2. Cassava
Cassava is only known as tapioca in many parts of the world, and it is largely consumed as a family staple in Africa. Cassava is also a rich source of starch, and other substances. It can be eaten boiled, made into chips, or converted to several kinds of household meals. But hold on! Scientific research suggests the crop is high in linamarine and its tuber is rich in cyanide – an organic compound that could be very poisonous and quite deadly to consumers.
