Question

How does chewing food speed up digestion?

Answer 1

Hint: Mastication, or chewing, is the first phase in your digestive process, and it's one you don't want to rush through. Chewing breaks down huge particles of food into smaller, more easily digestible pieces. Chewing also aids the absorption of nutrients from food particles as they pass through your intestines.

Complete answer:
The simple process of chewing food in your mouth aids in the breakdown of larger food particles into smaller ones. This relieves stress on the oesophagus, allowing the stomach to better digest your food.
Chewing breaks the meal down into tiny pieces, thereby increasing its surface area. This means digestive enzymes may access more of the food at any given time, allowing them to break it down more quickly.The small glands on the tongue and the inside surface of the mouth generate mucus, which softens the food particles. Saliva contains an enzyme called amylase, which starts the digestive process. This causes the starch in food particles to be broken down. Swallowing is also made easier by chewing food. Chewing food causes the production of components in the saliva to rise, which aids in overall digestion and prevents digestive disorders.
It takes time (generally 20 minutes) for your brain to signal to your stomach that you're full, and this may explain why one study found people reported feeling fuller when they ate slowly.

Note:-
When they ate slowly and chewed more slowly, they consumed around 10% fewer calories than when they ate quickly. Longer chewing also leads to less calories consumed and higher levels of appetite-regulating hormones, which inform your brain when to quit eating. Chewing food is actually considered a component of the digestive process.
