III. On Nutrition

You know that man consists of physical body, ether body, astral body and “I” but these members of his being do not interact in the same way at every age of life. Until the age of seven, ether body, astral body and the “I” are still only making their way down into the physical body of the child. When the ether body has penetrated fully into the physical body, the second teeth appear; when the astral body has penetrated fully into the physical body, puberty is reached. Therefore if potato food taken in excess has made it difficult for the soul-and-spirit to enter into the embryo in the real sense, this will also have an injurious effect upon what happens at the age of 14 or 15. All through his life such a human being will go about as if his body did not really belong to him, as if it were hanging about him like a bag. The effect of too much potato food may therefore be that human beings are born without sufficient strength to cope with life and its demands.
