Although Eijkman had been sent to Indonesia to study beriberi, the discovery of the cause was accidental. He noticed the symptoms in some chickens used in his laboratory when their feed had been altered temporarily. Later he determined that polished rice lacked the dietary component found in unpolished rice.
ChristiaanEijkman was the seventh child of Johanna Alida Pool and ChristiaanEijkman, a boarding-school proprietor in the small Gelderland town of Nijkerk, situated at the northern border of the Veluwe region.
Eijkman now supposed that the causative factor must be sought in the food, especially the polished and boiled rice.
Eijkman discovered that the real cause of beriberi was the deficiency of some vital substance in the staple food of the natives, which is located in the so-called "silver skin" (pericarpium) of the rice.
