Rating (out of 5): 4

Animal protein is scientifically validated as beneficial in supporting healing after surgery. Post-surgical healing is a physiologically demanding process that requires increased protein intake for tissue repair, immune function, and maintenance of lean body mass. Numerous clinical guidelines and studies recommend higher protein intake for post-operative patients to support wound healing and recovery. Animal proteins (such as those from meat, fish, eggs, and dairy) are considered “complete” proteins, providing all essential amino acids necessary for tissue synthesis. Research has shown that adequate protein intake reduces the risk of complications such as infection, delayed healing, and muscle wasting. Systematic reviews and meta-analyses have demonstrated that protein supplementation, especially from high-quality animal sources, improves outcomes such as wound healing rates and functional recovery in surgical patients. While plant proteins can also contribute, animal protein sources are often preferred in clinical settings due to their amino acid profile and digestibility. Overall, the use of animal protein to support healing after surgery is strongly supported by scientific evidence and is a standard part of nutritional management in surgical care.
