ABSTRACT:This study focuses on the intake of vitamin A from staple foods that are or could be fortified using a survey conducted in three major cities in Ghana. The study distinguishes among consumption frequencies, i.e., daily, weekly, and monthly, of five staples (wheat and maize flour, groundnut oil, palm oil, and vegetable oil). A multivariate probit technique estimates three sets of five equations accounting for the consumption of five staples in three time periods (daily, weekly monthly). The correlations across equations were tested indicating the suitability of the selected estimation approach. The results suggest that per capita income, geographic location, employment status, education, and market access are important in determining consumption frequency. The results also reveal that the existing source of vitamin A from the food fortification program is insufficient for Ghanaian women to reach the WHO daily standard. Fortifying maize flour (in addition to already fortified vegetable oils and wheat flour), a staple, will largely alleviate the inadequate vitamin A intake among urban households.
