Plant-based versus animal-based oral nutritional supplements

PlAnt Vs Animal Based Oral Nutritional Supplements: Patients' Opinions and Nutritional Outcomes: A Multicenter Pilot Feasibility Study

NA · Radboud University Medical Center · NCT07399886

We're testing whether plant-based nutrition drinks work as well as animal-based drinks for hospitalized adults at high risk of malnutrition.

What this trial studies

Hospitalized adult patients at two Dutch university medical centers will receive one of two oral nutritional supplements (a plant-based Fresubin vanilla or an animal-based Fresubin Yodrink raspberry) and be followed for three months. Baseline and three-month measurements include weight, height, body composition by bioelectrical impedance (BIA), muscle thickness by lumify ultrasound, handgrip strength, SPPB and TUG physical performance tests, quality-of-life and dietary questionnaires, and a 3-day food diary. Participants will log daily ONS intake, be contacted at one and two months to review intake and any changes, and complete an interview after three months about their experiences. The trial focuses on feasibility and physiological and functional nutrition outcomes in usual-care inpatient settings among patients advised to take at least two ONS bottles daily.

Who should consider this trial

Good fit: Hospitalized adults (≥18 years) treated at Radboudumc or Maastricht UMC+ who are judged at high risk of malnutrition and advised to take at least two bottles of ONS daily are the intended participants.

Not a fit: Patients who are tube- or parenteral-nutrition-dependent, receiving only palliative care, lactose- or soy-intolerant, strictly vegan, unable to follow study procedures, or who used ONS in the prior six months are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If plant-based ONS perform similarly to animal-based ONS, patients could receive comparable nutrition while allowing hospitals to offer more sustainable, lower-carbon nutrition options.

How similar studies have performed: Direct head-to-head comparisons of plant- versus animal-based ONS in hospitalized patients are limited, so evidence for equivalent clinical benefit is still sparse.
