Postprandial amino acid response after the ingestion of pea protein, milk protein, casein and a casein–pea blend, in healthy older adults

The effect of food composition, processing, and texture on intragastric behavior, gastric emptying, and postprandial nutrient absorption

“…2001) used T2 relaxation time to monitor the process of dilution by gastric secretions and mixing of viscous meals and Goetze et al (2009) used fast T1 mapping techniques for the quantification of intra-gastric dilution and distribution of orally applied gadolinium-based paramagnetic contrast agents showing that there is potential for estimating gastric secretion volumes with MRI.Intra-and interindividual variability is not only present in gastric fluid secretion, but also in gastric emptying, transit times, and nutrient absorption and should be taken into consideration. For example, the study ofvan Dam et al (2023) shows that there is large inter-individual variation in plasma amino acid concentrations after consumption of different protein drinks. Some individuals only have a slight increase in amino acid concentrations, while others show a substantial increase in response to the same drink.…”
