| pubmed-article:8578189 | pubmed:abstractText | After nutrient ingestion there is an early response of glucagon-like peptide 1 (GLP-1) immunoreactivity, although GLP-1 is mainly produced in endocrine cells from the lower gut (ileum and colon/rectum), suggesting that indirect stimulation is important after the ingestion of carbohydrates that are predominantly absorbed from the upper intestine. | lld:pubmed |
