A controversial idea that is gaining support
A long time ago, American nutrition advocate Horace Fletcher became famous for his extreme chewing habit. He claimed food should be chewed until it turns almost liquid. He even believed this could reduce food intake and save money at a large scale in society.
His methods were unusual, but modern researchers say he was not entirely wrong.
How chewing affects the brain
Experts now suggest that chewing more than usual may do more than help digestion. It can also support brain function. Studies indicate that stronger chewing activity increases blood flow to the brain, which may improve attention, focus, and memory performance.
Researchers also link good oral health with lower risks of cognitive decline. Some studies suggest a connection between tooth loss, gum disease, and conditions like dementia and Alzheimer’s disease. While chewing is not a treatment, it may play a supporting role in keeping the brain active.
The science behind mastication
Chewing is not just a mechanical step in eating. It activates muscles in the jaw that increase blood circulation and stimulate parts of the nervous system. According to scientists studying human evolution, our jaws and teeth have changed over millions of years, which may also influence how we process food and energy today.
