Glycemic Index and Diabetes

Glycemic Index: What's It All About?

Good carbohydrates, bad carbohydrates. Low glycemic index, high glycemic index. A great tool to help you manage diabetes or lose weight. You might have heard all these statements associated with the glycemic index. What is this glycemic index all about? Is it worth considering as a way to help you control your blood sugar levels?

The Glycemic Index: Food’s Impact on Blood Sugar in Diabetes

Researchers have spent years debating what makes blood sugar levels too high in those with diabetes. Potential culprits have included sugar, carbohydrates in general, simple carbs, starches, and more. The glycemic index is one attempt to measure each individual food’s effect on blood sugar.

If you're trying to lose weight, calories count more than the types of food in your diet, a U.S. Department of Agriculture-Tufts University study shows.

The study shows that after a year, overweight people on a low-carb low-glycemic-index diet lost just as much weight -- 8% of their original weight -- as people on a reduced-fat, high-glycemic-index diet.

"The present results suggest that a broad range of healthy diets can successfully promote weight loss," conclude Sai Krupa Das, PhD, and Susan B. Roberts, PhD, of the USDA's Human Nutrition Center on Aging at Tufts, and colleagues.

High Glycemic Index Foods Are Linked to Health Problems

What researchers have learned is that high glycemic index foods generally make blood sugar levels higher. In addition, people who eat a lot of high glycemic index foods tend to have greater levels of body fat, as measured by the body mass index (BMI). High BMIs are linked to obesity, heart disease, and diabetes.

High glycemic index foods include many carbohydrates such as these:

  • White bread
  • Pasta
  • Rice
  • Low-fiber cereals
  • Baked goods
