Question: What is the glycemic index? Dr. Jordan Lipton: Glycemic index, I wont be able to describe exactly how it's measured but basically it was developed in Canada by a research at the University of Toronto and it shows that or it basically measures the glucose impact or the blood sugar impact that a set amount of carbohydrate in a certain food will have on that person. So, for example, celery if you have 50 grams of carbohydrate in celery first of all you would fill up the whole room to get 50 grams of carbohydrate that would do nothing to your blood sugar, it might even lower your blood sugar because you use that more energy in eating it than do you actually get it from a celery but on the other hand a piece of white bread will raise your blood sugar a lot quicker than a piece of whole grain bread and the whole grain bread therefore had doesn't result in all these ups and downs in your blood sugar. So, it's much better to have a smooth increase where your body can, whether you body and your insulin whether you are Type 1 diabetic giving yourself insulin or Type 2 diabetic or a non-diabetic that insulin will just work more effectively if it's a slow rise in blood sugar. Same with other types of vegetables or other types of foods like potatoes surprising enough, white potatoes have a much higher glycemic index and raise your blood sugar a lot faster than sweet potatoes. So people are thinking, oh they will not have sweet potato because sweet is not good for you, you believe or not its much better for you if you have the equal amount of sweet potato to white potato you can get a less of a glucose impact and candies of course are very bad because the ones with sugar will raise your blood sugar quickly, the chocolate even though an ounce of dark chocolate is good for you to certain extent. If you have a 16 ounce candy bar every day then that's going to raise your blood sugar, raise your fat and its not good for you but the glycemic index is very, very high and there are certain fruits that are similar there. Some fruits don't have a high glycemic index and a candy -- but apples are better than bananas, there is a grain, an indian grain called -- it's like a pea which has an incredibly low glycemic index and very good for you as protein, it's just very good for you and so if you can find things like that and to lose weight, you are Type 2 diabetic you are going to get better or you can get better control.
