Konzo: A Little-Discussed Disease

Cyanide affects the nervous system, causing sudden weakness in the legs and possible permanent sequelae.
How to Make Cassava Safe
1. Peel thoroughly
The peel holds most of the toxins. Remove it completely.
2. Soak or Ferment
Grate or peel the root and cover it with clean water for 24–48 hours. In Northern Brazil, farinha d’água (cassava flour) follows this method.
3. Cook until tender
4. Combine with protein
