Utjecaj žvakanja žvakaće gume bez šećera nakon obroka zobene kaše na postprandijalnu glikemiju – cross-over istraživanje

Aim Chewing gums after a meal stimulates salivation and may affect the motility of the gastrointestinal tract and the release of hormones through neural mechanisms. This study was conducted in order to assess if chewing a sugar- free gum for 20 min following a meal, as recommended for dental caries prevention, influences the postprandial blood glucose levels in a period of one hour. Subjects and methods The study was conducted as a randomized cross-over trial. For each of 18 participants blood glucose profile was made by measuring capillary glucose concentration in 10-min intervals within one hour following a) chewing a sugar-free gum, b) the consumption of oatmeal, c) chewing a sugar-free gum after the consumption of oatmeal. One-way ANOVA with the Sidak post-hoc test was used to compare the glucose concentrations for the chewing gum group, the oatmeal group and the oatmeal+chewing gum group at each time point within a period of one hour. Results No statistically significant differences were found in the glycaemic response following complex carbohydrate ingestion when gum was chewed after a meal. Conclusion The possible influence of gum chewing on gastrointestinal and metabolic ongoings following a meal rich in complex carbohydrates was not reflected in the postprandial glycaemic response under the conditions of this study. Further studies exploring possible effects of gum chewing on the metabolic adaptability to nutritional challenges should include more variables related to vagal efferent activity, digestion and metabolism in order to gain a more complete view on these processes.
