Enteral Feeds: Benefits and Drawbacks Associated with Blenderized Feeds and Commercial Formulas—A Narrative Review

Enteral feeds can be classified as two major types: commercial enteral formulas and blenderized enteral feeds. When deciding the most appropriate type of feed for a patient, several parameters need to be taken into consideration. Benefits associated with the use of blenderized tube feeds include giving a sense of normalcy to patients, having a positive impact on anthropometric indices, allowing for careful control over known food allergens, being associated with improved gastrointestinal tolerance and improved gut microbial composition (mainly in pediatric populations) and being generally less costly compared with commercial formulas. On the other hand, commercial enteral formulas have the advantages of being generally sterile, less likely to cause tube clogging and having a known and consistent nutrition composition. Further studies, specifically well-designed randomized controlled trials including adult populations, that will emphasize the impact of blenderized enteral feeds on various clinical outcomes are warranted. Clinicians need to be conscientious and educated regarding safe food practices for blended food preparation, as well as the characteristics of commercial formula options available to help assist patients in selecting the proper feed for their nutritional needs and clinical condition.
