The provision of nutrient-dense complementary foods is essential to ensure aninfant’s nutrient requirements are met. Yet often, relative to recommendations, traditionalcomplementary foods have low levels of nutrients, suggesting a role, for fortifiedmanufactured baby foods, in ensuring dietary adequacy. In this review, the potentialbenefits and safety of using fortified manufactured baby foods versus traditional foodsalone are evaluated based on evidence from food composition data, diet modeling andintervention studies. Results from the food composition data and diet modeling suggestthat ensuring a nutritionally adequate complementary feeding diet based on traditionalfoods alone is difficult. Conversely, except for biochemical iron status,intervention trials do not show consistent benefits, for growth or biochemical zinc orriboflavin status, with the use of fortified manufactured baby foods versus traditionalfoods alone. The safety of manufactured baby foods will depend on food preparationpractices and the presence of effective governmental regulatory infrastructures.Hence, in environments where fortified manufactured baby foods are expensive,unavailable or where there is an absence of effective governmental regulatory infrastructures,the use of traditional foods is advised. Conversely, where affordable manufacturedbaby foods are available, marketed safely and fortified appropriately, theiruse is likely to result in improved nutrient intakes and infant biochemical iron status.In all environments, the promotion of breastfeeding, active feeding and high levels ofhygiene is essential to ensure optimal nutritional status.
