Glycemic Index (GI) is a measure of the impact that foods that contain carbohydrates have on our blood sugar. In my other blogs, I have mentioned that carbohydrates are essentially sugars and therefore cause an increase in blood sugar depending on the type of food being consumed.
The simplest way to understand Glycemic Index, is that foods containing a high GI are bad for you and foods low in GI are good for you. Any food that has a GI between 56-69 is considered a medium GI and anything with a GI higher than 70 is a high GI.
It is not surprising that potato has a high GI but even foods that at least I thought were healthy like beet, corn, apricot, cantaloupe, papaya, watermelon (its just sweet water anyone?) have a medium GI.
Since it is now clear that your diet should at most contain 150 gms or carbohydrates, choose your foods well, especially that come loaded with carbohydrates with a high GI.
