High- versus low-meat diets: effects on zinc absorption, iron status, and calcium, copper, iron, magnesium, manganese, nitrogen, phosphorus, and zinc balance in postmenopausal women.

What Was Tested

The paper reports a study of Zinc, published as a randomized controlled trial.

The effects of three diets--high meat (HM), low meat (LM), or low meat with mineral supplements (LS)--on zinc absorption, elemental balance, and related clinical indexes were investigated in a metabolic study of 14 women aged 51-70 y.

Lean beef, chicken, ham, and tuna in the HM diet replaced foods with a low mineral content in the LM diet.

Who Took Part

According to the abstract, 14 women were involved.

The age groups tagged for this paper are middle-aged adults and older adults, women only.

How the Study Was Run

In design terms this was a randomized 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.

What Was Measured

PubMed files the paper under topics including Absorption, Calcium, Diet, Energy Metabolism, Iron, Meat and Minerals.

What This Means in Plain Language

The paper is a randomized study of Zinc in 14 women.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 1995 (The American journal of clinical nutrition), a journal based in United States.
