While glycemic index promotes healthy choice in theory, it is not a reliable measure. A senior author of the study suggests that individuals should choose whole foods such as whole grains, fruits, and vegetables, and lean meats. Glycemic index also only observes the impact of carbohydrates in isolation, rather than looking at the effects of a whole meal; individuals eat more than carbohydrates in any given meal, which renders the isolated effects of a single carbohydrate source far less meaningful in real life situations. While advertisements may continue to tout the benefits of low GI food products, research has shown that the benefits are limited.
