Chewing is an action that usually happens without much conscious thought. However, it is a complex system that is constantly redesigning how you chew. Muscle memory is a concept that is often discussed in sports, where practice instills a certain pattern into your muscle memory, allowing you to reproduce those patterns without thinking about them. This is also true for chewing, as your jaw muscles learn and adapt to the way you bite, and reinforce the proper motions to break down food. Research has also shown that chewing is important for preserving and promoting general health, including cognitive functions in the hippocampus, a region vital for spatial memory and learning.

What You'll Learn
Chewing is a form of muscle memory
Chewing is a complex action that often happens without much conscious thought. We tend not to notice how we chew or how our teeth are contacting. However, a system is at work that is constantly redesigning how we chew. This system is muscle memory, a concept that many will be familiar with from sports, where practice instills a certain pattern that can be reproduced without conscious thought.
The muscles of mastication are a group of muscles responsible for the chewing movement of the mandible at the temporomandibular (TMJ) joint. They enhance the process of eating and assist in grinding food. The four main muscles of mastication originate from the surface of the skull and attach onto the rami of the mandible at the TMJ. The movement performed by these muscles are elevation, depression, protrusion, retraction, and side-to-side movement.
The jaw muscles learn and adapt to the way that we bite. However, this can sometimes cause negative effects, such as excessive stress on the jaw joint or muscles. This can lead to TMJ symptoms such as headaches. The habitual bite learned may also put excessive force on a few teeth, resulting in wear or damage.
Chewing is important not only for food intake but also for preserving and promoting general health. Recent studies have shown that mastication helps maintain cognitive functions in the hippocampus, a central nervous system region vital for spatial memory and learning. Animal and human studies have indicated that cognitive functioning is influenced by mastication. Chewing has also been shown to increase cerebral blood flow, which may decrease the risk of cognitive impairments.

Chewing and its impact on memory and learning
Chewing is an action that usually occurs without much conscious thought. However, it is a complex system that is constantly redesigning how you chew. This is where muscle memory comes into play. Muscle memory is a concept that is often discussed in sports, where practice instills a certain pattern into your muscle memory, allowing you to reproduce those patterns without thinking about them consciously. This is also how you learn to chew properly. Your jaw muscles learn and adapt to the way you bite, but sometimes this can cause negative effects, such as excessive stress on your jaw joint or certain teeth.
Chewing is not only important for food intake and digestion but also for maintaining general health and cognitive functions. Recent studies have shown that mastication helps preserve cognitive functions in the hippocampus, a region of the brain that is vital for spatial memory and learning. Animal and human studies have indicated that cognitive functioning is influenced by mastication, and masticatory dysfunction is associated with hippocampal impairments and spatial memory deficits, especially in the elderly.
The forces created when you chew play a role in how your body works. Chewing, ripping, tearing, and swallowing stimulate your face and throat muscles and help develop optimal anatomy and function of your jaws, vocal cords, and even your brain. Chewing helps preserve the hippocampus, which deals with memory and other cognitive functions, by increasing blood flow to your brain. Chewing has also been long researched as a stress-reducing behavior, which can further positively impact cognitive abilities.
Additionally, the type of food you eat can impact how much you chew. For example, crunchy and chewy foods like jerky, cheese, dried apricots, or granola require more chewing than softer foods. By choosing foods that require more chewing, you can exercise your head and neck muscles, which may have additional benefits for your cognitive function and protection against neurodegenerative diseases.

Chewing and its influence on hippocampal function
Chewing is an action that typically occurs without much conscious thought. It is a complex system that is constantly redesigning the way we bite and chew. Our jaw muscles learn and adapt to the way we bite, but this can sometimes cause negative effects, such as excessive stress on the jaw joint or certain teeth.
Mastication (chewing) is important not only for food intake but also for preserving and promoting general health. Recent studies have shown that mastication helps maintain cognitive functions in the hippocampus, a region of the central nervous system vital for spatial memory and learning. There are multiple neural circuits connecting the masticatory organs and the hippocampus. Animal and human studies have indicated that cognitive functioning is influenced by mastication, with masticatory dysfunction associated with hippocampal morphological impairments and hippocampus-dependent spatial memory deficits, especially in the elderly.
Several studies have suggested that chewing during a stressful event can rescue stress-impaired hippocampal functions. Restraint stress induces the expression of corticotrophin-releasing hormone in the paraventricular nucleus of the rat hypothalamus, whereas chewing during restraint stress significantly suppresses the stress-induced enhancement of this hormone. Chewing also alters hypothalamic-pituitary-adrenal axis function and improves the ability to cope with stress in rodents. Given that stress negatively influences hippocampus-dependent learning and memory, these studies suggest that masticatory movements improve the stress-induced impairment of spatial memory in conjunction with increased hippocampal glucocorticoid receptor expression.
Chewing has also been found to positively influence cerebral blood flow, which may be one reason why it enhances cognitive ability. Chewing, ripping, tearing, and swallowing also stimulate the muscles in the face and throat and help develop optimal anatomy and function of the jaws, vocal cords, and even the brain.

Chewing and its effect on stress reduction
Chewing is an action that usually occurs without much conscious thought. However, it involves a complex system that constantly redesigns the way we chew. This system is known as muscle memory, which allows us to reproduce certain patterns without consciously thinking about them.
The forces created when we chew play a role in how our body works. Chewing, ripping, tearing, and swallowing stimulate our face and throat muscles, helping develop optimal anatomy and function of our jaws, vocal cords, and even our brain. Research has shown that the act of chewing helps preserve the hippocampus, a part of the brain that deals with memory and other cognitive functions, by increasing blood flow to the brain.
Chewing has been studied as a potential stress-reducing behavior, and research has indicated a link between chewing and lower stress levels. For example, a study found that participants who chewed gum reported lower levels of depression, anxiety, and stress, while also achieving higher academic success scores. Another study found that chewing gum four times a day post-operatively reduced perceived pain in patients undergoing routine colorectal surgery.
The neural mechanisms underlying the stress-reducing effects of chewing involve the prefrontal cortex, which then changes the HPA axis and ANS activity. Additionally, the act of chewing may affect stress through neurotransmission effects, particularly those related to serotonin, a neurotransmitter that influences mood and anxiety.
While the exact mechanisms remain unconfirmed, the available research suggests that chewing can be a simple and cost-effective method for reducing stress and improving overall cognitive function.

The jaw muscles learn and adapt to the way we bite. However, sometimes this can lead to negative effects, such as excessive stress on the jaw joint or specific teeth, resulting in TMJ symptoms like headaches. This can be addressed through tools such as the Tekscan system, which helps determine the distribution of forces in the mouth during biting.
Chewing is important not only for food intake but also for preserving and promoting general health. Recent studies have shown that mastication helps maintain cognitive functions in the hippocampus, a region vital for spatial memory and learning. Animal and human studies indicate that cognitive functioning is influenced by mastication, with masticatory dysfunction associated with hippocampal impairments and memory deficits, particularly in the elderly. Chewing has also been linked to increased cerebral blood flow, which may enhance cognitive ability and reduce the risk of cognitive impairments.
