01 / DESIGN
What was studied?
Intestinal segments from aged rats were studied for glucose and glycine transport after experimental exposure to two peptides.
02 / FINDINGS
What did the researchers report?
Transport responses differed by intestinal region, nutrient and peptide rather than changing uniformly throughout the gut.
03 / LIMITS
How should it be interpreted?
An isolated transport assay does not establish improved nutrition or healthy aging in people. Regional differences prevent a general absorption-enhancement claim.
