Mastication

Definition

The mechanical process of grinding food by teeth and jaws. It initiates digestion by reducing food into smaller particles and mixing it with saliva.

How it works

Mastication is the first step in digestion. It transforms solid foods into fine particles, increasing their contact surface with digestive enzymes. This process also facilitates the formation of the food bolus and stimulates salivary glands to produce saliva, containing an enzyme called salivary amylase. Adequate mastication significantly improves digestion and nutrient absorption in the rest of the digestive system.

Role

Prepares food for swallowing and initiates mechanical and chemical digestion.

Examples

• Chewing bread
• Grinding fruits
• Chewing meat

Recommendations

Chew each bite at least 20 to 30 times to optimize digestion. Take time to savor meals without rushing.

Key takeaway

Slow and complete mastication is essential for effective digestion.
