56 Back up Iron: Pro-oxidant, transition (of electrons) metal. Hepcidinis a peptide expressed predominantly in liver. Hepcidinregulates intestinal iron absorption, plasma iron concentrations, and tissue iron distribution by inducing degradation of its receptor, the cellular iron exporter ferroportin. Ferroportinexports iron into plasma from absorptive enterocytes, from macrophages that recycle the iron of senescent erythrocytes, and from hepatocytes that store iron.

57 Conclusions Educate parents toevaluate/understand: Their children s weight status Their children s nourishment status That increased body weight is no way a sign of good nourishment The importance of all food groups: - Diary ( enriched milk, yogurt, cheese) -Protein food ( meat, fish) -Fruit -Vegetable - Cereals and starch ( enriched whole grain) Seek for opportunities for sun exposure and outdoors activities.
