Do you consider the glycemic index of foods in your meal planning?Poll dates: January 20 - 27, 2002

The glycemic index is a measure of how much a food increases blood sugar after eaten. For example, some people find that a food raisess their blood sugar more than another food, even though the two foods have the same carbohydrate content. The food that causes the larger increase is said to have a higher glycemic index.
While many people find the glycemic index helpful in their meal planning, a study published in 1999, entitled Carbohydrate Counting Works Regardless of Amount of Carbohyrdate Eaten, found that the glycemic index of foods did not affect pre-meal insulin requirements. Furthermore, new ADA guidelines on diabetes and nutrition discount the effect of the glycemic index on diabetes control:Although low glycemic index diets may reduce postprandial glycemia, the ability of individuals to maintain these diets long-term (and therefore achieve glycemic benefit) has not been established. The available studies in persons with type 1 diabetes in which low glycemic index diets were compared with high glycemic index diets (study length from 12 days to 6 weeks) do not provide convincing evidence of benefit.1
