Study questions value of glycemic index
Date: 17.10.2011
Potatoes and other reportedly high-GI foods might not be the dietary villains that recent publicity, books and health-based programmes would claim them to be, a new University of Otago study suggests.
The Glycemic Index is a measure of the effects of carbohydrates on blood sugar levels.
The researchers found that the GI for each meal was not as high as anticipated. From the GIs of the foods used the researchers expected that the potato meal would have an overall GI of 65, which falls within the medium range; instead at 53, the meal fell just within the low range. Therefore, although potato is a high-GI food, a meal containing potato is not necessarily so, Dr. Venn says.
