Study Summary

Bioavailability of iron and zinc from habitual plant-based diets consumed by young children in Mexico is low due to the high phytate content. Whey protein has been found to increase zinc absorption, thus, providing a whey based supplement with micronutrients may be an effective strategy to increase iron and zinc bioavailability from plant-based foods and alleviate iron and zinc deficiencies. The investigators compared absorption of zinc and iron in children receiving diets with and without whey protein supplements (WPS).

Primary Outcome

Absorption of zinc was compared in young children when given a habitual diet with and without a whey protein supplement. Fractional absorption of zinc for a day was measured by extrinsic labeling with stable isotopes of zinc. Fractional absorption of zinc was measured by a dual isotope tracer ratio technique. Measurement of total zinc in duplicate diets on test day will allow determination of quantity of this micronutrient absorbed (mg/d).
