Effect of Ingestion of Human, Cow, and Modified-cow Milk, on Glucose and Hormone Responses in Humans. — PROLAT  

Insulin Tolerance Clinical Trial

Official title: Study of the Effects of Ingestion of Natural Human, Natural Cow, and Modified-cow Milk, on Glucose, Amino Acids, Insulin, and Incretin Responses in Humans

Status Completed

Clinical Trial Summary

Human milk, despite a much lower protein content, is as effective as cow milk on insulin stimulation under iso-lactose conditions. The causes for such a similar potency are unknown. This effect could be due to incretin and amino-acid responses, and/or to milk-protein interactions.In this study the investigators will address the above question(s) by testing, in young healthy volunteers, the effects of natural cow and human milk, as well as of the manipulation of the casein and whey protein content in cow milk, on insulin, C-peptide, GLP-1 and GIP secretion, as well as on circulating amino acids.

Clinical Trial Description

Objective: To determine plasma glucose, insulin, C-peptide, glucagon-like polypeptide-1 (GLP-1), glucose-inhibitory-polypeptide (GIP) and amino-acid responses, following administration of human and cow milk, either natural or with experimentally-modified casein and whey-protein content(s). Design. Young healthy volunteers of both sexes will receive iso-lactose loads (0.36 g lactose / kg body weight) of: natural cow milk; natural human milk; and of cow milk with modified casein and whey protein contents. Blood samples will be frequently collected over 4 hours. Plasma glucose, amino acids, insulin and incretin concentrations will be measured. ;
