What This Study Did, in Plain Language

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

To determine the second meal effects of calcium and vitamin D on postprandial glucose, insulin, non-esterified fatty acids (NEFA) and glycerol.

Who Took Part

By PubMed's age tags, the people studied were middle-aged adults, both men and women.

Eight volunteers aged (mean+/-s.e.m.) 55.5+/-1.2 years and body mass index 29.0+/-1.6 kg/m(2), completed a randomized within-subject design that compared a low calcium-low vitamin D breakfast and an isocaloric high calcium-high vitamin D breakfast (HCB).

How the Study Was Run

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

Because people in this Vitamin D, K2, Magnesium and 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 Vitamin D, K2, Magnesium and Zinc and the comparison at some point, usually with a gap in between.

Four hours following each breakfast, a very low calcium standard lunch was ingested.

Serial blood collections were made on the hour over a duration of 8 h.

Postprandial responses were calculated as the percentage change (Delta) from the fasting value for breakfast meals, and the 4th hour breakfast value for each lunch, respectively.

What Was Measured
