Smita Raithore, Devin G Peterson
The influence of polyol type and particle size on the flavor release profile of chewing gum was investigated in vivo. Four chewing gum samples with an average particle size of 62 or 246 μm for sorbitol and 57 or 184 μm for mannitol were analyzed. Chewing gum formulated with mannitol, in general, had a higher aroma release than chewing gum formulated with sorbitol. Polyol type did not influence the release profile of the high intensity sweeteners (HIS) aspartame and acesulfame K. However, a smaller particle size resulted in a significantly higher release of HIS...

M A R Buzalaf, A C Magalhães, D Rios
This article provides an overview of the nutritional and patient-related risk factors involved in the aetiology of erosive tooth wear (ETW) and the preventive strategies to counteract them. The first step is to diagnose clinical signs of ETW and to recognise causal factors. Low pH and high buffer capacity of foods/drinks are the major risk factors, while the calcium concentration is the main protective factor. Reduction of frequency of consumption and contact time of erosive foods/drinks with the teeth, use of straws appropriately positioned and consumption of dairy products are advisable...

Based on the theory of incentive sensitization, the exposure to food stimuli sensitizes the brain's reward circuits and enhances attentional bias toward food. Therefore, reducing attentional bias to food could possibly be beneficial in preventing impulsive eating. The importance of chewing has been increasingly implicated as one of the methods for reducing appetite, however, no studies to investigate the effect of chewing on attentional bias to food. In this study, we investigated whether chewing stimulation (i...

BACKGROUND: Postoperative ileus is a common complication of abdominal surgery, leading to patient discomfort, morbidity and prolonged postoperative length of hospital stay (LOS). Previous studies suggested that chewing gum stimulates bowel function after abdominal surgery, but were underpowered to evaluate its effect on LOS and did not include enhanced recovery after surgery (ERAS)-based perioperative care. This study evaluated whether chewing gum after elective abdominal surgery reduces LOS and time to bowel recovery in the setting of ERAS-based perioperative care...
