Summary

The main goal of this study is to determine the difference in amino acid digestibility of milk, sorghum and black beans between older (65-80 years) and younger (20-35 years) adults using the dual tracer method.

Interventions

OTHER

Milk

Twenty grams of the deuterium (2H) - labelled skimmed milk powder mixed with water will be consumed on one of the three different test days. The meal will be divided in 10 portions, consumed every hour. The 2H-labelled protein source is mixed with free 13C-labelled amino acids as reference. Protein free cookies are served alongside to equal macronutrient composition with the other two protein sources.

OTHER

Sorghum

Twenty grams of the deuterium (2H) - labelled whole grain sorghum cooked with water will be consumed on one of the three different test days. The meal will be divided in 10 portions, consumed every hour. The 2H-labelled protein source is mixed with free 13C-labelled amino acids as reference.

OTHER

Black beans

Twenty grams of the deuterium (2H) - labelled black beans cooked with water and mashed into a puree, will be consumed on one of the three different test days. The meal will be divided in 10 portions, consumed every hour. The 2H-labelled protein source is mixed with free 13C-labelled amino acids as reference. A carbohydrate drink is served alongside to equal macronutrient composition with the other two protein sources.
