The oral serous solution is clear and watery, and contains the digestive enzyme amylase, also known as ptyalin. It is no wonder that these salivary glands are the ones most associated with carbohydrate digestion. The ducts for these glands are near your upper teeth.

The Sublingual glands are located under the tongue and produce a saliva that is primarily mucous. Mucous saliva is thick and gluey. It binds the masticated (chewed) food into a bolus as well as lubricating the esophagus. The ducts for these glands are located on the floor of your mouth.

The Submaxillary glands, also known as the Submandibular glands, are located near the jawbone, secrete both serous and mucous saliva. The saliva reaches your oral cavity via ducts located under your tongue. The Submaxillary glands and the Sublingual glands also produce salivary amylase.

Partners in Health

You now know what chewing well on its own can accomplish, what saliva on its own can accomplish, and even a bit about where that litre (+) of saliva that you produce every day comes from. Now let’s put it all together:

Chewing well combined with saliva are partners in digestion. We all know that chewing well and mixing your food bits with saliva leads to carbohydrate digestion but did you know eating protein-rich meals actually decreases the amount of salivary amylase produced? Eating a carbohydrate-rich meal leads to a slight increase in the amount of salivary amylase produced in your mouth.
Saliva acts as a first defense against bacterial infection. By chewing food well and creating more surface area on which the saliva can act, more potential food-borne bacteria can be killed.
The bicarbonate in saliva may activate the enzyme cellulase found in raw vegetables. The enzyme cellulase digests the fibre cellulose. Together bicarbonate and cellulase begin to digest the raw vegetables. Chewing well also helps to break down the cellulose. However, the combination of the saliva and chewing helps the body to fully digest raw vegetables and receive their nutrients.

Don’t forget – even the most pureed soup or juiced veggies need to be ensalivated. Swish nutrient-rich liquids around in your mouth before you swallow. The carbohydrates present in the soup or juice can be partially digested by your saliva.

I once read that the mouth doesn’t make enough saliva to initiate carbohydrate digestion so if you’re chewing for that reason, don’t bother. Fortunately that ‘idea’ has been thoroughly disregarded by the many who know better.

Chewing well and tasting your food is just plain common sense. The fact that our body produces a substance (saliva) that makes chewing, tasting, and swallowing easier is a bonus to our vitality. Chewing well and saliva - each have their own merits. It’s when they work together that we can really appreciate the partnership that nature has c
