How is food used by your body?

Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose ... However, our bodies need insulin in order to use or store glucose for energy.

The body breaks the foods down into their simpler components: carbohydrates (sugars), lipids (fats), protein (building blocks of muscles), enzymes, and more. The body then re purposes these components for whatever it needs, for example, sugars are used with insulin to provide energy.
