A comparison between the absorption for amino acid alone and amino acid plus xylose given simultaneously shows that in the presence of xylose a considerable delay occurred in the appearance of peak levels. The differences were statistically significant showing that D xylose inhibits amino acid absorption in a healthy human. Thus it is postulated that a large amount of carbohydrates in a Thai diet may suppress the absorption of amino acids by the intestinal epithelium.Mahidol UniversityMedicineArticleSCOPUS
