Brazilian cuisine has European, African and Amerindian influences. It varies greatly by region, reflecting the country's mix of native and immigrant populations, and its continental size as well. This has created a national cuisine marked by the preservation of regional differences.
Ingredients first used by native peoples in Brazil include cassava, guaraná, açaí, cumaru and tacacá. From there, the many waves of immigrants brought some of their typical dishes, replacing missing ingredients with local equivalents. For instance, the European immigrants (primarily from Portugal, Italy, Spain, Germany, Poland and Switzerland) were accustomed to a wheat-based diet, and introduced wine, leaf vegetables, and dairy products into Brazilian cuisine. When potatoes were not available they discovered how to use the native sweet manioc as a replacement. The African slaves also had a role in developing Brazilian cuisine, especially in the coastal states. The foreign influence extended to later migratory waves - Japanese immigrants brought most of the food items that Brazilians would associate with Asian cuisine today, and introduced large-scale aviaries, well into the 20th century.
