During the 3-day baseline period, each patient will receive their usual enteral tube feeding prescription as determined by their dietitian. Following the 3-day baseline period, all patients will enter the 90-day intervention period, where they will receive one (or a combination) of the plant-protein dominant feeds.

During the 3-day baseline period, each patient will receive their usual enteral tube feeding prescription as determined by their dietitian. Following the 3-day baseline period, all patients will enter the 90-day intervention period, where they will receive one (or a combination) of the animal-protein dominant feed (control) daily.

Patients randomised to the Intervention Group will continue their existing tube feed for 3 days (baseline period) after which they will then receive one (or a combination) of the 4 plant-protein dominant enteral feeds (1kcal/ml or 1.5kcal/ml, with or without fibre) for 3 months. Patients who chose to remain on the study feed following the duration of the trial will be invited to participate in the full 12-month follow up (an additional 9 months), where data will be collected at 6- and 12-months. The feed prescription will be determined on an individual basis by the dietitian responsible for the patient's nutritional management but will be a minimum of 500ml feed per day (providing ≥500kcal).

A standardised gastrointestinal (GI) tolerance questionnaire to capture perceived severity (none, mild, moderate or severe) of common gastrointestinal symptoms (diarrhoea, constipation, bloating, abdominal discomfort, vomiting and nausea).

Acceptability (e.g., liking, ease of use, preference) will be assessed by a questionnaire. Questions will be rated on a 7-point Likert scale (1 strongly disagree - 7 strongly agree)

Compliance with the study product prescription (%) will be assessed daily by recording how much of the study product was prescribed compared to the amount administered.

A 24-h dietary recall will be conducted to record all food, drink and nutritional feeds taken in the 24 hours prior for analysis of daily nutritional intake i.e., total energy intake (kcal/day) and macro- and micronutrients (g/day or mg/day).

Body weight (kg) will be measured using standard methods to the nearest 0.1kg using a weighing scale without heavy clothing. Height and weight measures will be used to calculate body mass index (BMI) as kg/m^2.
