Different carbohydrates are digested and absorbed at different rates, and GI is a ranking of how quickly each carbohydrate-based food and drink makes blood glucose levels rise after eating them.
The higher the ranking, the more pronounced effect a given food will have on blood sugar levels.
High GI foods include:
- Sugar and sugary foods
- Sugary soft drinks
- White bread
- Potatoes
- White rice.
Low or medium GI foods, which are broken down more slowly and cause a gradual rise in blood sugar levels over time, include some fruit, vegetables and pulses.
