“…In the present study, the PD group showed a larger body weight than the SD group, a result consistent with some earlier reports [ 24 , 25 ]. Several mechanisms related to mastication are independently or synergistically involved in soft diet-induced obesity.…”

“…The soft-fed rats showed greater adiposity and attenuated postprandial thermogenesis than the hard-fed rats [ 24 ]. Hashimoto et al showed that powder diet resulted in an attenuated response to oral glucose tolerance test [ 25 ]. In addition, mastication activated the satiety center in the hypothalamus through histamine innervation [ 22 , 23 , 40 ].…”

“…For example, experiments with shorter interventional period, from 1 week to 4 months, result in no change in body weight [ 16 , 17 , 40 , 41 ]. On the contrary, Wistar King A rats that fed on soft diet showed larger body weight with decreased thermogenesis after 22 week olds [ 24 ], and Wistar rats that fed on powder diet were heavier at 45 week olds or older, which are ages when abnormal glucose metabolism became prominent [ 25 ]. Interestingly, some studies reported no difference in the amount of food intake between groups at any age [ 24 , 25 , 40 ].…”

“…Many studies have shown that a soft diet caused smaller mandibular, maxillary, and cranial skeleton compared to a standard diet in rodents [ 16 – 20 ] and monkey [ 21 ], supporting the observations in epidemiological studies. Although soft diet-induced obesity is an inconsistent phenotype, several mechanisms related to mastication such as activation of satiety [ 22 , 23 ], postprandial thermogenesis [ 24 ], and blood glucose metabolism [ 25 ], are suggested to be involved in this phenotype. It has been reported that a long-term soft diet or induced occlusal hypofunction causes poor performance on memory and learning tests [ 26 – 28 ].…”

Chronic Powder Diet After Weaning Induces Sleep, Behavioral, Neuroanatomical, and Neurophysiological Changes in Mice

The purpose of this study is to clarify the effects of chronic powder diet feeding on sleep patterns and other physiological/anatomical changes in mice. C57BL/6 male mice were divided into two groups from weaning: a group fed with solid food (SD) and a group fed with powder food (PD), and sleep and physiological and anatomical changes were compared between the groups. PD exhibited less cranial bone structure development and a significant weight gain. Furthermore, these PD mice showed reduced number of neurogenesis in the hippocampus. Sleep analysis showed that PD induced attenuated diurnal sleep/wake rhythm, characterized by increased sleep during active period and decreased sleep during rest period. With food deprivation (FD), PD showed less enhancement of wake/locomotor activity compared to SD, indicating reduced food-seeking behavior during FD. These results suggest that powder feeding in mice results in a cluster of detrimental symptoms caused by abnormal energy metabolism and anatomical/neurological changes.

“…19,20 Terdapat perbedaan signifikan pada kadar glukosa postprandial 15 menit antara kelompok mengunyah 22 kali dan 40 kali tiap suapan yang mendukung penelitian sebelumnya yang menggunakan model hewan coba dan subjek manusia menunjukkan bahwa peningkatan aktivitas mengunyah memudahkan absorpsi glukosa. [21][22][23][24] Mengunyah merupakan langkah pertama dalam proses pencernaan dan berfungsi dalam menyiapkan makanan untuk ditelan dan diproses lebih lanjut pada sistem pencernaan. Mengunyah akan memecah makanan menjadi ukuran yang lebih kecil, menstimulasi saliva, mencampur makanan dengan enzim, dan meningkatkan hidrolisis karbohidrat di mulut dan organ pencernaan serta meningkatkan respon glikemik dan insulinemik.…”

Background: Obesity cause various physiological changes in the body, one of which is insulin resistance causes high blood glucose levels. Chewing is a stimulus of cephalic phase responses and sensory stimulation that can increase hormones releasing such as insulin, ghrelin, cholecystokinin (CCK) and glucagon like peptide-1 (GLP-1). Chewing plays important role in determining postprandial plasma glucose concentration.Objective: Investigate the effect of chewing on postprandial blood glucose in obese adults.Method: This was true experimental research. Research subjects were treated in the form of chewing 22 times and 40 times each mouthful. Blood glucose levels were measured using glucometer on fasting blood glucose and postprandial blood glucose 15 minutes, 30 minutes, 60 minutes, and 120 minutes. Statistical test using Independent t-test.Results: The mean postprandial glucose levels in the 22 chews group at 15 minutes, 30 minutes, 60 minutes, and 120 minutes were 112.11 ± 14.3328, 126.11 ± 15.667, 116.94 ± 15.539, and 89.67 ± 11.668 . While the mean postprandial blood glucose levels in the 40 chews group at 15 minutes, 30 minutes, 60 minutes, and 120 minutes were 122.22 ± 14.381, 129.61 ± 15.112, 109.50 ± 14.995, and 85.83 ± 13.963. There were statistically significant differences between chewing groups 22 times and chewing 40 times on fasting blood glucose and 15 minutes postprandial blood glucose (p = 0.041 and p = 0.042), while on 30 minutes postprandial glucose testing, 60 minutes , and 120 minutes there was no significant difference (p> 0.05).Conclusion: There was significant differences in 15 minutes postprandial blood glucose level between group 22 times chewing and 40 times chewing each mouthful.
