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.

Why only the starchy foods start to be chemically digested?
It's because in the mouth we masticate the food.Mastication increases the surface area of the food which helps to accelerate the breakdown of the carbohydrate molecules.Whereas in other parts of the digestive system where foods are chemically digested mastication does not occur.so foods containing starch start to be chemically digested.
