Take a bite of bread. As you chew, its starch starts a journey: where does it go before becoming fuel-or something your body saves? Digestion chops that starch into smaller sugars, mostly glucose. The bread is no longer just food; it has become tiny glucose molecules. In the small intestine, glucose passes into your bloodstream and travels around your body. Here's the turn: carbs do not become energy directly in your stomach. Glucose is the handoff. Your cells use some to make usable energy, while insulin helps coordinate where the rest goes. Some is stored in your liver and muscles as glycogen, ready for later. Fiber follows a different path, and when energy exceeds immediate needs and storage space, some may eventually be stored as fat. So that bite of bread? Broken into glucose, used now or stored, depending on what your body needs.
