Particularly in developing countries nearly one billion people are effected by nutrition insecurity in form of under- or malnutrition (FAO 2010, p. 1). Merely by the expression of vitamin A-deficiency an estimate of up to 500,000 children go blind worldwide every year (WHO 2011). This bachelor thesis deals with a solu-tion approach in form of the contribution made by the orange-fleshed sweet potato (OFSP) and its afford towards nutrition security in rural areas of Mwanza, Tanzania. With help of the partner organization TAHEA, a retrospective population-based study of the nutritional status of rural population of Mwanza was conducted and impressions on food security were reinforced through participant observation. The positive influence of OFSP towards vitamin A status has been confirmed and among others an income-generating function by cultivation and sale of the tuber has been observed. The risk of a possible overdose must also be considered. Thus, the tuber is recommended as a nutritious snack or side dish, but should not be advertised as a considered staple food.
