What is a hypothesis for how soda cracker might affect saliva?

Reasoning: Soda crackers are a type of dry, starchy food that requires a significant amount of chewing. This process of chewing stimulates the salivary glands to produce more saliva, which helps to break down the food and make it easier to swallow. Additionally, the starch in the crackers can also bind to water molecules in the mouth, which can further increase the production of saliva.
