II. Nutrition
It is indeed very peculiar that today science teaches that not 120 grams of protein are necessary, but only 20 to 50 grams. That is the amount, they say, that a person actually needs daily. In just two decades, science has so quickly changed its views. So you can see how little you can actually rely on when something is supposedly scientifically established. If you happen to need to inform yourself on this subject and you pick up a twenty-year-old encyclopedia, you will read in the relevant chapter that you need 120 grams of protein. If you get a later edition, you will read: 20 to 50 grams, and if you had more, you would become ill from it. So you see what the situation is with scientific truths. We are taught what is to be considered true or false depending on which edition of the encyclopaedia we get hold of. All this just goes to show that you cannot get a clear idea of such things, which go into the spiritual, at all in this way. And that is of course a reason, when one really considers the matter, to go into the spiritual, when one wants to understand what happens when man takes in egg white. But it is that food, which must still be processed in the intestines, in the abdomen, and the abdomen itself must have the strength to process this egg white. You know that protein, especially fresh egg white, is semi-liquid. All protein is semi-liquid. The human etheric body has access to all semi-liquid substances. The human etheric body cannot do anything with solid substances, only with liquid ones. So the human being must take all the food he consumes in a liquid state.
