A June 2021 paper by University of Arkansas for Medical Sciences and colleagues said

  • "Our research illustrates that animal-based protein foods, such as beef, eggs and pork, and plant-based protein foods, such as kidney beans, peanut butter, tofu and mixed nuts, cannot be considered to be equivalent, or a substitute for each other, when developing healthy dietary patterns, given their unique physiological effects," 

  • "While it's well-established that animal proteins can more readily provide essential amino acids than plant protein foods, our study also indicates that eating animal protein foods such as beef, pork and eggs may lead to increased protein synthesis, which has been shown to have benefits such as improved satiety and lean muscle mass maintenance."
