Kogelnig: The mouth is a complex system made up of different parts. The lips are highly sensitive to temperature and touch and assess the food’s physical characteristics, i.e. whether it is hot, cold, coarse, prickly, etc. Our teeth play an important role by breaking down the food into smaller pieces. The better you chew, the more digestive enzymes are released in saliva, speeding up the food’s breakdown. Chewing kicks off the whole digestive process. ‘Well chewed is half digested,’ we say! Thorough chewing allows us to really enjoy our food, but is also vital to achieve satiation. The feeling of satiety protects the stomach from overfilling and its consequences such as belching, reflux, heartburn, bloating, other problems of the digestive tract, and putting on weight, of course.
