The project aims to precisely quantify the postprandial amino acid utilization of egg proteins in vivo in humans, and also to assess their satiating power, in relation with nutrient postprandial waves and incretin secretions. For that purpose, 2 independent studies are conducted. The first one is realized using stable isotopes on 8 volunteers ingesting an egg test meal. The second one is a cross over design performed on 30 volunteers to compare the satiating effect of 2 equivalent snacks: whole eggs or cottage cheese.

Condition Intervention
Dietary Supplement: Egg snack
Dietary Supplement: Cottage cheese

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Primary Purpose: Basic Science

Further study details as provided by Institut National de la Recherche Agronomique:

Primary Outcome Measures:
  • energy intake at lunch following the snack
  • Dietary amino acid utilization
    transfer of stables isotopes used as intrinsic markers of egg proteins to metabolic pools

Secondary Outcome Measures:
  • plasma incretin concentrations
    insulin, glucagon, GLP-1, PYY, ghrelin, GIP

  • postprandial nutrient waves
    plasma glucose, cholesterol, triglyceride, urea

  • neoglucogenesis
    Endogenous production of glucose and contribution of dietary amino acids
