ABSTRACT
Background: Milk products deviate from other carbohydratecontaining
foods in that they produce high insulin responses, despite
their low GI. The insulinotropic mechanism of milk has not been
elucidated.
Objective: The objective was to evaluate the effect of common
dietary sources of animal or vegetable proteins on concentrations of
postprandial blood glucose, insulin, amino acids, and incretin hormones
[glucose-dependent insulinotropic polypeptide (GIP) and
glucagon-like peptide 1] in healthy subjects.
Design: Twelve healthy volunteers were served test meals consisting
of reconstituted milk, cheese, whey, cod, and wheat gluten with
equivalent amounts of lactose. An equicarbohydrate load of whitewheat
bread was used as a reference meal.
Results: A correlation was found between postprandial insulin responses
and early increments in plasma amino acids; the strongest
correlations were seen for leucine, valine, lysine, and isoleucine. A
correlation was also obtained between responses of insulin and GIP
concentrations. Reconstituted milk powder and whey had substantially
lower postprandial glucose areas under the curve (AUCs) than
did the bread reference (62% and 57%, respectively). Whey
meal was accompanied by higher AUCs for insulin (90%) and GIP
(54%).
Conclusions: It can be concluded that food proteins differ in their
capacity to stimulate insulin release, possibly by differently affecting
the early release of incretin hormones and insulinotropic amino
acids. Milk proteins have insulinotropic properties; the whey fraction
contains the predominating insulin secretagogue. AmJ Clin
Nutr 2004;80:1246 –53.
