The paper highlights that both vegetarians and vegans, including athletes, are able to meet and often surpass their protein needs without consuming meat. This challenges the common belief that one must eat animal products to obtain enough protein. Instead, the evidence shows that plant-based diets can support optimal protein levels.

Furthermore, the notion that a high intake of animal protein is beneficial is increasingly questioned, as studies indicate that excessive consumption may lead to serious health issues such as osteoporosis, kidney disease, calcium stones, and certain cancers. Thus, a plant-based diet not only meets protein requirements but may also contribute to better overall health outcomes compared to diets that are rich in animal proteins.
