RESEARCH POSTER PRESENTATION DESIGN © 2012 www.PosterPresentations.com Vitamin A deficiency (VAD) is a major public health problem in the Democratic Republic of Congo (DRC) and just as in other developing countries, provitamin A carotenoids (pVACs) from plants are the main source of vitamin A for most rural-agriculture dependent households. Bananas (East African Highland bananas and plantain) are among the predominant crops grown in Eastern DRC where they form a major part of the diet. Studies on bananas from Hawaii and the Philippines indicate that   bananas could be good sources of micronutrients especially pVACs, it is therefore necessary to assess the potential contribution of Musa cultivars grown in Eastern DRC in fighting VAD.
