Current and potential contributions of large-scale food fortification to meeting micronutrient requirements in Senegal: a modelling study using household food consumption data.

Introduction: Micronutrient deficiencies are common among women of reproductive age (WRA) and children in Senegal. Large-scale food fortification (LSFF) can help fill gaps in dietary intakes.

Methods: We used household food consumption data to model the contributions of existing LSFF programs (vitamin A-fortified refined oil and iron and folic acid-fortified wheat flour) and the potential contributions of expanding these programs to meeting the micronutrient requirements of WRA (15-49 years) and children (6-59 months).
