True Ileal Protein Digestibility of Zein and Whey Protein Isolate in Healthy Humans (OR27-06-19)

There are limited data available on true ileal nitrogen and amino acid digestibility of protein sources. The goal of this study was thus to determine for the first time in healthy volunteers the ileal digestibility of zein and whey proteins. Twenty-two volunteers (10 women and 12 men; aged 37 ± 12y) were equipped with a double lumen intestinal tube positioned at the ileal level. They received a single meal of protein-free biscuits and a drink...
