Having the quality of preventing or opposing beriberi, a disease caused by vitamin B1 deficiency.
From anti- (against) + beriberin (relating to beriberi). Beriberi comes from Sinhalese beri (weakness). This term emerged in early 20th-century nutrition science when researchers discovered vitamin B1's role in preventing the disease.
Beriberi was a mysterious disease that plagued sailors and people eating white rice until scientists discovered it was just missing vitamin B1! Foods like whole grains and meat are naturally antiberiberin—they prevented the disease long before anyone understood why.
