The Resilient Superfood From Poisonous Roots

Tapioca comes from cassava, a hardy tropical shrub that thrives in soil so poor other crops would fail. Amazingly, the raw roots contain cyanide and must be carefully processed to become the chewy starch we enjoy in bubble tea.

Native to Brazil, the cassava plant is a true survivor that can grow in nutrient-depleted dirt where most vegetation dies. To protect itself from pests, the plant stores toxic cyanide compounds, making raw consumption dangerous for humans. Farmers must soak, ferment, or cook the tubers extensively to remove these toxins safely. This clever survival mechanism explains why the plant has become a vital food staple for millions across tropical regions.
