Food plays an important role in human life. And it’s not just about saturated with beneficial trace elements or vitamins, but also about memory, learning and stress.
Doctor Andrew Blueskin notes that the so-called soft, chopped foods (soft diet) can lead to poor working memory.
It can also reduce neurogenesis in the hippocampus (part of brain) and increases the risk of neurodegenerative disorders.
The hippocampus is one of the few parts of the brain capable of producing new neurons. This process is called neurogenesis. It increases the openness of networking for the new doctrine. The hippocampus is also responsible for spatial orientation, involved in the control of emotions.
Excess soft food reduces stress resistance of a person and affects the health of teeth.
Recent studies suggest that chewing during stress reduces the activity of the stress axis and the cognitive deficit induced by stress damage the hippocampus.
Chewing is also good for cerebral blood flow, and MRI studies show that it affects the function of the cerebellum, which is associated with the control of rhythmic locomotor activity. The process of chewing reduces the rate of release of noradrenaline in the amygdala and ACTH (the hormone responsible for activity of the adrenal glands) and stress hormone cortisol.
The doctor notes that the removal of teeth in animals leads to impaired memory problems in learning. But after their recovery, improve cognitive function, even in older animals. Chewing is useful not only for animals but also for humans. An excess of stress in humans is often bruxism – teeth grinding during sleep, which increases the risk of tooth decay and other problems.
The more chewing, the more reduced levels of cortisol and adrenaline. Fast chewing reduces cortisol levels by 26% in 20 minutes.
