Lipid-based nutritional supplements and fortified blended flours are widely used to increase nutrient density of children's diets and improve health. Due to their small stomach size and rapid growth velocity, infants need higher nutrient density foods than do other family members. While foods premixed with fortificants can meet infant needs, their effectiveness is compromised by displacement of other food. Fortified cereals improve diet quality more than other supplementation strategies by displacing plain cereal without altering breastfeeding or other intakes.
