  Purpose

Assessment of zinc absorption from a phytic acid rich complementary food, consumed by young children immediately after the addition of the enzyme phytase. A randomized single blind study


Condition
Study Not Related to a Disease. Nutrition Study Without Drug Administration.

Study Type: Observational
Official Title: Assessment of Zinc Absorption From a Phytic Acid Rich Complementary Food, Consumed by Young Children Immediately After the Addition of the Enzyme Phytase. A Randomized Single Blind Study

Further study details as provided by Swiss Federal Institute of Technology:

Primary Outcome Measures:
  • Fractional absorption of zinc [ Time Frame: 33 days ] [ Designated as safety issue: No ]
    Fractional absorption of zinc is estimated by using the double isotope tracer ratio technique by administering 67Zn as oral and 70Zn as intravenous stable isotopes.The urinary enrichment with both isotopes is measured in a spot urine sample by inductively coupled plasma mass spectrometry.
