Why is it necessary to Chew so well?

We have been given the most sophisticated and perfect tools for chewing our food correctly. These include specially designed teeth, a tongue that controls and performs so many functions, cheeks that also assist us to chew, the production of saliva which in turn provides enzymes – all to assist us in chewing correctly so as to change the food to a nutritious bolus for the next stage of digestion. Why? It must surely be because we need to chew our food well, being a critical and important part of the Digestive System Process – and the ONLY part of the Digestive Process that WE have been given the responsibility of doing correctly and efficiently.
