Zinc and iron utilization in young women consuming a beef-based diet.

What Was Tested

This randomized controlled trial looks at Zinc and Iron.

The purpose of this study was to determine the utilization of zinc in young adult women fed diets containing varying amounts of lean ground beef.

A secondary objective was to determine the utilization of iron.

Why It Was Studied

The 28-day study was divided into one 7-day preexperimental period, during which a vegetarian diet was fed, and three randomly arranged 7-day experimental periods.

During the experimental periods, the diets contained 3, 6, or 9 oz of beef, supplying varying levels of zinc and iron.

Who Took Part

By PubMed's age tags, the people studied were adults, women only.

How the Study Was Run

In design terms this was a randomized study.

The participants were allocated by chance, so the Zinc group and the comparison group should start out alike.

What Was Measured

During the experimental periods, the diets contained 3, 6, or 9 oz of beef, supplying varying levels of zinc and iron.
