Glycemic Index Diet

Glycemic Index Diet or GI diet is a diet meant for people suffering from diabetes. Also known as a low glycemic diet, the index is valued as the ranking of various carbohydrates that measure the rate of increase of the blood sugar level with the ingestion each food type. The diet was first introduced by Dr. David J. Jenkins, a professor at the Toronto University. It was published in a book form later on by Rick Gallop , the erstwhile president of the “Heart and Stroke Foundation”, Ontario.

The diet measures all food items against the GI of glucose which is set at 100. Contrary to the popular belief, sugars are attributed with a medium Glycemic index making professionals argue in favor of incorporating sugars as a part of the diabetes diet.

The diet does not work instantaneously. On the contrary, it takes a long time with the body weight and blood sugar levels being controlled and maintained for a longer period.

Glycemic Index Diet: Characteristics

Food that is digested slowly is considered to be good and has a low GI. High GI food stuffs are not considered to be healthy with starch and carbohydrates being rated higher than sugar by this particular diet. However, it has also been found out that adding a little vinegar or fresh fruit juice to any food item lowers its glycemic index considerably.

The principle of the diet is that a person eating low GI foods is not bound to feel hungry in between meals.

Wholegrain breads, oatmeal, fresh vegetables and fruits are all low GI making them ideal for a diabetic. Legumes, kidney beans, dairy products, buckwheat and new potatoes are also low in glycemic index making them acceptable to the patients with high blood glucose levels.
