Chewing Hard Objects Boosts Brain GSH Levels and Improves Cognition?
2025-03-03
A Korean study found that chewing hard objects (like wooden blocks) significantly increases glutathione (GSH) levels in the anterior cingulate cortex of the brain. GSH is a crucial antioxidant, and higher levels are associated with better memory performance. In contrast, chewing gum showed no significant effect on GSH levels. Researchers suggest that increased cerebral blood flow from chewing hard objects may stimulate GSH synthesis. This study proposes a simple way to boost brain antioxidant defenses, but further research is needed to validate its effectiveness across different age groups and brain regions.
