Adaptation in human zinc absorption as influenced by dietary zinc and bioavailability.

What Was Tested

Researchers studied Zinc in this randomized controlled trial publication.

The researchers aimed to assess adaptation in human zinc absorption to controlled differences in zinc and phytate intakes and to apply the results to predictive models.

In 3 experiments, radiotracers were used to assess zinc absorption by healthy adults (n = 109) from controlled diets, before and after 4 or 8 wk of dietary equilibration.

Why It Was Studied

An understanding of the relations among dietary zinc intake, bioavailability, and absorption is necessary for making dietary intake recommendations.

Who Took Part

PubMed indexes the participants as adults and middle-aged adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized and crossover study.

Because people in this Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Each person switched between Zinc and the comparison at some point, usually with a gap in between.

What Was Measured

PubMed files the paper under topics including Adaptation, Physiological, Biological Availability, Body Mass Index, Diet, Intestinal Absorption, Nutritional Status and Phytic Acid.

What This Means in Plain Language

The paper is a randomized and crossover study of Zinc.

Its findings take up roughly 7 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2008 (The American journal of clinical nutrition), a journal based in United States.
