Chewing harder foods, like wooden sticks, could boost brain glutathione levels and enhance memory, according to a research from South Korea. Scientists at Kyungpook National University found that chewing on harder materials for just five minutes increases glutathione (GSH), the brain's natural antioxidant, which helps protect against cognitive decline.
The study, published in rontiers in Systems Neuroscience, suggests that vigorous chewing could boost antioxidants and improve brain function. Glutathione defends against oxidative stress, which contributes to conditions like Alzheimer's, reports Hindustan Times.
As we age, GSH levels decline, making the brain more vulnerable to damage. This research shows that chewing harder foods can elevate GSH levels, possibly offering a natural way to support brain health.
In a study with 52 students, one group chewed soft paraffin wax gum, while the other chewed wooden sticks. Brain scans revealed that chewing on wood increased GSH levels significantly, particularly in the anterior cingulate cortex, which is crucial for memory.
Notably, this group also performed better on cognitive tests, suggesting that harder chewing may improve memory retention.
While chewing on wooden sticks may not be practical, incorporating crunchy foods like vegetables, nuts, or fibrous proteins could provide similar benefits. This simple method offers a potential non-drug way to enhance brain health, making it an easy and natural way to support cognition.
