Orange sweet potato (OSP) is an extremely rich source of provitamin A that has been proven to improve the vitamin A status of children, and to reduce the likelihood and duration of diarrhea. Children with vitamin A deficiency are at increased risk of severe morbidity from common childhood infections such as diarrheal diseases and measles. In cases of extreme deficiency, they can become blind. Sweet potatoes that are high in provitamin A can provide up to 100% of daily Vitamin A needs and contribute to a reduction in vitamin A deficiency in regions where daily sweet potato consumption is high. More than 95% of the world’s sweet potato crop is grown in developing countries. African farmers produce about 7 million tons of sweet potatoes annually.
