Now the connections are starting to become clear thanks to new research such as Using your jaws sharpens your teeth... and mind! and
Skeletal Anterior Open Bite Attenuates the Chewing-Related Increase in Brain Blood Flow
When chewing, the muscles of the jaw and face need blood. The only blood vessel supplying the head is the carotid artery, which divides below the ear. One half goes to the chewing muscles while the other half supplies the brain with blood. Dementia is caused by nerve cells dying, and they do so if they don't get enough blood with oxygen and nutrients.
Needless to say, CHUMI is second to none when it comes to blood flow to the head. The increased blood flow associated with chewing may also explain chewing's well-documented positive effects on the brain. We dare to conclude that you not only use your jaw to sharpen your teeth, but also to sharpen your thoughts, write the researchers.
