Cassava (Manihot esculenta), also called manioc or tapioca root, is cultivated as an annual crop in tropical and subtropical regions for its edible starchy, tuberous root. Cassava, when dried to a powdery extract, is called tapioca. Cassava is the third largest source of food carbohydrates in the tropics, after rice and maize. Cassava is a major staple food in the developing world, providing a basic diet for over half a billion people. It is one of the most drought-tolerant crops, capable of growing on marginal soils. Like other roots and tubers, both bitter and sweet varieties of cassava contain antinutritional factors and toxins. It must be properly prepared before consumption. Improper preparation of cassava can leave enough residual cyanide to cause acute cyanide intoxication and goiters and may even cause ataxia or partial paralysis.
