Analysis of nutrients to develop new or update food composition database is costly and time consuming. An alternate approach is to add the data on nutrients from existing literature using guidelines set by International Network of Food Data Systems (INFOODS). The currently available database for food composition in Pakistan is fairly old (2001) and thus, needs to be updated. In the present study mineral content of various foods from Pakistan was collected from existing literature and scrutinized against a set of criteria for inclusion in updated food composition database of Pakistan. Data for 37 food items with eight minerals (calcium, iron, zinc, phosphorus, magnesium, potassium, sodium and copper) fits under the criteria therefore is included in updated database for foods of Pakistan. Additionally, chromium, cobalt, cadmium, lead, nickel and manganese were also updated for 16 food items. Further, selected mineral content (iron, zinc, phosphorus and calcium) was compared with food composition Table of Pakistan (published in 2001). Comparison results showed that mineral content for most of the foods vary among two databases. The present study demonstrates feasibility of updating food composition databases thorough scientific reports on food products of a particular country.
