Sweetpotato (Ipomoea batatas) is a highly productive food crop, high in carbohydrates and vitamin A. It has few natural enemies and is widely grown in some countries of Africa where vitamin A deficiency (VAD) is prevalent and contributes to high rates of premature death, especially in children and pregnant women. Orange-fleshed sweetpotato is a good source of beta carotene, one of the most important precursors of vitamin A in the human diet, which also has anti-oxidant properties.
From 2005 to 2008, the Quality and Nutrition Laboratory has chemically analyzed the ß-carotene and mineral concentration of more than 500 sweetpotato varieties grown in different environments.
