The physical, social and intellectual development of children from conception to the end of adolescence requires an environment that is both protected and protective of their health. A growing number of dis- eases in children are linked to unsafe environments. Prenatal and early life exposures, including diet, are associated with child health and human development and predispose to late adult effects. Thus, the INMA project is based on three main rationales. First, exposure to environmental pollutants through air, water and food is worldwide. Children are espe- cially vulnerable to its effects as they are not just little adults, they are still growing, and their immune sys- tem and detoxification mechanisms are not fully.
