Low Glycemic Index Foods in Diabetic Management

Glycemic index is a value given to foods based on their ability to control blood sugar levels. It is expressed in numbers between 0 – 100. It gives an idea about how fast your body converts the carbohydrates in food to glucose. Some refined foods can elevate your blood sugar levels very fast. Refined flour/maida, breads, biscuits, corn flakes, raw rice, and refined sugar are low in fiber and these are foods which have a very high glycemic index. If eaten in large amounts, these carbs will elevate the blood sugar levels even with the support of insulin or diabetic drugs. This is because these are low in fiber and easily digested by your system and converted to glucose faster. Whereas, the carbs which we get from complex sources like parboiled rice, ragi, oats, wheat (whole), jowar, bajra, vegetables, some fruits, etc take more time to get digested. Two foods with the same amount of carbs can give you different glycemic index numbers. Smaller the number, the better it is for diabetic patients.

<55 – low (good)

56 – 69   – Medium

>70 – high (bad)

The high glycemic index of a food can be brought down by adding other foods that are low in glycemic index. For example, when you eat rice, include a lot of veggies in your diet. Mixing rice with lentils and vegetables lowers the glycemic index of the meal. But always remember, the glycemic index is not the only criteria you must look into while making a food choice. The nutritive value and the vitamin content of the food are also very important.

Adding fats, acids like lime juice or vinegar, etc can reduce the glycemic index of your food. Adding a spoon of ghee into your rice actually reduces the glycemic index of the meal. Portion size is also very important in glycemic index value monitoring. More of the carbs you take, more they can alter your blood sugar levels.

For low glycemic load add a variety of whole grains, nuts, legumes, green vegetables, fruits, etc in your diet. Avoid refined food mentioned above from your diet. Reduce the intake of processed foods, refined sugar, candies, cakes, and sweetened beverages. Enjoy high glycemic index foods in smaller portions when you add it in your diet.
