Chewing process and benefits - Chewing is the process of crushing and grinding food with teeth. - It increases the surface area of food for efficient enzyme breakdown. - Muscles of mastication move the jaws to bring the teeth into intermittent contact. - Chewing makes the food softer and warmer, and saliva enzymes begin breaking down carbohydrates. - Increasing the number of chews per bite can increase relevant gut hormones. - Chewing may decrease self-reported hunger and food intake. - Chewing stimulates saliva production and increases sensory perception of food. - Chewing almonds 25-40 times keeps people fuller and allows for better nutrient absorption. - Chewing stimulates the hippocampus and is necessary for its normal function.

Chewing in animals - Chewing is mostly a mammalian adaptation, but some herbivorous dinosaurs also developed chewing. - Birds, amphibians, and living reptiles do not chew. - Cattle and other ruminants chew food more than once to extract more nutrients. - Some animals, like cows, chew for long periods in a process called rumination. - Chewing allowed ornithopod dinosaurs to obtain more nutrients from tough plant life.

Chewing motor program - Chewing is primarily an unconscious act, but can be mediated by higher conscious input. - The motor program for mastication creates and controls the complex patterns of chewing. - Feedback from teeth and temporomandibular joints govern the creation of neural pathways. - The motor program continuously adapts to changes in food type or occlusion. - Conscious mediation is important in limiting parafunctional habits and excessive engagement of the motor program.

Chewing in machinery - The process of chewing has been applied to machinery, such as forestry mulching machines. - A cold press juicer uses the mastication process to extract juice without loss of nutrients. - Chewing in machinery involves chewing through brush and timber for clearing firelines. - The U.S. Forest Service utilizes a machine called a masticator for this purpose. - Chewing in machinery reduces friction and allows for efficient extraction or clearing.

Chewing and its effects on appetite, nutrition, cognitive function, food transport, and dental health - Chewing affects appetite and food intake. - Chewing increases feelings of fullness and satisfaction. - Chewing reduces the amount of food consumed in a meal. - Chewing promotes mindful eating and slower eating pace. - Chewing influences the release of gut hormones that regulate hunger and satiety. - Impaired mastication negatively impacts nutrition. - Difficulties in chewing can lead to reduced food intake. - Impaired mastication affects the ability to properly break down food. - Insufficient mastication can result in inadequate nutrient absorption. - Impaired mastication may contribute to malnutrition. - Chewing maintains hippocampus-dependent cognitive function. - Chewing is associated with improved memory and learning. - Chewing stimulates the release of neurotrophic factors in the brain. - Chewing promotes adult hippocampal neurogenesis. - Chewing is linked to better cognitive performance. - Chewing plays a role in food transport within the mouth. - Chewing breaks down food into smaller particles for easier swallowing. - Chewing mixes food with saliva, aiding in digestion. - Chewing helps form a bolus that can be swallowed efficiently. - Chewing initiates the swallowing reflex. - Chewing exercises the jaw muscles, promoting oral health. - Chewing stimulates saliva production, which helps neutralize acids in the mouth. - Chewing removes food particles that can contribute to dental plaque. - Chewing strengthens the teeth and jawbone. - Insufficient chewing can lead to dental problems such as tooth decay and gum disease.
