Despite their name, the most significant exporter of Brazil nuts is not Brazil but Bolivia, where they are called almendras. In Brazil, these nuts are called castanhas-do-pará (literally “chestnuts from Pará”), but Acreans call them castanhas-do-acre instead. Indigenous names include juvia in the Orinoco area.
In the United States Brazil nuts were, until the 1960s, known by the epithet “nigger toes,” though the term fell out of favor as public use of the racial slur became increasingly unacceptable. They can be seen being sold in a market under this name in a scene from the 1922 Stan Laurel film The Pest.
