Explaining the Need for Digestion

Why does food need to be digested?

so your body can take all the nutrients from the food and use it for your body to work

Digestion is a process where the larger, insoluble food molecules are converted to smaller, soluble molecules. The large molecules can't be used by our body, so digestion essentially breaks down food into a form in which the body can use to provide with essential nutrients for growth and repair, to provide us with energy and to store energy etc.
