Low GI diets are very healthy and foods with a low GI include breakfast cereals based on oats, barley, bran and wholegrain bread. White bread has a high GI. It may also be advisable to reduce consumption of potatoes ad increase the amount of fruit and vegetables you eat, preferably to the extent of consuming at least five different portions a day.

The GI range suggests that low is 55 or less whereas medium GI values fall between 56 and 79 and a high GI value is depicted by a figure of 70 or more. Glycemic Load (GL) expands on GI to provide a measure of total Glycemic response to a food. To calculate the load, simply multiply the Index percentage by the number of grams of carbohydrate per serving. Use food labels to find out some of these figures. A typical diet contains anything from 60-180 GL units per day. The GL range indicates low figures of 10 or less, medium figures of 11-19 and high figures of 20 or more. Per day, a low GL is considered to be less than 80 while more than 120 represents a high GL.
