Abstract

Purpose: To examine whether calcium type and co-ingestion with protein alters gut hormone availability. Methods: Healthy adults aged 26±7 years (mean±SD) completed three randomized, double-blind, crossover studies. In all studies, arterialized blood was sampled postprandially over 120-min to determine GLP-1, GIP and PYY responses, alongside appetite ratings, energy expenditure and blood pressure. In study one (n=20), three treatments matched for total calcium content (1058 mg) were compared: calcium citrate (CALCITR); milk minerals rich in calcium (MILK MINERALS); and milk minerals rich in calcium plus co-ingestion of 50 g whey protein hydrolysate (MILK MINERALS+PROTEIN). In study two (n=6), 50 g whey protein hydrolysate (PROTEIN) was compared to MILK MINERALS+PROTEIN. In study three (n=6), MILK MINERALS was compared to the vehicle of ingestion (water plus sucralose; CONTROL). Results: MILK MINERALS+PROTEIN increased GLP-1 incremental area under the curve (iAUC) by ~9-fold (43.7±11.1 pmol·L-1·120 min; p<0.001) versus both CALCITR and MILK MINERALS, with no difference detected between CALCITR (6.6±3.7 pmol·L-1·120 min) and MILK MINERALS (5.3±3.5 pmol·L-1·120 min; p>0.999). MILK MINERALS+PROTEIN produced a GLP-1 iAUC ~25% greater than PROTEIN (p=0.024; mean difference: 9.1±6.9 pmol·L-1·120 min), whereas the difference between MILK MINERALS versus CONTROL was small and non-significant (p=0.098; mean difference: 4.2±5.1 pmol·L-1·120 min). Conclusions: When ingested alone, milk minerals rich in calcium do not increase GLP-1 secretion compared to calcium citrate. Co-ingesting high-dose whey protein hydrolysate with milk minerals rich in calcium increases postprandial GLP-1 concentrations to some of the highest physiological levels ever reported.
