this high energy density (1.5kcal/ml), high protein (7.5g/100ml), peptide-based feed in community patients requiring nutrition support in clinical practice.
