Our bodies were never designed to be constantly chewing and there are significant neurological mechanisms in the chewing process. When you chew, your brain thinks it is going to get food and secretes digestive enzymes, such as Amylase in the mouth to break down carbohydrates. This is the first stage of digestion. It then signals the gastrointestinal track and pancreas to secrete more enzymes, such as Protease and Lipase in preparation for what it believes to be food coming down that needs to be digested. This is the normal process by which protein and fat are broken down. This unnatural process can cause bloating.

Hormone imbalances occur, due to our digestive system being controlled and regulated by our autonomic nervous system, such as insulin and cortisol being secreted. The stomach then starts producing Hydrochloric Acid. This can't be used and can create potential digestive dysfunction, such as Acid Reflux Ulcers and Bruxism (teeth grinding and clinching).

Biomechanical imbalances like forward head posture, which is a result of excessive chewing can strain the cervical vertebrae causing the thoracic and lumbar vertebrae to compensate, making one hip or shoulder lower than the other. TMJ can also occur as well as headaches and since most people chew on one side, asymmetry faces. Gums containing artificial flavoring and other toxic chemicals can lead to a long list of adverse consequences.
