Such an awe-fully bad thinking in this field-these specialists are scary-very bad in common sense psychology-throwing all these fuzzy 'opinions' out. Previously even a lack of zinc was cause..now -you can use that to explain everything these days-Genetics? so (grand) mom or -dad had anorexia ..now the child too? Show it !..Why does Anorexia arise predominantly in middle class?, mostly in the west or qua motivated by western cultures like Japan..and has a typical family psychology-emotionality at base.
