VIII. Boys and Girls at the Waldorf School

Suppose children show an extreme form, a pathological form of what we call the melancholic disposition; or suppose you get an extreme form, a pathological form of the sanguine temperament. The teacher must know, then, where the border-line comes between what is simply physical and what is pathological. If he observes that a melancholic child is tending to become pathological,—and this is far more often the case than one would think,—he must get into touch with the child's parents and learn from them what diet the child as been having. He will then discover a connection between this diet and the child's pathological melancholy. He will probably find,—to give a concrete instance, though there might be other causes,—he will probably find that the child has been getting too little sugar in the food he is given at home. Owing to lack of sugar in the food he gets, the working of his liver is not regulated properly. For the peculiarity of the melancholic child is that a certain substance i.e. starch, (German: Starke) is formed in the liver indeed, but not formed in the right measure. This substance is also to be found in plants. All human beings form starch in the liver but it is different from plant starch—it is an animal starch which in the liver immediately becomes transformed into sugar. This transformation of animal starch into sugar is a very important part of the activity of the liver. Now, m the melancholic child this is out of order, and one must advise the mother to put more sugar into the child's food; in this way one can regulate the glycogenic activity of the liver,—as it is called. And you will see what an extraordinary effect this purely hygienic measure will have.
