Can a Low GI Diet Prevent Diabetes?

Low GI Diet for Diabetics

A low GI diet for Diabetics suggests that foods with a low GI rating are helpful for keeping blood glucose levels steady. By eating foods that have a low glycemic index, you can lose excess weight and reduce the risk of developing diabetes and other diseases.  A low GI diet for diabetics, encourages eating plenty of carbohydrates and unrefined foods which won’t spike blood glucose levels because they take longer to digest. High GI foods such as white rice and potatoes raise blood glucose levels quickly, while low GI foods such as oatmeal, quinoa, nuts and cottage cheese generally lead to satiety and weight loss.

How does the Glycemic Index work?

On the glycemic chart, foods and beverages are ranked according to their impact on blood sugar levels. The glycemic index chart only rates foods with carbohydrates mainly because they have the greatest impact on blood sugar. Most refined and processed foods such as white bread are generally given a high glycemic rating. Such foods are digested rapidly and increase both blood sugar levels and insulin very quickly. On the other hand, low glycemic foods and drinks contain more fiber and nutrients, are harder to digest, and they don’t cause blood sugar spikes.

Glycemic Index Range for Diabetics

  • High glycemic index (70 and above): donuts, baked potatoes, watermelon, instant white rice, pretzel, French fries and plain white bread.Low GI Diet for Diabetics,
  • Medium (Between 59 and 69): Mangoes, corn chips, raisins, bananas, raw pineapple and papaya.
  • Low GI (59 and bellow): Apple, skim milk, kidney beans, peanuts, lentils and strawberries.

The main aim of a low GI diet for diabetics is to consume complex carbohydrates with healthy fats and lean protein to keep digestion steady and slow in order to improve the feeling of fullness. It encourages avoiding processes foods that are broken down into glucose very fast, which triggers a hormonal response that signals hunger. This is a vicious cycle for most dieters who are trying to limit calorie intake.

Factors affecting glycemic index

The glycemic index depends on cooking methods, variety of food products, processing and ripeness of fruits. Riper fruits generally have high GI. On the other hand processed juices generally have a higher GI compared to fresh fruit juices because processed juices contain sugar additives. When it comes to variety, short grain brown rice has a lower GI compared to short grain white rice.
