High-GI Carbohydrates

Meaning

High-GI Carbohydrates are dietary carbohydrate sources that are rapidly digested and absorbed, leading to a quick and significant elevation in blood glucose concentration, consequently triggering a substantial and acute release of insulin from the pancreatic beta cells. These foods typically have a Glycemic Index (GI) value of 70 or higher. While generally discouraged for routine consumption due to their potential to induce insulin resistance and subsequent metabolic stress, they serve specific, tactical roles in sports nutrition.
