Temporal Patterns of Glucagon and Its Relationships with Glucose and Insulin following Ingestion of Different Classes of Macronutrients

What Was Tested

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

The researchers aimed to investigate the associations between plasma glucagon, glucose, and insulin after ingestion of single macronutrients or mixed-meal.

Why It Was Studied

Glucagon secretion and inhibition should be mainly determined by glucose and insulin levels, but the relative relevance of each factor is not clarified, especially following ingestion of different macronutrients.

Who Took Part

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

Thirty-six participants underwent four metabolic tests, based on administration of glucose, protein, fat, or mixed-meal.

The researchers analyzed relationships between time samples of glucagon, glucose, and insulin in each individual, as well as between suprabasal area-under-the-curve of the same variables (ΔAUCGLUCA, ΔAUCGLU, ΔAUCINS) over the whole participants' cohort.

How the Study Was Run

The design is described as randomized and crossover.

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

In the crossover set-up each of the participants took both Glucagon and the comparison in turn, acting as their own control.

Glucagon, glucose, insulin, and C-peptide were measured at fasting and for 300 min following food ingestion.

What Was Measured

Glucagon secretion and inhibition should be mainly determined by glucose and insulin levels, but the relative relevance of each factor is not clarified, especially following ingestion of different macronutrients.
