Zinc Absorption From Fortified Water

A water purifying system, called LifeStrawFamily (LSF), able to fortify water with zinc to a concentration of 4 mg/l has been developed. The aim of this study is to investigate whether the LSF strategy is advantageous in terms of zinc absorption compared to food fortification. This study wants to demonstrate whether aqueous zinc produced by the LSF device consumed within or outside meals is better absorbed than zinc from an enriched cereal-based staple food in healthy adults. In addition, the zinc absorption from the LSF-enriched water and from a fortified inhibitory cereal-based pudding will be compared.
