Low GI Low GI – Digested and absorbed slowly and glucose is released into the bloodstream over a long period of time Benefits: longer exercise session or improved performance in an endurance event
High GI High GI- Digested and absorbed quickly and raised blood sugar levels rapidly over a short period of time. Benefits: Can be used DURING or AFTER an event to provide energy fast.
