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.

Zinc Absorption From Biofortified Rice
Bioavailability of Zinc From Rice Biofortified With 70Zn and Rice Extrinsically Labeled With 70Zn in Young Adults: a Randomized, Single-blind Study

One of the newest strategies to combat micronutrient deficiencies is the biofortification of staple foods, where higher levels of minerals are obtained through breeding of staple crops. The aim of this study is to evaluate zinc absorption from a rice biofortified with zinc when compared with a control rice fortified with zinc just before consumption.
