Absorption of Zinc from Mixed Diets Containing Conventional Bangladeshi Rice, Zinc-Biofortified Bangladeshi Rice, or Conventional Bangladeshi Rice with Added Zinc among Young Children from a Peri-Urban Community in Bangladesh.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this clinical study publication.

To measure the amount of TAZ by young Bangladeshi children from Hi-Zn BfR, Lo-Zn CR, or CR plus sufficient exogenous zinc fortificant (Lo-Zn CR+Zn) matching the zinc content of Hi-Zn BfR.

Why It Was Studied

This study compared TAZ in a polished zinc-biofortified rice (Hi-Zn BfR) compared with Lo-Zn CR.

Who Took Part

The abstract describes 47 children taking part.

By PubMed's age tags, the people studied were young children, both men and women.

A total of 47 children 36-59-mo-old were enrolled in a crossover study.

On the day 1, children received a Lo-Zn CR diet.

How the Study Was Run

The design is described as crossover.

In the crossover set-up each of the children took both Vitamin D, K2, Magnesium and Zinc and the comparison in turn, acting as their own control.

Fractional zinc absorption (FZA) was measured in all diet periods using a triple-isotope tracer (oral 67-Zn and 70-Zn; intravenous 68-Zn) ratio technique; TAZ was calculated as product of zinc intake [total dietary zinc (TDZ)] and FZA.

What Was Measured

PubMed files the paper under topics including Bangladesh, Diet, Food, Fortified, Intestinal Absorption, Oryza and Zinc.

The authors tagged it with the keywords children, high-zinc rice and zinc-biofortified rice.
