However, in recent years the field of sweet taste has experienced a sudden twist due to the presence of taste receptors (TR) not only in clusters in the oral cavity (taste buds) but also in non-taste tissues particularly in the mucosa of the GIT. It is believed that the TR expression in the GIT mucosa is related to post-ingestive events such as the recognition of nutrients in the lumen (i.e. glucose) and the facilitation of digestion and absorption (Dyer et al. 2005, Mace et al. 2009). Furthermore, TR in enteroendocrine cells may participate in the complex events leading to control of feed intake. For example, dietary carbohydrates and some HIS may increase glucose absorption by stimulating the T1R2 receptor in the gut mucosa which, in turn, triggers active glucose transport through the SGLT1. Porcine sweet TRs have been involved in up-regulating SGLT1 and glucose uptake after stimulation with sucrose, SAC or NHDC in piglet intestinal mucosa (Figures 1 and 2 –Moran et al. 2010-). If these findings would be confirmed we could speculate in HIS to be involved in improving glucose uptake but also to initiate an orexigenic response through GLP1, thus potentially enhancing feed intake in piglets through post-ingestive events.
