Low and high glycemic index foods seem to have different benefits for different types of exercise performance. Based on the research presented in this Nutritionist’s View column, it appears that low glycemic index foods are better to consume prior to longer duration events, while high glycemic index foods seem to fare better for shorter distances and intermittent activities. Nonetheless, these statements are broad, and even within the articles presented, there were variations. These variations certainly depended on how the food was given (bar or meal), how much was consumed, when the food was provided, and what type of activity was performed.
