The nutritional therapy aims to maintain or recover the nutritional status, and the enteral nutrition therapy is used when
oral feeding is not indicated or when the individual’s nutritional needs are not met. During hospitalization, nutritional status
impairment may be fast, and malnutrition increases the risk of complications and mortality. Enteral formulas can be composed of
plant or animal proteins, but it is not clear whether different sources influence in clinical outcomes. Considering the lack of studies
addressing this topic, evidence related to the type of protein source in enteral nutritional therapy was compiled in order to identify
differences in clinical outcomes of patients using nutritional therapy. Studies that were included in the review show that the use
of enteral formulas based on vegetable protein appear to be as efficient as animal protein based formulas, regarding maintenance
of nutritional status, improvement of glycemic control and minimizing gastrointestinal complications when compared to animal
protein. The limited number of studies and differences in study design and characteristics make it difficult to draw evidence-based
conclusions. Thus, further studies are needed to elucidate the role of vegetable protein in clinical outcomes when compared to
