Cooking banana (matoke), dry cassava chips, sorghum, millet, beans, and white maize are important food commodities for Ugandans. The staple food varies by region. Matoke is most important in the central, western, and southwestern regions; millet in the east; and sorghum in the east, north and northeast. Cassava chips, beans, and white maize are also very important for a significant part of population; cassava chips are especially important in eastern (Soroti), northern, and northwestern (Arua) Uganda. In Mbarara and Kampala, matoke is most important commodity for all households. Lira and Soroti depend heavily on sorghum and millet and also represent a supply source for Karamoja. Beans are consumed across the country, but monitored in Kampala and Lira: the latter of which is also a production area. Masindi is a production and commercial area for white maize.
