Section 3-3. Efficacy of chewing gum

When we become sleepy while driving a car, we usually chew a chewing gum. In contrast, whenever becoming nervous, we sometimes chew a chewing gum to find relief. This is because we know from our previous experiences that chewing a gum is associated with brain stimulation, awaking or sedation. To be frank, a chewing gum effect can be recognized as an unconscious “Hazo effect”. Overall chewing with both front teeth and back teeth provides well-balanced homogeneous stimulation of both sympathetic and parasympathetic nerves, which is useful for taking balance of autonomic nervous systems. If you prefer to take a comfortable stimulation mainly, you are recommended to chew a gum with back teeth including the second bicuspid and backward teeth whereas if you wish to taka a stimulation of excitation systems for waking or elevating the blood pressure, it is better for you to chew a gum with canine teeth and the first bicuspid in the front area. Like these examples, teeth possess interesting potentials.It has recently been reported that chewing a gum improved metabolism ratio of us by 19% per hour and fat was consumed by additional 11 Kcal, resulting in inhibition of obesity. Although chewing actions seem only a local exercise associated with chewing muscles, it is the systemic exercise including stimulation of both blood flow of brain and cerebral functions, as stated above. As the natural consequence, continuous chewing of a chewing gum leads to activation of systemic metabolism and improvement of the metabolism ratio.
