A dog chewing a stick may be in something. We don’t necessarily have to be fangs, but the basic concept is hard and durable. It is worth considering.
A new study shows that chewing hard materials such as wood can increase the level of antioxidants that occur naturally in the human brain, which can improve human memory.
Many of course chewing gum. Of course, it’s softer, but it’s more delicious than a tree (and avoids tongue fragments). Previous research was actually chewing gum. Increase Brain activityAs an author of new research.
Getting blood supply pumping in the brain seems to improve a variety of cognitive functions. Interestingly, clinical evidence also suggests that people who chew the challenges tend to have lower cognitive function and higher mental disorders.
However, it is not clear what certain metabolic changes related to the improvement of the brain blood flow can cause certain metabolic changes.
In a new study, the researchers have investigated one possible explanation related to oxidation stress in neuropathic tissues, which have already played a pivotal role in the decline of cognitive function.
Some metabolic processes can produce harmful molecules known as reactive oxygen species, causing cumulative oxidation damage in the human brain. One of the best defenses of the brain for oxidation stress is an antioxidant called glutation (GSH), which has many important things throughout the body, including protecting neurons from reactive oxygen species.
Hope to reveal the cognitive effects of chewing, researchers designed new research to explore the potential role of glutathione. They pointed out that despite the importance of the brain, the relationship between glutation level and work has not attracted much attention.
They recruited 52 healthy college students from DAEGU and divided them into two groups. One of the 27 subjects chewed the paraffin wax gum. The second group of 25 was asked to chew on wooden medical tongue depression.
Subjects chewed for five minutes, and the researchers used magnetic resonance spectroscopy to measure glutathione levels in the anterior Singant cortex, a brain area for cognitive control before and after chewing. All subjects also conducted a cognitive test before and after activity.
Researchers reported that the glutathione levels were significantly higher in the target, especially in wood chewing groups, especially when compared to the gum chewing group.
In combination with the results of cognitive tests, the increase in glutathione concentration was positively correlated with memory function. In other words, people with chewing trees and having larger glutathion boosts also performed better in the test.
“As far as we know, this is the first report that shows that the work can change the level of antioxidant in the human brain and the increase in the level of brain oxidizer is associated with cognitive function.” write.
The authors of the research added that more research will be needed to back up these results, adding to the larger sample size, wider demographic statistics and evaluation of various brain areas.
Wood seemed to give more benefits than paraffin wax gum, but this study also tested only two materials chewing for 5 minutes. Future studies can also investigate the wider range of materials and chewing duration.
These results alone may not be enough evidence to chew wood for better memories, but it offers a powerful hint. And if the chewing tree has this effect, it will be good news. Researchers wrote in consideration of the challenge of managing glutation levels in the brain.
“There are no drugs or established practices to increase the current brain GSH level, so our research results show that moderately hard materials can play an effective role in raising the GSH level of the brain.” write.
