Amylase is a digestive enzyme and is used to digest carbohydrates and sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. If Amylase is imbalanced, it can be either due to not chewing enough before swallowing or the diet being too carbohydrate/sugar-rich.
Experts have a lot to say about chewing. One standard piece of advice is to chew your food an estimated 32 times before swallowing. (It takes fewer chews to break down soft and water-filled food.) The goal of chewing is to break down your food to lose texture. Lower your refined carbohydrate and sugar consumption daily by 10% and replace them with more complex carbohydrates or vegetables. Opting for a digestive enzyme supplement containing Amylase can also help.
