Water consumption is essential to maintain hydration and good health. Sodium-bicarbonated mineral waters are reported to have beneficial digestive and hypocholesterolemic properties. The aim of this study was to investigate the effects of the consumption of a sodium-bicarbonated mineral water (BW) with or without a meal, compared to a low mineral content water as a control water (CW), on postprandial serum triacylglycerols (TAG), cholecystokinin (CCK), and gallbladder volume.
