Thiamine deficiency is a medical condition of low levels of thiamine (vitamin B 1). [1] A severe and chronic form is known as beriberi. [1] [7] The name beriberi was possibly borrowed in the 18th century from the Sinhalese phrase බැරි බැරි (bæri bæri, “I cannot, I cannot”), owing to the weakness caused by the condition.
Wernicke encephalopathy (WE), also Wernicke's encephalopathy, [1] or wet brain is the presence of neurological symptoms caused by biochemical lesions of the central nervous system after exhaustion of B-vitamin reserves, in particular thiamine (vitamin B 1). [2]
The group that ate only white rice documented 161 crew members with beriberi and 25 deaths, while the latter group had only 14 cases of beriberi and no deaths. This convinced Takaki and the Japanese Navy that diet was the cause of beriberi, but they mistakenly believed that sufficient amounts of protein prevented it. [65]
In 1897, Vorderman visited all of the around 100 prisons on the island of Java. He took samples of the prison rice and examined the prison records to determine the number of beriberi cases. He kept the real purpose of his visits secret so that word did not get around the Chinese rice suppliers and lead them to change the type of rice they provided.
During his time there, he discovered that Beriberi, which was commonly believed to be caused by external forces, was caused by a lack of thiamine in the human body. This led to a Nobel Prize for Physiology or Medicine for Eijkman in 1929.

At the time, beriberi (considered endemic to Japan) was a serious problem on warships and was affecting naval efficiency. Takaki knew that beriberi was not common among Western navies. He also noticed that Japanese naval officers, whose diet consisted of various types of vegetables and meat, rarely suffered from beriberi.
