[리얼푸드=육성연 기자] “Chew and chew once more.”
It is a word emphasized in nutrition or medicine. Of course, food, not people, is the target.
Even though the ‘masticatory movement’ of chewing food prolongs the meal time, there are quite a number of benefits that can be obtained through this. From disease prevention to aging and obesity prevention, scientific research continues to prove the effectiveness of masticatory exercise.
“Effect on blood sugar… Helps prevent type 2 diabetes
If you chew your food well, it will digest better. This is because the more you chew, the more saliva comes out. According to medical experts, saliva contains not only natural digestive enzymes, but also immune substances and toxins removal substances.
Recently, a study has been published that suggests that masticatory exercise has an association with diabetes prevention. According to Turkiye’s thesis published in the latest issue of PLOS One, an international academic journal, it was confirmed that masticatory exercise has a positive effect on blood sugar levels in patients with type 2 diabetes. As a result of conducting a study on the relationship between masticatory movements and blood sugar, the blood glucose level of the group with the best masticatory movements due to good dental occlusion was the lowest compared to the other groups. The research team said, “Masticatory exercise helps to absorb nutrients such as dietary fiber, calcium, and magnesium, which are good for preventing diabetes.”
Brain stimulation→improvement of cognitive function
Chewing also stimulates the brain. It is reported that the act of chewing increases blood flow to the brain and activates brain functions as brain neurotransmitters are promoted. According to a paper published by Chonnam National University Hospital and Nara Medical University in Japan in 2013, those with poor dental health and low number of teeth had a 1.7-fold increased risk of dementia. In 2021, in a joint study of Karolinska Medical University Dentistry and Aging Research Institute, an elderly person who cannot chew food well appears to be significantly more likely to develop dementia compared to an elderly person who has no problems with copyright. It is an analysis that masticatory exercise increases nerve activity in the hippocampus, which is responsible for cognition and memory, and appears as an effect of learning, memory formation, and dementia prevention. In other words, just as we exercise our muscles at the gym, ‘chewing’ is a way to exercise the brain.
Kang Ji-won, executive representative of the Whole Grain Natural Eating Movement Headquarters, said, “If you masticate well through foods that can be chewed for a long time, such as whole grains, blood flow to the brain increases and the hippocampus is stimulated through periodontal vibration to activate memory and concentration.”
Aging delay and obesity prevention “Evenly developed facial muscles”
Mastication exercise is also a good exercise for a face that does not age quickly and for delaying aging. Jeong Chan-woo, director of JF Dermatology Clinic, emphasized masticatory exercise as a simple method that is good for delaying aging in his book ‘Making a Heart Line Face with Chewing Gum’. Citing a 2014 Dankook University Dentistry thesis, he explained, “Through masticatory exercise, facial muscles can be developed evenly and a three-dimensional sense of volume can be given.”
Overeating is also prevented. In order for us to feel full, the appetite suppressing hormone leptin must come out well, and this leptin secretion is secreted at least 15 minutes following the start of a meal. The longer the meal time is delayed through the chewing exercise, the better it is for the formation of a feeling of fullness.
