Because the human body cannot absorb nutrients from foods, without breaking them down into smaller parts.
The food that we eat needs to be digested, or broken down, so the particles are small enough to be able to be absorbed into our cells. The process of digestion has four parts. Ingestion, digestion (mechanical and chemical), absorption, and elimination.
Most of the digestion of food occurs in the small intestine. This is where enzymes break down proteins, carbohydrates, and fats into smaller molecules that can be absorbed by the body. The small intestine is also where nutrients are absorbed into the bloodstream.
The long coiled tube in which food is digested and absorbed is the small intestine. It is responsible for breaking down food into nutrients and absorbing these nutrients into the bloodstream to be used by the body for energy and other functions. The small intestine is an essential part of the digestive system, where most of the digestion and absorption of nutrients takes place.
Bolus is a mass of chewed food mixed with saliva, ready to be swallowed, while chyme is the partially digested food that passes from the stomach into the small intestine for further digestion and absorption of nutrients.
The movement of digested food from the digestive system to the circulating fluid is called absorption. This process mainly occurs in the small intestine where nutrients are taken up into the bloodstream for distribution throughout the body.
There are many digestive juices in our body to digest the food but some kind of food is not digested by our digestive juices of any bacteria eg.Dietary fibres (cellulose) is not digested by our body as it needs to be digested by some special kind of bacteria which is only present in rumens.Hence also verified that we cannot digest all kinds of food.

To change food to a form that can be used by the body. Some require more digestion, some less.
Food must be chemically digested because the substances which our body needs cannot be absorbed into the blood until they have been broken down into small, soluble chemicals with the help of enzymes in our mouth. When the food is digested, its molecules are small enough to pass through the wall of the small intestine by diffusion.
Food is stored before it is digested in your stomach.
The food that cannot be digested goes to the large intestine.
The food that cannot be digested goes to the large intestine.
