The Strange Case of BeriBeri
In 1887 a strange nerve disease attacked the people in the Dutch East Indies.
The disease was beriberi. Symptoms of the disease included weakness and
loss of appetite, victims often died of heart failure. Scientists thought the
disease might be caused by bacteria. They injected chickens with bacteria from
the blood of patients with beriberi. The injected chickens became sick.
However, so did a group of chickens that were not injected with bacteria.
One of the scientists, Dr. Eijkman, noticed something. Before the experiment,
all the chickens had eaten whole-grain rice, but during the experiment, the
chickens were fed polished rice. Dr. Eijkman researched this interesting case
and found that polished rice lacked thiamine, a vitamin necessary for good
health.
