Diabetes: Two sensations in your feet that signal dangerously high blood sugar levels – Daily Express

The glycaemic index (GI) is a scale from one to 100 that is used to measure how quickly foods that contain carbohydrates raise blood glucose.

Foods that rank high on the GI index have a more pronounced impact on blood sugar levels.

High GI foods include white bread, potatoes and white rice.

Low or medium GI foods, which are broken down more slowly, include some fruit, vegetables and pulses.
