) was injected subcutaneously 1 min before the emptying of glucose, fructose or agave at their 50% concentrations. When compared with saline emptying, gastric emptying of glucose was significantly delayed at its 25% and 50% concentrations, but the emptying of 12.5% glucose was not different from that of saline. Agave emptying, which was delayed with respect to saline emptying, was not altered by CCK-1 receptor blockade; but agave emptied from the stomach as rapidly as saline following the blockade of either CCK-2 or GLP-1 receptors. The findings demonstrate that the inhibitory effect of agave on gastric emptying is mediated by both CCK-2 and GLP-1 receptors, suggesting that natural sweeteners including agave may have satiating effects through the inhibition of gastric motility via enteroendocrine mechanisms.
