What does saliva do to food you eat?

Saliva is an important component of the digestive process. It is a clear liquid produced by the salivary glands in the mouth. It contains water, electrolytes, enzymes, and mucus. Saliva helps to break down food into smaller pieces, making it easier to swallow and digest.

The main enzyme in saliva is amylase. Amylase breaks down carbohydrates, such as starches, into smaller sugars. This process begins in the mouth and continues in the stomach and small intestine. Other enzymes in saliva help to break down proteins and fats.

Saliva also helps to lubricate the mouth and throat, making it easier to swallow. It also helps to protect the teeth from decay by neutralizing acids and providing a protective coating.

In addition to its role in digestion, saliva also plays a role in speech, taste, and oral health.
