What are the benefits of chewing in preventing Alzheimer’s disease?

　　Japanese researchers have found that chewing can prevent Alzheimer's disease.

　　New short-term memories are stored in a cell area called the "hippocampus" that is closely related to the brain and is responsible for memory. As people age, the "hippocampus" cells begin to degenerate, resulting in a decrease in short-term memory. Some studies believe that tooth loss may be related to the degeneration of "hippocampus" cells.

　　Researchers used magnetic resonance technology to film the activity in people's brains as they chewed. They found that when people chew, the number of hippocampal cells in the brain increases significantly. But the mystery is why chewing irritates the brain.

　　An expert from the Center for Molecular Medicine at the University of Edinburgh said that when people chew, it sends signals to hippocampal cells, thereby reducing levels of stress hormones in the blood. if elderly By chewing less, stress levels in their bodies rise, turning short-term memory loss into dementia.

　　The chewing function is interconnected with the brain center. When chewing, the jaw joint moves to smooth the brain circulation and strengthen the activation of the cerebral cortex, thereby preventing brain aging and Alzheimer's disease. Therefore, the elderly who have lost teeth should be fitted with dentures as soon as possible to restore chewing function.
