Micronutrient (MN) deficiencies cause a considerable burden of disease for children in many countries. Dairy products or cereals are an important food component during adolescence. Fortification of dairy products or cereals with MN may be an effective strategy to overcome MN deficiencies, but their specific impact on health in this age group is poorly documented.We performed a systematic review and meta-analysis (registration numberCRD42016039554) to assess the impact of MN fortified dairy products and cereal food onthe health of children and adolescents (aged 5–15 years) compared with non-fortified food.
