08
Fortification of staple foods with iron can reduce anemia by a pooled 30% in children (meta-analytic estimate reported in a peer-reviewed review), supporting fortification’s measurable impact.
09
The 2022 UNICEF/WHO global update indicates that breastfeeding promotion could prevent a substantial share of child undernutrition outcomes; exclusive breastfeeding rates are a key driver, and global estimates show only 40% of infants are exclusively breastfed (measurable behavior outcome).

Interpretation
Outcomes & Impact Interpretation
Across outcomes tied to child nutrition, the evidence consistently shows measurable real world gains, such as about a 12% reduction in child mortality from vitamin A and roughly a 32% cut in childhood anemia from iron supplementation, alongside policy and program pathways that can lift behaviors and well being like 91.9% school compliance with Offer versus Serve and school feeding improving attendance by around 9%.
