Cassava (Manihot esculenta), also called singkong, manioc, yuca, balinghoy, mogo, mandioca, kamoteng kahoy, and manioc root, a woody shrub of the Euphorbiaceae (spurge family) native to South America, is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy, tuberous root, a major source of carbohydrates. It differs from the similarly spelled yucca, an unrelated fruit-bearing shrub in the Asparagaceae family. Cassava, when dried to a starchy, powdery (or pearly) extract is called tapioca; its fermented, flaky version is named garri.
Cassava is the third-largest source of food carbohydrates in the tropics, after rice and maize.[1][2] Cassava is a major staple food in the developing world, providing a basic diet for over half a billion people.[3] It is one of the most drought-tolerant crops, capable of growing on marginal soils. Nigeria is the world's largest producer of cassava.
Cassava root is a good source of carbohydrates, but a poor source of protein. A predominantly cassava root diet can cause protein-energy malnutrition.[4]
Cassava is classified as sweet or bitter. Like other roots and tubers, cassava contains antinutritional factors and toxins.[5] 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.[6] Nevertheless, farmers often prefer the bitter varieties because they deter pests, animals, and thieves.[7] The more-toxic varieties of cassava are a fall-back resource (a "food security crop") in times of famine in some places.
