Why most food esten by humans must be digested before they can be used by the body?
Food must be digested before it can be used by the human body. This is due to the fact that food molecules are too big for the body to do anything with, so the body requires chemical and mechanical digestion to pull out the nutrients inside the food. Anything left over after the nutrients are used up is expelled from the body via the excretory system.
