The L-cells in the intestinal epithelium express various nutrient-sensing receptors: Dietary fats are particularly potent GLP-1 secretagogues, activating free fatty acid receptors (such as GPR40 and GPR120) on L-cells Proteins and amino acids stimulate GLP-1 through peptide-sensing mechanisms and calcium-sensing receptors Carbohydrates trigger release via glucose transporters and sweet taste receptors expressed on enteroendocrine cells Dietary fibre , particularly soluble fibre, promotes GLP-1 secretion through fermentation products (short-chain fatty acids) produced by gut microbiota The rate and site of nutrient delivery also influences GLP-1 response
Curcumin Curcumin (a compound found in the spice turmeric) is thought to help the body combat many infections, including those caused by viruses, due in part to its anti-inflammatory and antioxidant properties
