Can a human live without protein?

Fortunately, protein can be found in non-animal sources, such as lentils, beans, and whole grains. Briefly going over the role protein plays in the body shows humans cannot live without it. All humans need it to survive, and that’s the reason why protein is described as the ‘building blocks of life’.
