Glycemic - index is a number which is assigned to a particular carbohydrate - food. Lower is the number, the more benificial it is for the diabetic people. According to the pattern of the foods, they are classified as low GI, medium GI or high GI. Foods with low GI are benificial for the people suffering from diabetes. There are certain foods having low GI index such as cabbage, cauliflower, spinach etc and the GI number of the same being up to 55 and medium GI ranging from 56 and 69 cover garlic, almond, sweet potato, raisins etc. High GI exceeding beyond 70 should be consumed less because of elevation of sugar - level. Potato comes under this class.
Low glycemic - food is always benificial for the diabetic patients.

Glycemic Index (GI) of Food:-
Carbohydrate is the main component of majority of the food items. Measurement carried out on carbohydrate containing food items is known as Glycemic Index and this measurement is mainly done to study the impact of these food items made on blood sugar. It does not measure the carbohydrate present in food before it is consumed. It actually measures the rise of blood sugar that occur in our body after we consume that food item containing carbohydrate.

Glycemic Index Values:-
Each and every food item that we consume has its own glycemic index value. Our food stuffs can be classified on the basis of glycemic index into following values:-
1) Very low GI- Carbohydrate value is less than 5 gm. No GI value.
2) Low GI- Carbohydrate value is more than 5 gm but less than 12 gm. GI value is 55 or less.
3) Medium GI- GI value 56-69.
4) High GI- GI value is 70 or even more.

Association between Glycemic Index and Diabetes:-
Low GI diets can be used to control diabetes. If a person follows low GI diet, he can delay the onset of diabetes even if has a family history of it. One who has already been dealing with this disorder can very well control it by following a diet chart which mainly comprises of low glycemic index value food stuff. Even though diabetic individuals are consuming medium or high glycemic index value food stuffs, they can balance it out by consuming low GI value as well as very low GI value foods too.
High GI value food stuffs raises blood glucose level in body and thus diabetic individuals should avoid them. Low GI foods release glucose in blood at very slow pace and also very steadily. Thus, there is no abrupt increase in blood sugar level of an individual which can be fatal in case of diabetic individual who are not able to metabolize the sugar in their body due to lack of insulin producing capacity of their pancreas.
