What is the correct term for the process of breaking down food into simpler components?

The process of breaking down food into simpler components is known as digestion. This process involves both mechanical and chemical actions that convert food into smaller, absorbable nutrients. Mechanical actions include chewing and the churning action of the stomach, while chemical digestion involves enzymes that break down proteins, fats, and carbohydrates into their basic building blocks—amino acids, fatty acids, and simple sugars.

Understanding digestion is crucial in the context of dental nursing because oral health can significantly affect the initial stages of digestion. For instance, proper chewing is essential for efficient digestion, and dental issues can impede this process. Additionally, a thorough knowledge of digestion helps in comprehending how nutrition impacts overall health, including oral health, and informs dietary advice a dental nurse may provide to patients.
