An investigation of the role of oro-sensory stimulation in sugar satiety?
OBJECTIVE
To investigate whether oral factors stimulated by the presence of sucrose in the mouth are involved in the suppression of appetite following sucrose ingestion.


METHODS
Ten male and 10 female healthy volunteers participated in four experimental conditions designed to provide differing levels of oro-sensory stimulation. Appetite and energy intake from a test meal were measured after subjects chewed and ingested sucrose-containing pastilles over a 10 min period, consumed a sucrose-containing jelly over a 5 min period, consumed a sucrose-containing drink within 2 min and drank plain water within 2 min. The three sucrose-containing preloads were similar in nutrient composition, each containing 251 kJ.


RESULTS
Ratings of hunger and fullness did not differ between the four conditions following ingestion of the preloads. However, energy intake from a test lunch was significantly reduced after consuming the pastilles when compared with the plain water and equicaloric sweet drink conditions.


CONCLUSIONS
These results suggest that enhanced oro-sensory stimulation from chewing the sweet food was involved in the suppression of food intake.
