Question
Glycemic-index diet: A helpful tool for diabetes?
Is the glycemic-index diet useful for people with diabetes?
Answer
from Maria Collazo-Clavell, M.D.
Some people with diabetes use the glycemic index (GI) as a guide in selecting foods — especially carbohydrates — for meal planning. The glycemic index ranks carbohydrate-containing foods based on their effect on blood sugar level. Foods with a high glycemic-index value tend to raise your blood sugar faster and higher than do foods with a lower value. However, low-index foods aren't necessarily healthier than high-index foods are.
Although the glycemic-index diet has some potential benefits — such as reducing blood sugar levels — it is very complicated. Many factors affect the glycemic-index value of a specific food, including how the food is prepared and what's eaten with it. Also, the GI value for some foods isn't known. For these reasons, the American Diabetes Association has concluded there isn't enough evidence to recommend the general use of a low-glycemic-index diet for people with diabetes.
If you're interested in learning more about this meal-planning tool, talk to a registered dietitian. He or she can help you make changes in your diet.
