III. On Nutrition

Now let us speak about protein. The presence of protein is essential from the very outset. It is present in the egg before a human being or an animal comes into existence. We can therefore say that protein is the substance which really builds up the human body and is the basis upon which it develops; it is the primary and fundamental substance out of which everything else in the body must unfold. Protein is present in the mother's womb as a tiny egg; the fertilisation of the egg enables the protein to become the basis of the human body. But man needs protein all the time; it must be a constituent of his regular food. If his organism contains too little protein, or he cannot thoroughly digest it, he will gradually waste away; but if at any moment of his life he were without protein he would immediately die. Protein is essential both for the beginning of existence and for man's very life. Absence of protein means death.
